203-827: Champagne ( / ʃ æ m ˈ p eɪ n / ; French: [ʃɑ̃paɲ] ) is a sparkling wine originated and produced in the Champagne wine region of France under the rules of the appellation , which demand specific vineyard practices, sourcing of grapes exclusively from designated places within it, specific grape-pressing methods and secondary fermentation of the wine in the bottle to cause carbonation . The grapes Pinot noir , Pinot meunier , and Chardonnay are used to produce almost all Champagne, but small amounts of Pinot blanc , Pinot gris (called Fromenteau in Champagne), Arbane , and Petit Meslier are vinified as well. Champagne became associated with royalty in
406-405: A glass (or vitreous solid) is a non-crystalline solid formed by rapid melt quenching . However, the term "glass" is often defined in a broader sense, to describe any non-crystalline ( amorphous ) solid that exhibits a glass transition when heated towards the liquid state. Glass is an amorphous solid . Although the atomic-scale structure of glass shares characteristics of the structure of
609-436: A supercooled liquid , glass exhibits all the mechanical properties of a solid. As in other amorphous solids , the atomic structure of a glass lacks the long-range periodicity observed in crystalline solids . Due to chemical bonding constraints, glasses do possess a high degree of short-range order with respect to local atomic polyhedra . The notion that glass flows to an appreciable extent over extended periods well below
812-809: A turquoise colour in glass, in contrast to copper(I) oxide (Cu 2 O) which gives a dull red-brown colour. Soda–lime sheet glass is typically used as a transparent glazing material, typically as windows in external walls of buildings. Float or rolled sheet glass products are cut to size either by scoring and snapping the material, laser cutting , water jets , or diamond-bladed saw. The glass may be thermally or chemically tempered (strengthened) for safety and bent or curved during heating. Surface coatings may be added for specific functions such as scratch resistance, blocking specific wavelengths of light (e.g. infrared or ultraviolet ), dirt-repellence (e.g. self-cleaning glass ), or switchable electrochromic coatings. Structural glazing systems represent one of
1015-518: A "high end" table wine or wine cellar, and comes from the Latin word "cava" which means cave in English. Caves were used in the early days of Cava production for the preservation or aging of wine. Today Cavas have become integrated with Catalan and also Spanish family traditions and is often consumed at any kind of celebrations (baptism, marriages, banquets, dinners and parties). The sparkling wine of Cava
1218-708: A blend of the two (these being the only two black grapes permitted within the Champagne AOC appellation ). A French term that means "white from whites", and is used to designate Champagnes made exclusively from Chardonnay grapes or in rare occasions from Pinot blanc (such as La Bolorée from Cedric Bouchard). The term is occasionally used in other sparkling wine-producing regions, usually to denote Chardonnay-only wines rather than any sparkling wine made from other white grape varieties. Rosé Champagnes are characterized by their distinctive blush color, fruity aroma, and earthy flavor. Rosé Champagne has been produced since
1421-400: A broader range of consumers by highlighting the different qualities of sparkling wine versus ordinary wine, associating champagne brands with royalty and nobility, and selling off-brands under the names of importers from France at a lower cost. However, selling off-brands at a lower price proved to be unsuccessful, since "there was an assumption that cheap sparkling wine was not authentic." Since
1624-506: A chain reaction, with it being routine for cellars to lose 20–90% of their bottles this way. The mysterious circumstance surrounding the then unknown process of fermentation and carbonic gas caused some critics to call the sparkling creations "The Devil's Wine". There are more than one hundred champagne houses and 19,000 smaller vignerons (vine-growing producers) in Champagne. These companies manage some 32,000 hectares of vineyards in
1827-485: A clear "ring" sound when struck. However, lead glass cannot withstand high temperatures well. Lead oxide also facilitates the solubility of other metal oxides and is used in coloured glass. The viscosity decrease of lead glass melt is very significant (roughly 100 times in comparison with soda glass); this allows easier removal of bubbles and working at lower temperatures, hence its frequent use as an additive in vitreous enamels and glass solders . The high ionic radius of
2030-427: A complementary element in food and wine pairing . Just after disgorgement a "liqueur de dosage" or liqueur d’expédition – a blend of, typically, cane sugar and wine (sugar amounts up to 750 g/litre) – is added to adjust the levels of sugar in the Champagne when bottled for sale, and hence the sweetness of the finished wine. Today sweetness is generally not looked for per se, and dosage
2233-435: A consistent rosé appearance from year to year. The character of rosé Champagne has varied greatly since its production began. Thought to be a sign of extravagance when originally introduced, by the early 20th century these wines were colloquially known as "Pink Champagne," and had gained a reputation of frivolousness or even dissipation. The 1939 Hollywood film Love Affair was reportedly approached to promote it by featuring
SECTION 10
#17328022623772436-464: A designation for the traditional method, the term Crémant was given its present definition. This meant that the use of "Crémant" in the Champagne region was discontinued and additional French Crémant AOCs were created from 1990, starting with Bordeaux and Limoux. Since the designation Crémant is not reserved exclusively for French use (as a result of it replacing méthode champenoise ), it may also be used by producers in other EU countries which fulfill
2639-400: A few producers. Previous directives of INAO make conditional allowances according to the complex laws of 1927 and 1929, and plantings made before 1938. Before the 2010 regulations, the complete list of the actual and theoretical varieties also included Pinot de Juillet and Pinot Rosé . The Gamay vines of the region were scheduled to be uprooted by 1942, but due to World War II , this
2842-443: A green tint in thick sections. Manganese dioxide (MnO 2 ), which gives glass a purple colour, may be added to remove the green tint given by FeO. FeO and chromium(III) oxide (Cr 2 O 3 ) additives are used in the production of green bottles. Iron (III) oxide , on the other-hand, produces yellow or yellow-brown glass. Low concentrations (0.025 to 0.1%) of cobalt oxide (CoO) produce rich, deep blue cobalt glass . Chromium
3045-408: A human timescale. Silicon dioxide (SiO 2 ) is a common fundamental constituent of glass. Fused quartz is a glass made from chemically pure silica. It has very low thermal expansion and excellent resistance to thermal shock , being able to survive immersion in water while red hot, resists high temperatures (1000–1500 °C) and chemical weathering, and is very hard. It is also transparent to
3248-470: A lengthy set of requirements specifying most aspects of viticulture . This includes pruning, vineyard yield, the degree of pressing, and the time that wine must remain on its lees before bottling. It can also limit the release of Champagne to market to maintain prices. Only when a wine meets these requirements may it be labelled Champagne. The rules agreed upon by the CIVC are submitted for the final approval of
3451-405: A lighter alternative to traditional glass. Molecular liquids, electrolytes , molten salts , and aqueous solutions are mixtures of different molecules or ions that do not form a covalent network but interact only through weak van der Waals forces or transient hydrogen bonds . In a mixture of three or more ionic species of dissimilar size and shape, crystallization can be so difficult that
3654-421: A link to that producer and presented in non-standard bottle shapes (following Dom Pérignon's lead with its 18th-century revival design). A French term (literally "white from blacks" or "white of blacks") for a white wine produced entirely from black grapes. The flesh of grapes described as black or red is white; grape juice obtained after minimal possible contact with the skins produces essentially white wine, with
3857-561: A long period at a temperature just insufficient to cause fusion. In this way, the crystalline, devitrified material, known as Réaumur's glass porcelain is produced. Although generally transparent to visible light, glasses may be opaque to other wavelengths of light . While silicate glasses are generally opaque to infrared wavelengths with a transmission cut-off at 4 μm, heavy-metal fluoride and chalcogenide glasses are transparent to infrared wavelengths of 7 to 18 μm. The addition of metallic oxides results in different coloured glasses as
4060-482: A mass of hot semi-molten glass, inflating it into a bubble using a hollow blowpipe, and forming it into the required shape by blowing, swinging, rolling, or moulding. While hot, the glass can be worked using hand tools, cut with shears, and additional parts such as handles or feet attached by welding. Flat glass for windows and similar applications is formed by the float glass process, developed between 1953 and 1957 by Sir Alastair Pilkington and Kenneth Bickerstaff of
4263-628: A minimum of 15 months on their lees for non-vintage, 24 months for vintage, and 36 for riserva. Minimum alcohol content must be of 11.5%, or 12% for riserva. Trento DOC wines are distinguished by their straw-yellow color. Prosecco is made in both fully sparkling ( spumante ) and lightly sparkling ( frizzante ) styles. The wine is produced in the cool hills around the town of Valdobbiadene and are generally dry but sweeter examples are produced. v.f.q.p.r.d. (Vini frizzanti di qualità prodotti in regioni determinate): quality vini frizzanti made within defined regions are generally labeled as such. Sekt
SECTION 20
#17328022623774466-474: A mix of the two. Four other grape varieties are permitted, mostly for historical reasons, as they are rare in current usage. The 2010 version of the appellation regulations lists seven varieties as allowed, Arbane , Chardonnay, Petit Meslier , Pinot blanc , Pinot gris , Pinot meunier, and Pinot noir. The sparsely cultivated varieties (0.02% of the total vines planted in Champagne) of Arbanne, Petit Meslier, and Pinot blanc can still be found in modern cuvées from
4669-421: A mixture of sugar and yeast. The introduction of a fresh yeast and food source (the sugar) triggers the fermentation process in the bottle that the wine will eventually be sold in. Through the process of riddling and eventually disgorgement , the dead yeast cells (called lees ) are removed from the wine while still maintaining the dissolved carbon dioxide gas. A dosage mixture of fresh wine and some sugar syrup
4872-453: A non-crystalline intergranular phase of grain boundaries . Glass-ceramics exhibit advantageous thermal, chemical, biological, and dielectric properties as compared to metals or organic polymers. The most commercially important property of glass-ceramics is their imperviousness to thermal shock. Thus, glass-ceramics have become extremely useful for countertop cooking and industrial processes. The negative thermal expansion coefficient (CTE) of
5075-401: A plastic resin with glass fibres . It is made by melting glass and stretching the glass into fibres. These fibres are woven together into a cloth and left to set in a plastic resin. Fibreglass has the properties of being lightweight and corrosion resistant and is a good insulator enabling its use as building insulation material and for electronic housing for consumer products. Fibreglass
5278-433: A preservative. Benoît Gouez, cellar master of Moët & Chandon says that sugar helps champagne recover from the oxidative shock of disgorgement, and contributes to the wine's aging potential. Wines labeled Brut Zero , more common among smaller producers, have no added sugar and will usually be very dry, with less than three grams of residual sugar per litre in the finished wine. The following terms are used to describe
5481-416: A professor of food biochemistry, released the findings of their chemical analyses of the Champagne, and particularly noted the fact that, although the chemical composition of the 170-year-old Champagne was very similar to the composition of modern-day Champagne, there was much more sugar in this Champagne than in modern-day Champagne, and it was also less alcoholic than modern-day Champagne. The high sugar level
5684-462: A refractive index of 1.4 to 2.4, and an Abbe number (which characterises dispersion) of 15 to 100. The refractive index may be modified by high-density (refractive index increases) or low-density (refractive index decreases) additives. Glass transparency results from the absence of grain boundaries which diffusely scatter light in polycrystalline materials. Semi-opacity due to crystallization may be induced in many glasses by maintaining them for
5887-415: A slightly yellower colour than wine from white grapes. The colour, due to the small amount of red skin pigments present, is often described as white-yellow, white-grey, or silvery. Blanc de noirs is often encountered in Champagne, where a number of houses have followed the lead of Bollinger 's prestige cuvée Vieilles Vignes Françaises in introducing a cuvée made from either pinot noir, pinot meunier or
6090-420: A small amount of still red wine to a sparkling wine cuvée . Champagne is light in color even when it is produced with red grapes, because the juice is extracted from the grapes using a gentle process that minimizes contact with the skins. By contrast, Rosé Champagne, especially that created by d'assemblage , results in the production of rosé with a predictable and reproducible color, allowing winemakers to achieve
6293-492: A source for the ongoing effervescence are not natural imperfections in the glass, but actually occur where the glass has been etched by the manufacturer or the customer. This etching is typically done with acid, a laser, or a glass etching tool from a craft shop to provide nucleation sites for continuous bubble formation (note that not all glasses are etched in this way). In 1662 this method was developed in England, as records from

6496-412: A spinning metal disk. Several alloys have been produced in layers with thicknesses exceeding 1 millimetre. These are known as bulk metallic glasses (BMG). Liquidmetal Technologies sells several zirconium -based BMGs. Batches of amorphous steel have also been produced that demonstrate mechanical properties far exceeding those found in conventional steel alloys. Experimental evidence indicates that
6699-435: A structural analogue of silica, fluoride , aluminate , phosphate , borate , and chalcogenide glasses) have physicochemical properties useful for their application in fibre-optic waveguides in communication networks and other specialised technological applications. Silica-free glasses may often have poor glass-forming tendencies. Novel techniques, including containerless processing by aerodynamic levitation (cooling
6902-413: A structurally metastable state with respect to its crystalline form, although in certain circumstances, for example in atactic polymers, there is no crystalline analogue of the amorphous phase. Glass is sometimes considered to be a liquid due to its lack of a first-order phase transition where certain thermodynamic variables such as volume , entropy and enthalpy are discontinuous through
7105-505: A term and spelling in 1805 (see Weltsekttag ) and from the late 18th century onwards begins to appear in technical manuals published for the use of wine merchants, vintners and oenophiles in general. The 1919 Treaty of Versailles forbade Germany the use of this name, long before European Union regulations prohibited its use outside the Champagne region. Sekt was initially an informal German name for sparkling wine, coined in Berlin 1825, but
7308-475: A traditional Champagne grape, Chardonnay was not used in the production of Cava until the 1980s. Espumante ( Portuguese pronunciation: [ɨʃpuˈmɐ̃tɨ] ) is the Portuguese version of a sparkling wine. Unlike Cava, which is produced solely in northern climates, Espumante is not only produced in the northern wet region of Vinho Verde, but also throughout Portugal all the way to the southern region of
7511-521: A wider spectral range than ordinary glass, extending from the visible further into both the UV and IR ranges, and is sometimes used where transparency to these wavelengths is necessary. Fused quartz is used for high-temperature applications such as furnace tubes, lighting tubes, melting crucibles, etc. However, its high melting temperature (1723 °C) and viscosity make it difficult to work with. Therefore, normally, other substances (fluxes) are added to lower
7714-525: Is Blanquette de Limoux , which was invented by Benedictine monks in the Abbey of Saint-Hilaire , near Carcassonne , in 1531. They achieved this by bottling the wine before the initial fermentation had ended. Over a century later, the English scientist and physician Christopher Merret documented the addition of sugar to a finished wine to create a second fermentation six years before Dom Pérignon set foot in
7917-554: Is Hauersekt . German production of sparkling wines dates back to 1826, when G. C. Kessler & Co. was founded in Esslingen am Neckar by Georg Christian Kessler (1787–1842), who had previously worked at the Champagne house Veuve Clicquot from 1807 to 1826. The names used by the German producers for their sparkling wines in the 19th century were "Mousseux", "Sect" or "Champagne" (or Champagner ), although "Sekt" already appears as
8120-418: Is 3.25 × 10 /°C as compared to about 9 × 10 /°C for a typical soda–lime glass ). They are, therefore, less subject to stress caused by thermal expansion and thus less vulnerable to cracking from thermal shock . They are commonly used for e.g. labware , household cookware , and sealed beam car head lamps . The addition of lead(II) oxide into silicate glass lowers the melting point and viscosity of
8323-492: Is a German term for some sparkling wine. The majority of Sekt produced (around 95%) is made by the Charmat method with the remaining premium Sekt being made according to the méthode traditionnelle . Cheap sparkling wine made with CO 2 injection must not be called Sekt, but rather Schaumwein (German for sparkling wine, literally "foam wine"), while semi-sparkling wine is called Perlwein . According to CJEU (Court of Justice of

8526-552: Is a common volcanic glass with high silica (SiO 2 ) content formed when felsic lava extruded from a volcano cools rapidly. Impactite is a form of glass formed by the impact of a meteorite , where Moldavite (found in central and eastern Europe), and Libyan desert glass (found in areas in the eastern Sahara , the deserts of eastern Libya and western Egypt ) are notable examples. Vitrification of quartz can also occur when lightning strikes sand , forming hollow, branching rootlike structures called fulgurites . Trinitite
8729-714: Is a glassy residue formed from the desert floor sand at the Trinity nuclear bomb test site. Edeowie glass , found in South Australia , is proposed to originate from Pleistocene grassland fires, lightning strikes, or hypervelocity impact by one or several asteroids or comets . Naturally occurring obsidian glass was used by Stone Age societies as it fractures along very sharp edges, making it ideal for cutting tools and weapons. Glassmaking dates back at least 6000 years, long before humans had discovered how to smelt iron. Archaeological evidence suggests that
8932-418: Is a very powerful colouring agent, yielding dark green. Sulphur combined with carbon and iron salts produces amber glass ranging from yellowish to almost black. A glass melt can also acquire an amber colour from a reducing combustion atmosphere. Cadmium sulfide produces imperial red , and combined with selenium can produce shades of yellow, orange, and red. Addition of copper(II) oxide (CuO) produces
9135-449: Is achieved by homogenizing the raw materials mixture ( glass batch ), stirring the melt, and crushing and re-melting the first melt. The obtained glass is usually annealed to prevent breakage during processing. Colour in glass may be obtained by addition of homogenously distributed electrically charged ions (or colour centres ). While ordinary soda–lime glass appears colourless in thin section, iron(II) oxide (FeO) impurities produce
9338-403: Is aged for nine months. As noted above, the designation Crémant was previously used for sparkling wines from the Champagne region which were produced with slightly less carbon dioxide and somewhat lower bottle pressure (typically 2–3 atmospheres instead of 5–6). These wines were rare in comparison to regular, full-pressure Champagne. The Crémant designation was also used for sparkling wines from
9541-676: Is extensively used for fibreglass , used for making glass-reinforced plastics (boats, fishing rods, etc.), top-of-stove cookware, and halogen bulb glass. The addition of barium also increases the refractive index. Thorium oxide gives glass a high refractive index and low dispersion and was formerly used in producing high-quality lenses, but due to its radioactivity has been replaced by lanthanum oxide in modern eyeglasses. Iron can be incorporated into glass to absorb infrared radiation, for example in heat-absorbing filters for movie projectors, while cerium(IV) oxide can be used for glass that absorbs ultraviolet wavelengths. Fluorine lowers
9744-473: Is home to the largest segment of Italian sparkling wine production. Made predominately from Chardonnay and Pinot bianco , sparkling wine labeled under the Franciacorta DOCG is permitted to include no more than 15% Pinot nero. Both vintage and non-vintage Franciacorta sparkling wines are made which require 30 and 18 months, respectively, of aging on the lees. Franciacorta Satèn, a Blanc de blancs ,
9947-455: Is in widespread use in optical systems due to its ability to refract, reflect, and transmit light following geometrical optics . The most common and oldest applications of glass in optics are as lenses , windows , mirrors , and prisms . The key optical properties refractive index , dispersion , and transmission , of glass are strongly dependent on chemical composition and, to a lesser degree, its thermal history. Optical glass typically has
10150-489: Is incorrect, as once solidified, glass stops flowing. The sags and ripples observed in old glass were already there the day it was made; manufacturing processes used in the past produced sheets with imperfect surfaces and non-uniform thickness (the near-perfect float glass used today only became widespread in the 1960s). A 2017 study computed the rate of flow of the medieval glass used in Westminster Abbey from
10353-630: Is made at least partially from imported wines from Italy , Spain and France . Sekt labeled as Deutscher Sekt is made exclusively from German grapes, and Sekt b.A. ( bestimmter Anbaugebiete , in parallel to Qualitätswein b.A. ) only from grapes from one of the 13 quality wine regions in Germany. Some of the premium wines are often made using the Riesling , Pinot blanc , Pinot gris and Pinot noir grapes, with much of it drunk locally rather than exported. These Sekts are usually vintage dated with

#173280226237710556-503: Is of Champagne"). The name is still used today for some brands of sparkling wines produced in former Soviet republics, such as Sovetskoye Shampanskoye and Rossiyskoe Shampanskoe . In 2021, Russia banned the use of the designation шампанское for imported sparkling wine, including sparkling wine produced in the Champagne wine region, reserving the designation for domestically produced sparkling wine only. Formerly known as méthode champenoise or méthode classique , champagne
10759-436: Is often used to fill out the remaining parts of the blend. The Languedoc wine Crémant de Limoux is produced in the forty one villages around the village of Limoux in the south of France. The wine is composed primarily of the indigenous grape Mauzac with some Chenin blanc and Chardonnay. The wine must spend a minimum of nine months aging on its lees. The sparkling Blanquette de Limoux is composed predominately of Mauzac and
10962-480: Is one of the first known accounts of understanding the process of sparkling wine and even suggests that British merchants were producing "sparkling Champagne" before the French Champenois were deliberately making it. Fully sparkling wines, such as Champagne, are generally sold with 5 to 6 standard atmospheres (73 to 88 psi ; 510 to 610 kPa ) of pressure in the bottle. This is more than twice
11165-404: Is perhaps the imperial pint (56.8 cL) bottle made between 1874 and 1973 for the English market by Pol Roger , often associated with Sir Winston Churchill . In 2009, a bottle of 1825 Perrier-Jouët Champagne was opened at a ceremony attended by twelve of the world's top wine tasters. This bottle was officially recognised by Guinness World Records as the oldest bottle of Champagne in
11368-401: Is produced by a traditional method. After primary fermentation and bottling, a second alcoholic fermentation occurs in the bottle. This second fermentation is induced by adding several grams of yeast Saccharomyces cerevisiae and rock sugar to the bottle – although each brand has its own secret recipe. According to the appellation d'origine contrôlée a minimum of one and a half years
11571-901: Is produced by forcing molten glass through a fine mesh by centripetal force and breaking the extruded glass fibres into short lengths using a stream of high-velocity air. The fibres are bonded with an adhesive spray and the resulting wool mat is cut and packed in rolls or panels. Besides common silica-based glasses many other inorganic and organic materials may also form glasses, including metals , aluminates , phosphates , borates , chalcogenides , fluorides , germanates (glasses based on GeO 2 ), tellurites (glasses based on TeO 2 ), antimonates (glasses based on Sb 2 O 3 ), arsenates (glasses based on As 2 O 3 ), titanates (glasses based on TiO 2 ), tantalates (glasses based on Ta 2 O 5 ), nitrates , carbonates , plastics , acrylic , and many other substances. Some of these glasses (e.g. Germanium dioxide (GeO 2 , Germania), in many respects
11774-523: Is produced in varying levels of dryness of the wine which are: brut nature, brut (extra dry), seco (dry), semiseco (medium) and dulce (sweet). Under Spanish denominación de origen laws, Cava can be produced in six wine regions and must be made according to the Traditional Method with second fermentation in the bottle and uses a selection of the grapes Macabeu , Parellada , Xarel·lo , Chardonnay , Pinot noir , and Subirat . Despite being

Trento DOC is an appellation for white and rosé sparkling wines made according to the méthode traditionnelle. Chardonnay, Pinot noir, Pinot blanc and Pinot Meunier grapes are used. There is a maximum vine yield of 150 q.l. per hectare for all varietals, and a maximum grape yield of 70%. The wines must rest for
12180-412: Is required to completely develop all the flavour. For years where the harvest is exceptional, a millésime is declared and some champagne will be made from and labelled as the products of a single vintage ( vintage champagne ) rather than a blend of multiple years' harvests. This means that the champagne will be very good and has to mature for at least three years. During this time the champagne bottle
12383-652: Is responsible for about 8% of worldwide sparkling wine production with many other regions emulating the "Champagne style" in both grapes used (generally Chardonnay , Pinot noir and Pinot Meunier ) and production methods—sometimes referred to as the "Champagne method". French sparkling wines made according to the Champagne method of fermentation in the bottle, but sometimes use different grape varieties, are known as Crémants and are governed under their own Appellation d'origine contrôlée (AOC) regulations. Another style of sparkling wine found in France are those made according to

#173280226237712586-457: Is sealed with a crown cap similar to that used on beer bottles. After aging, the bottle is manipulated, either manually or mechanically, in a process called remuage (or "riddling" in English), so that the lees settle in the neck of the bottle. After chilling the bottles, the neck is frozen, and the cap removed. This process is called disgorgement. The six-bar (600 kPa) pressure in

It is planned that the majority of the bottles will be sold at auction, the price of each estimated to be in the region of £40,000–70,000. In April 2015, nearly five years after the bottles were first found, researchers led by Philippe Jeandet,
12992-461: Is stronger than most metals, with a theoretical tensile strength for pure, flawless glass estimated at 14 to 35 gigapascals (2,000,000 to 5,100,000 psi) due to its ability to undergo reversible compression without fracture. However, the presence of scratches, bubbles, and other microscopic flaws lead to a typical range of 14 to 175 megapascals (2,000 to 25,400 psi) in most commercial glasses. Several processes such as toughening can increase
13195-408: Is sufficiently rapid (relative to the characteristic crystallization time) then crystallization is prevented and instead, the disordered atomic configuration of the supercooled liquid is frozen into the solid state at T g . The tendency for a material to form a glass while quenched is called glass-forming ability. This ability can be predicted by the rigidity theory . Generally, a glass exists in
13398-414: Is taken to avoid tannins and other phenolic compounds with many premium producers still choosing to harvest by hand rather than risk mechanical harvesting which may split the berries and encourage maceration between the skins and juice. The press house is often close by the vineyard to where the grapes can be quickly pressed and separated from their skins. Red wine grapes like Pinot noir can be used in
13601-545: Is the cheapest and lowest level of sparkling wine, made by injecting the wine with CO 2 . Top-quality Espumantes can be found in Bairrada region and in Távora-Varosa sub region – Murganheira is an example of high-quality Espumante from this region. According to etymological sources, the term spumante was not used in a wine context until 1908, more than 40 years following the first Italian sparkling wine using
13804-583: Is the name of a type of Spanish (mostly in Catalonia but also in other regions such as Valencia , La Rioja , Aragon , Extremadura ) white or pink sparkling wine produced mainly in the Alto Penedés in Catalonia, 40 km to the south west of Barcelona, with the méthode champenoise but grape varieties different from grapes used in Champagne making. Cava is a Greek term that was used to refer to
14007-427: Is through the initiation of a secondary fermentation that distinguishes sparkling wine production and gives the wine its characteristic bubbles. One of the by-products of fermentation is the creation of carbon dioxide gas. While this is able to be released during the first fermentation, efforts are taken during the second fermentation to retain the gas and have it dissolve into the wine. This creates high pressure within
14210-436: Is transparent, easily formed, and most suitable for window glass and tableware. However, it has a high thermal expansion and poor resistance to heat. Soda–lime glass is typically used for windows , bottles , light bulbs , and jars . Borosilicate glasses (e.g. Pyrex , Duran ) typically contain 5–13% boron trioxide (B 2 O 3 ). Borosilicate glasses have fairly low coefficients of thermal expansion (7740 Pyrex CTE
14413-424: Is typically drunk during celebrations. For example, British Prime Minister Tony Blair held a champagne reception to celebrate London winning the right to host the 2012 Summer Olympics . It is also used to launch ships when a bottle is smashed over the hull during the ship's launch. If the bottle fails to break this is often thought to be bad luck. Champagne is a single appellation d'origine contrôlée but
14616-582: Is used to adjust the sweetness level of the wine after it has been disgorged. In the methode ancestrale (ancestral method), the disgorgement step is skipped and the wine is sold with the lees still present as sediment in the wine. In the transfer method , after the wines have gone through the traditional method including riddling and disgorgement, the bottles are emptied into a large tank where they are then transferred to small and large format wine bottles such as 3 litre jeroboam and small split sizes used on airlines. Numerous quality producers worldwide use
14819-437: Is used to fine tune the perception of acidity in the wine. For Caroline Latrive, cellar master of Ayala, a Champagne house that pioneered drier champagnes at the end of the 19th century, dosage represents the final touch in champagne making and must be as subtle as possible to bring the right balance. Additionally, dosage protects champagne from oxidation because it includes a small amount of SO 2 , and sugar also acts as
15022-541: Is usually either white or rosé , but there are examples of red sparkling wines such as the Italian Brachetto , Bonarda and Lambrusco , and the Australian sparkling Shiraz . The sweetness of sparkling wine can range from very dry brut styles to sweeter doux varieties (French for 'hard' and 'soft', respectively). The sparkling quality of these wines comes from its carbon dioxide content and may be
15225-467: The Côte de Beaune . The various terroirs account for the differences in grape characteristics and explain the appropriateness of blending juice from different grape varieties and geographical areas within Champagne, to get the desired style for each Champagne house. Most of the Champagne produced today is "Non- vintage ", meaning that it is a blended product of grapes from multiple vintages. Most of
15428-589: The Institut national de l'origine et de la qualité (formerly the Institut National des Appellations d'Origine , INAO). In 2007, the INAO , the government organization that controls wine appellations in France, was preparing to make the largest revision of the region's legal boundaries since 1927 in response to economic pressures. With soaring demand and limited production of grapes, Champagne houses say
15631-402: The methode ancestrale which skips the process of disgorgement and produces wines with slight sweetness and still containing the particles of dead yeast matter in the form of lees in the bottle. The regions of Gaillac , Limoux and Clairette de Die are the most well-known producers of methode ancestrale wines. Champagne is produced at the far extreme of viticultural circumstances, where
15834-492: The Abbey of Hautvillers . Merret presented a paper at the Royal Society , in which he detailed what is now called méthode traditionnelle , in 1662. Merret's discoveries coincided also with English glass -makers' technical developments that allowed bottles to be produced that could withstand the required internal pressures during secondary fermentation. French glass-makers at this time could not produce bottles of
16037-524: The Late Bronze Age , there was a rapid growth in glassmaking technology in Egypt and Western Asia . Archaeological finds from this period include coloured glass ingots , vessels, and beads. Much early glass production relied on grinding techniques borrowed from stoneworking , such as grinding and carving glass in a cold state. The term glass has its origins in the late Roman Empire , in
16240-706: The Muscat grape uses the DOCG Asti and from the Glera grape the DOC Prosecco . In Germany, Sekt is a common sparkling wine. Other French wine regions cannot use the name Champagne: e.g., Burgundy and Alsace produce Crémant . In 2008, more than 3,000 bottles of sparkling wine produced in California labelled with the term "Champagne" were destroyed by Belgian government authorities. Regardless of
16443-535: The Renaissance period in Europe, the use of large stained glass windows became much less prevalent, although stained glass had a major revival with Gothic Revival architecture in the 19th century. During the 13th century, the island of Murano , Venice , became a centre for glass making, building on medieval techniques to produce colourful ornamental pieces in large quantities. Murano glass makers developed
16646-537: The Roman glass making centre at Trier (located in current-day Germany) where the late-Latin term glesum originated, likely from a Germanic word for a transparent , lustrous substance. Glass objects have been recovered across the Roman Empire in domestic, funerary , and industrial contexts, as well as trade items in marketplaces in distant provinces. Examples of Roman glass have been found outside of
16849-443: The Royal Society show. Dom Pérignon was originally charged by his superiors at the Abbey of Hautvillers to get rid of the bubbles since the pressure in the bottles caused many of them to burst in the cellar. As sparkling wine production increased in the early 18th century, cellar workers had to wear a heavy iron mask to prevent injury from spontaneously bursting bottles. The disturbance caused by one bottle exploding could cause
17052-465: The dielectric constant of glass. Fluorine is highly electronegative and lowers the polarizability of the material. Fluoride silicate glasses are used in the manufacture of integrated circuits as an insulator. Glass-ceramic materials contain both non-crystalline glass and crystalline ceramic phases. They are formed by controlled nucleation and partial crystallisation of a base glass by heat treatment. Crystalline grains are often embedded within
17255-436: The glass batch preparation and mixing, the raw materials are transported to the furnace. Soda–lime glass for mass production is melted in glass-melting furnaces . Smaller-scale furnaces for speciality glasses include electric melters, pot furnaces, and day tanks. After melting, homogenization and refining (removal of bubbles), the glass is formed . This may be achieved manually by glassblowing , which involves gathering
17458-442: The grape struggles to ripen in a long drawn out growing season. Cool climate weather limits the varieties of grape, and the types of wine that can be made, but it is in this region that sparkling wine has found its standard bearer. The limestone – chalk soil produces grapes that have a certain balance of acidity, extract and richness that is difficult to replicate in other parts of the world. The Champenois vigorously defend use of
17661-519: The méthode champenoise produced by Carlo Gancia which was then sold as "Moscato Champagne". Sparkling wines are made throughout Italy but the Italian sparkling wines most widely seen on the world market are the Prosecco from Veneto , Franciacorta from Lombardy , Asti from Piedmont and Lambrusco from Emilia . The Trento DOC is also famous. Though Franciacorta wines are made according to
17864-411: The "Traditional" method to make their sparkling wines. The Charmat method takes place in stainless steel fermentation tanks that are pressurized. The fresh yeast and sugar mixture is added to the wine which rapidly stimulates fermentation in the pressurized environment. The wine is then cooled, clarified , and bottled using a counter pressure filler. The process of carbon injection (or carbonation),
18067-510: The 10th century onwards, glass was employed in stained glass windows of churches and cathedrals , with famous examples at Chartres Cathedral and the Basilica of Saint-Denis . By the 14th century, architects were designing buildings with walls of stained glass such as Sainte-Chapelle , Paris, (1203–1248) and the East end of Gloucester Cathedral . With the change in architectural style during
18270-439: The 17th, 18th, and 19th centuries. The leading manufacturers made efforts to associate their Champagnes with nobility and royalty through advertising and packaging, which led to its popularity among the emerging middle class . Still wines from the Champagne region were known before medieval times. The Romans were the first to plant vineyards in this area of northeast France, with the region being tentatively cultivated by
18473-461: The 1930s, which later became known as Depression glass . In the 1950s, Pilkington Bros. , England , developed the float glass process, producing high-quality distortion-free flat sheets of glass by floating on molten tin . Modern multi-story buildings are frequently constructed with curtain walls made almost entirely of glass. Laminated glass has been widely applied to vehicles for windscreens. Optical glass for spectacles has been used since
18676-451: The 5th century. Cultivation was initially slow due to the unpopular edict by Emperor Domitian that all colonial vines must be uprooted. When Emperor Probus , the son of a gardener, rescinded the edict, a temple to Bacchus was erected, and the region started to produce a light, fruity, red wine that contrasted with heavier Italian brews often fortified with resin and herbs. Later, church owned vineyards , and monks produced wine for use in
18879-545: The Alentejo, known for its extreme temperatures and arid climate. While Spain has one regulating body, DOC Cava, spread across several different political regions, quality Espumante is produced solely in DOC Bairrada, located just south of Vinho Verde. In order for a wine to be certified as a quality Espumante from DOC Bairrada, it must be made in the traditional champagne (indicating the year of harvest) and stamped with
19082-605: The Apennine side of the Po Valley. Notable wines include Brachetto and Lambrusco . Also very well known and with rich tradition are Gutturnio , Bonarda and sparkling Barbera ; in central Italy, lesser known Red Vernaccia produces semi-sweet sparkling reds. In Australia , red sparkling wines are often made from the Shiraz grape. The viticultural and winemaking practices of making sparkling wine have many similarities to
19285-628: The Champagne region, such as Blanquette de Limoux produced in Southern France. Sparkling wines are produced around the world, and are often referred to by their local name or region, such as Prosecco , Franciacorta , Trento DOC , Oltrepò Pavese Metodo Classico and Asti from Italy (the generic Italian term for sparkling wine being spumante ), Espumante from Portugal, Cava from Spain, and Cap Classique from South Africa. Sparkling wines have been produced in Central and Eastern Europe since
19488-637: The European Union) regulation, Sekt and the Term „Qualitätsschaumwein“ (German for quality sparkling wine) are the same. Quality sparkling wine is defined by means of precise specifications, including at least 10 per cent alcohol content and 3 bars (44 psi) pressure in the bottle, among other things. For quality sparkling wines PSR (produced in specified regions), additional geographical regions (storage sparkling wine) and vintage specifications (vintage sparkling wine) are permitted. Around 90 percent of Sekt
19691-516: The Loire valley, in the form of Crémant de Saumur and Crémant de Vouvray , without being defined as separate appellations. In 1975, Crémant de Loire was given formal recognition as an AOC, and was followed by Crémant de Bourgogne (1975) and Crémant d'Alsace (1976). When in the late 1980s lobbying by Champagne producers led to méthode champenoise being forbidden within the European Union as
19894-687: The Middle Ages. The production of lenses has become increasingly proficient, aiding astronomers as well as having other applications in medicine and science. Glass is also employed as the aperture cover in many solar energy collectors. In the 21st century, glass manufacturers have developed different brands of chemically strengthened glass for widespread application in touchscreens for smartphones , tablet computers , and many other types of information appliances . These include Gorilla Glass , developed and manufactured by Corning , AGC Inc. 's Dragontrail and Schott AG 's Xensation. Glass
20097-543: The Pb ion renders it highly immobile and hinders the movement of other ions; lead glasses therefore have high electrical resistance, about two orders of magnitude higher than soda–lime glass (10 vs 10 Ω⋅cm, DC at 250 °C). Aluminosilicate glass typically contains 5–10% alumina (Al 2 O 3 ). Aluminosilicate glass tends to be more difficult to melt and shape compared to borosilicate compositions but has excellent thermal resistance and durability. Aluminosilicate glass
20300-533: The UK's Pilkington Brothers, who created a continuous ribbon of glass using a molten tin bath on which the molten glass flows unhindered under the influence of gravity. The top surface of the glass is subjected to nitrogen under pressure to obtain a polished finish. Container glass for common bottles and jars is formed by blowing and pressing methods. This glass is often slightly modified chemically (with more alumina and calcium oxide) for greater water resistance. Once
20503-566: The VEQPRD (Vinho Espumante de Qualidade Produzido em Região Determinada) certification. VFQPRD is a regional sparkling wine made in the traditional champagne, charmat or transfer method in one of the following determined regions: Douro , Ribatejo , Minho , Alentejo or Estremadura . VQPRD is a sparkling wine that can be made by injecting the wine with gas in the traditional champagne, charmat, transfer method anywhere in Portugal. Espumoso
20706-719: The action of water, making it an ideal material for the manufacture of containers for foodstuffs and most chemicals. Nevertheless, although usually highly resistant to chemical attack, glass will corrode or dissolve under some conditions. The materials that make up a particular glass composition affect how quickly the glass corrodes. Glasses containing a high proportion of alkali or alkaline earth elements are more susceptible to corrosion than other glass compositions. The density of glass varies with chemical composition with values ranging from 2.2 grams per cubic centimetre (2,200 kg/m ) for fused silica to 7.2 grams per cubic centimetre (7,200 kg/m ) for dense flint glass. Glass
20909-449: The assembled product of several vineyards and vintages. In Champagne there are over 19,000 vineyard owners, only 5,000 of which are owned by Champagne producers. The rest sell their grapes to the various Champagne houses, négociants and co-operatives. The grapes, most commonly Chardonnay, Pinot noir and Pinot meunier, are used to make several base wines that are assembled together to make Champagne. Each grape adds its own unique imprint to
21112-480: The auspices of the Comité Interprofessionnel du vin de Champagne (CIVC), has developed a comprehensive set of rules and regulations for all wine produced in the region to protect its economic interests. They include codification of the most suitable growing places, the most suitable grape types (most Champagne is a blend of up to three grape varieties, though other varieties are allowed ), and
21315-444: The average size and consistency of the bubbles, can vary depending on the quality of the wine and the type of glass used. According to the wine academic Graham Harding, the average bottle of champagne contains enough carbon dioxide to potentially produce 49 million bubbles. Wine expert Tom Stevenson puts the number at 250 million. The bubbles initially form at 20 micrometers in diameter and expand as they gain buoyancy and rise to
21518-434: The base will be from a single year vintage with producers blending anywhere from 10 to 15% (even as high as 40%) of wine from older vintages. If the conditions of a particular vintage are favourable, some producers will make a vintage wine, which must be composed entirely of grapes from that vintage year. Under Champagne wine regulations, houses that make both vintage and non-vintage wines are allowed to use no more than 80% of
21721-430: The base wines are then blended to form a cuvée . While there are examples of varietal sparkling wines, such as blanc de blancs (white of whites) made from 100% Chardonnay , most sparkling wines are blends of several grape varieties, vineyards and vintages . Producers with wide access to grapes will use wines from several hundred base wines to create a blend that reflect the "house style" of their non-vintage wine. It
21924-544: The beginning of its second fermentation. Sizes larger than Jeroboam (3 L) are rare. Primat bottles (27 L)—and, as of 2002, Melchizedek bottles (30 L)—are exclusively offered by the House Drappier . (The same names are used for bottles containing regular wine and port; however, Jeroboam , Rehoboam , and Methuselah refer to different bottle volumes.) Unique sizes have been made for specific markets, special occasions and people. The most notable example
22127-451: The beginning of the Belle Époque period, champagne has gone from a regional product serving a niche market to a national commodity which is distributed globally. The popularity of champagne is particularly attributed to the success of champagne producers in marketing the wine's image as a royal and aristocratic drink. Laurent-Perrier 's advertisements in late 1890 boasted their champagne was
22330-435: The bottle forces out the ice containing the lees. Some wine from previous vintages and additional sugar ( le dosage ) is added to maintain the level within the bottle and adjust the sweetness of the finished wine. The bottle is then quickly corked to maintain the carbon dioxide in solution. An initial burst of effervescence occurs when the champagne contacts the dry glass on pouring. These bubbles form on imperfections in
22533-443: The bottle. Over time, their compressed shape becomes more permanent and the distinctive "mushroom" shape becomes more apparent. Sparkling wine Sparkling wine is a wine with significant levels of carbon dioxide in it, making it fizzy. While it is common to refer to this as champagne , European Union countries legally reserve that word for products exclusively produced in the Champagne region of France. Sparkling wine
22736-512: The champagne houses catered to political interest such as the labels that appeared on different brands on bottles commemorating the centennial anniversary of the French Revolution of 1789. On some labels there were flattering images of Marie Antoinette that appealed to the conservative factions of French citizens that viewed the former queen as a martyr. On other labels there were stirring images of Revolutionary scenes that appealed to
22939-506: The city of Saumur and are a blend of the Chardonnay , Chenin blanc and Cabernet franc . AOC laws do allow cuvées with Sauvignon blanc , Cabernet Sauvignon , Pinot noir , Gamay , Côt , Pineau d'aunis and Grolleau but those grapes are rarely used in a significant amount. In Burgundy , AOC laws require that Crémant de Bourgogne be composed of at least thirty percent Pinot noir, Chardonnay, Pinot blanc or Pinot gris . Aligoté
23142-416: The corks from blowing out. Initial versions were difficult to apply and inconvenient to remove. Even when it was deliberately produced as a sparkling wine, champagne was for a very long time made by the méthode rurale , where the wine was bottled before the initial fermentation had finished. Champagne did not use the méthode champenoise until the 19th century, about 200 years after Merret documented
23345-411: The cost factor has a low priority. In the laboratory mostly pure chemicals are used. Care must be taken that the raw materials have not reacted with moisture or other chemicals in the environment (such as alkali or alkaline earth metal oxides and hydroxides, or boron oxide ), or that the impurities are quantified (loss on ignition). Evaporation losses during glass melting should be considered during
23548-427: The crystalline ceramic phase can be balanced with the positive CTE of the glassy phase. At a certain point (~70% crystalline) the glass-ceramic has a net CTE near zero. This type of glass-ceramic exhibits excellent mechanical properties and can sustain repeated and quick temperature changes up to 1000 °C. Fibreglass (also called glass fibre reinforced plastic, GRP) is a composite material made by reinforcing
23751-439: The designation Crémant in their name: There are also Crémant designations outside France: French appellation laws dictate that a Crémant must be harvested by hand with yields not exceeding a set amount for their AOC . The wines must also be aged for a minimum of one year. The Loire Valley is France's largest producer of sparkling wines outside of the Champagne region. The majority of these Crémant de Loire are produced around
23954-683: The desired form is obtained, glass is usually annealed for the removal of stresses and to increase the glass's hardness and durability. Surface treatments, coatings or lamination may follow to improve the chemical durability ( glass container coatings , glass container internal treatment ), strength ( toughened glass , bulletproof glass , windshields ), or optical properties ( insulated glazing , anti-reflective coating ). New chemical glass compositions or new treatment techniques can be initially investigated in small-scale laboratory experiments. The raw materials for laboratory-scale glass melts are often different from those used in mass production because
24157-664: The driest English is close to contemporary tastes. Champagne is mostly fermented in two sizes of bottles, standard bottles (750 millilitres) and magnums (1.5 litres). In general, magnums are thought to be higher quality, as there is less oxygen in the bottle, and the volume–to–surface-area ratio favours the creation of appropriately sized bubbles. However, there is no hard evidence for this view. Other bottle sizes, mostly named for Biblical figures, are generally filled with Champagne that has been fermented in standard bottles or magnums. Gosset still bottles its Grande Réserve in Jeroboam from
24360-630: The earliest records of viticulture dated to 1657. In 1999, in an accord with the EU, the Swiss government conceded that, by 2004, the village would phase out the use of the name. Sales dropped from 110,000 bottles a year to 32,000 after the change. In April 2008, the villagers resolved to fight against the restriction following a Swiss open-air vote. In the Soviet Union , all sparkling wines were called шампанское ( shampanskoe , Russian for "that, which
24563-471: The early 18th century, cellar workers would still have to wear a heavy iron mask that resembled a baseball catcher's mask to prevent injury from spontaneously bursting bottles. The disturbance caused by one bottle's disintegration could cause a chain reaction, with it being routine for cellars to lose 20–90% of their bottles to instability. The mysterious circumstance surrounding the then unknown process of fermentation and carbonic gas caused some critics to call
24766-538: The early 19th-century. "Champagne" was further popularised in the region, late in the century, when József Törley started production in Hungary using French methods, learned as an apprentice in Reims . Törley has since become one of the largest European producers of sparkling wine. The United States is a significant producer of sparkling wine today, with producers in numerous states. Recently, production of sparkling wine
24969-466: The exceptionally clear colourless glass cristallo , so called for its resemblance to natural crystal, which was extensively used for windows, mirrors, ships' lanterns, and lenses. In the 13th, 14th, and 15th centuries, enamelling and gilding on glass vessels were perfected in Egypt and Syria. Towards the end of the 17th century, Bohemia became an important region for glass production, remaining so until
25172-554: The far extremes of sustainable viticulture , the grapes would struggle to ripen fully and often would have bracing levels of acidity and low sugar levels . The wines would be lighter bodied and thinner than the Burgundy wines they sought to outdo. Contrary to legend and popular assumption, Dom Pérignon did not invent sparkling wine, though he did make important contributions to the production and quality of both still and sparkling Champagne wines. The oldest recorded sparkling wine
25375-421: The favourite of Leopold II of Belgium , George I of Greece , Alfred, Duke of Saxe-Coburg and Gotha , Margaret Cambridge, Marchioness of Cambridge , and John Lambton, 3rd Earl of Durham , among other nobles, knights, and military officers. Despite this royal prestige, champagne houses also portrayed champagne as a luxury which could be enjoyed by anyone, and was fit for any occasion. This strategy worked, and, by
25578-440: The fermentation process would restart when the weather warmed and the cork-stoppered wine would begin to build pressure from carbon dioxide gas. When the wine was opened, it would be bubbly. In 1662, the English scientist Christopher Merret presented a paper detailing how the presence of sugar in a wine led to it eventually sparkling and that by adding sugar to a wine before bottling it, nearly any wine could be made to sparkle. This
25781-403: The first publicly available prestige cuvée was Moët & Chandon's Dom Pérignon, launched in 1936 with the 1921 vintage. Until then, Champagne houses produced different cuvées of varying quality, but a top-of-the-range wine produced to the highest standards (and priced accordingly) was a new idea. In fact, Louis Roederer had been producing Cristal since 1876, but this was strictly for
25984-459: The first true synthetic glass was made in Lebanon and the coastal north Syria , Mesopotamia or ancient Egypt . The earliest known glass objects, of the mid-third millennium BC, were beads , perhaps initially created as accidental by-products of metalworking ( slags ) or during the production of faience , a pre-glass vitreous material made by a process similar to glazing . Early glass
26187-754: The former Roman Empire in China , the Baltics , the Middle East , and India . The Romans perfected cameo glass , produced by etching and carving through fused layers of different colours to produce a design in relief on the glass object. In post-classical West Africa, Benin was a manufacturer of glass and glass beads. Glass was used extensively in Europe during the Middle Ages . Anglo-Saxon glass has been found across England during archaeological excavations of both settlement and cemetery sites. From
26390-408: The gentle pressing of the grapes and absence of skin contact during fermentation, usually also yield a white base wine. Most Champagnes, including Rosé wines, are made from a blend of all three grapes, although blanc de blancs ("white from whites") Champagnes are made from 100% Chardonnay and blanc de noirs ("white from blacks") Champagnes are made solely from Pinot noir, Pinot meunier or
26593-555: The glass and melt phases. Important polymer glasses include amorphous and glassy pharmaceutical compounds. These are useful because the solubility of the compound is greatly increased when it is amorphous compared to the same crystalline composition. Many emerging pharmaceuticals are practically insoluble in their crystalline forms. Many polymer thermoplastics familiar to everyday use are glasses. For many applications, like glass bottles or eyewear , polymer glasses ( acrylic glass , polycarbonate or polyethylene terephthalate ) are
26796-420: The glass that facilitate nucleation or, to a minimal extent, on cellulose fibres left over from the wiping and drying process as shown with a high-speed video camera . However, after the initial rush, these naturally occurring imperfections are typically too small to consistently act as nucleation points as the surface tension of the liquid smooths out these minute irregularities. The nucleation sites that act as
26999-407: The glass that facilitate nucleation . Nucleations are needed to stimulate the formation of bubbles because carbon dioxide has first to diffuse from the wine solution before it can rise out of the glass and into the air. A poured glass of sparkling wine will lose its bubbliness and carbon dioxide gas much more quickly than an open bottle alone would. The frothiness or "mousse" of the wine, along with
27202-493: The glass transition range. The glass transition may be described as analogous to a second-order phase transition where the intensive thermodynamic variables such as the thermal expansivity and heat capacity are discontinuous. However, the equilibrium theory of phase transformations does not hold for glass, and hence the glass transition cannot be classed as one of the classical equilibrium phase transformations in solids. Glass can form naturally from volcanic magma. Obsidian
27405-406: The glass transition temperature is not supported by empirical research or theoretical analysis (see viscosity in solids ). Though atomic motion at glass surfaces can be observed, and viscosity on the order of 10 –10 Pa s can be measured in glass, such a high value reinforces the fact that glass would not change shape appreciably over even large periods of time. For melt quenching, if the cooling
27608-464: The grapes have the complexity and richness to warrant it. Sparkling wines designated Crémant ("creamy") were originally named because their lower carbon dioxide pressures were thought to give them a creamy rather than fizzy mouth-feel. Though they may have full pressures today, they are still produced using the traditional method , and have to fulfill strict production criteria. In France, there are eight appellations for sparkling wine which include
27811-412: The group that had the sparkling wine had 54 milligrams of alcohol in their blood while the group that had the same sparkling wine, only flat, had 39 milligrams. Putting a spoon in an open bottle of sparkling wine to keep it bubbly is a myth. A proper stopper is much more effective. The amount of sugar (dosage) added after the second fermentation and aging varies and will dictate the sweetness level of
28014-437: The late 18th century; storied French Champagne houses Rinault and Veuve Clicquot have each claimed to have shipped and sold the first bottles. The wine is produced by one of two methods. Using the saignée method, winemakers will leave the clear juice of dark grapes to macerate with the skins for a brief time, resulting in wine lightly colored and flavored by the skins. In the more common d'assemblage method, producers will blend
28217-541: The lead in this area with advertisements touting their wine's favour with the Countess of Dudley , the wife of the 9th Earl of Stamford , the wife of the Baron Tollemache , and the opera singer Adelina Patti . Champagne labels were designed with images of romantic love and marriage as well as other special occasions that were deemed important to women, such as the baptism of a child. In some advertisements,
28420-427: The legal requirements for labeling, extensive education efforts by the Champagne region, and the use of alternative names by non-Champagne sparkling wine producers, some consumers, and wine sellers, including "Korbels California Champagne", use Champagne as a generic term for white sparkling wines, regardless of origin. The village of Champagne, Switzerland has traditionally made a still wine labelled as "Champagne":
28623-473: The liberal left sentiments of French citizens. As World War I loomed, champagne houses put images of soldiers and countries' flags on their bottles, customizing the image for each country to which the wine was imported. During the Dreyfus affair , one champagne house released a champagne antijuif with antisemitic advertisements to take advantage of the wave of Antisemitism that hit parts of France. Champagne
28826-458: The liquid can easily be supercooled into a glass. Examples include LiCl: R H 2 O (a solution of lithium chloride salt and water molecules) in the composition range 4< R <8. sugar glass , or Ca 0.4 K 0.6 (NO 3 ) 1.4 . Glass electrolytes in the form of Ba-doped Li-glass and Ba-doped Na-glass have been proposed as solutions to problems identified with organic liquid electrolytes used in modern lithium-ion battery cells. Following
29029-502: The long-defunct Champagne house Juglar (absorbed into Jacquesson in 1829.) The shipwreck is dated between 1800 and 1830, and the bottles discovered may well predate the 1825 Perrier-Jouët referenced above. When experts were replacing the old corks with new ones, they discovered there were also bottles from a third house, Heidsieck . The wreck, then, contained 95 bottles of Juglar, 46 bottles of Veuve Clicquot , and four bottles of Heidsieck, in addition to 23 bottles whose manufacture
29232-495: The main characters bonding over enjoying the unpopular drink, and caused a sales boost after the film's release. It is also cited by the Eagles as a beverage of choice in the titular " Hotel California ." Rosé Champagnes, particularly brut varieties, began regaining popularity in the late 20th century in many countries. Because of the complex variety of flavors it presents, rosé Champagne is often served in fine dining restaurants, as
29435-622: The material, e.g. "glass" , " glasses ", " magnifying glass ". Glass is most often formed by rapid cooling ( quenching ) of the molten form. Some glasses such as volcanic glass are naturally occurring, and obsidian has been used to make arrowheads and knives since the Stone Age . Archaeological evidence suggests glassmaking dates back to at least 3600 BC in Mesopotamia , Egypt , or Syria . The earliest known glass objects were beads , perhaps created accidentally during metalworking or
29638-481: The melt whilst it floats on a gas stream) or splat quenching (pressing the melt between two metal anvils or rollers), may be used to increase the cooling rate or to reduce crystal nucleation triggers. In the past, small batches of amorphous metals with high surface area configurations (ribbons, wires, films, etc.) have been produced through the implementation of extremely rapid rates of cooling. Amorphous metal wires have been produced by sputtering molten metal onto
29841-433: The melt. The high density of lead glass (silica + lead oxide (PbO) + potassium oxide (K 2 O) + soda (Na 2 O) + zinc oxide (ZnO) + alumina) results in a high electron density, and hence high refractive index, making the look of glassware more brilliant and causing noticeably more specular reflection and increased optical dispersion . Lead glass has a high elasticity, making the glassware more workable and giving rise to
30044-619: The melting temperature and simplify glass processing. Sodium carbonate (Na 2 CO 3 , "soda") is a common additive and acts to lower the glass-transition temperature. However, sodium silicate is water-soluble , so lime (CaO, calcium oxide , generally obtained from limestone ), along with magnesium oxide (MgO), and aluminium oxide (Al 2 O 3 ), are commonly added to improve chemical durability. Soda–lime glasses (Na 2 O) + lime (CaO) + magnesia (MgO) + alumina (Al 2 O 3 ) account for over 75% of manufactured glass, containing about 70 to 74% silica by weight. Soda–lime–silicate glass
30247-410: The metallic ions will absorb wavelengths of light corresponding to specific colours. In the manufacturing process, glasses can be poured, formed, extruded and moulded into forms ranging from flat sheets to highly intricate shapes. The finished product is brittle but can be laminated or tempered to enhance durability. Glass is typically inert, resistant to chemical attack, and can mostly withstand
30450-418: The method used to make soda pop fizzy, does not involve initiating a secondary fermentation but rather injecting carbon dioxide gas directly into the wine. This method produces large bubbles that quickly dissipate and is generally only used in the cheapest sparkling wines. An initial burst of effervescence occurs when the sparkling wine contacts the dry glass on pouring. These bubbles form on imperfections in
30653-409: The most significant architectural innovations of modern times, where glass buildings now often dominate the skylines of many modern cities . These systems use stainless steel fittings countersunk into recesses in the corners of the glass panels allowing strengthened panes to appear unsupported creating a flush exterior. Structural glazing systems have their roots in iron and glass conservatories of
30856-484: The name Crémant. Some of these are exclusively sparkling wine appellations, and some are appellations allowing both still and sparkling wine to be made. The term Mousseux is French for "sparkling" and can refer to a sparkling wine made using methods other than the méthode champenoise such as the Charmat method, while Crémant can only be used for wines that have been made using the méthode champenoise . Sparkling-only are: Either still or sparkling are: Cava
31059-462: The pressure found in an automobile tire . European Union regulations define a sparkling wine as any wine with an excess of 3 atmospheres in pressure. These include German Sekt , Spanish Espumoso , Italian Spumante and French Crémant or Mousseux wines. Semi-sparkling wines are defined as those with between 1 and 2.5 atmospheres of pressures and include German spritzig , Italian frizzante and French pétillant wines. The amount of pressure in
31262-555: The private consumption of the Russian tsar . Cristal was made publicly available with the 1945 vintage. Then came Taittinger 's Comtes de Champagne (first vintage 1952), and Laurent-Perrier 's Grand Siècle 'La Cuvée' in 1960, a blend of three vintages (1952, 1953, and 1955) and Perrier Jouët's La Belle Époque . In the last three decades of the 20th century, most Champagne houses followed these with their own prestige cuvées , often named after notable people with
31465-486: The process. The 19th century saw a dramatic growth in champagne production, going from a regional production of 300,000 bottles a year in 1800 to 20 million bottles in 1850. In 2007, champagne sales hit a record of 338.7 million bottles. In the 19th century, champagne was noticeably sweeter than today's champagnes. The trend towards drier champagne began when Perrier-Jouët decided not to sweeten his 1846 vintage before exporting it to London . The designation Brut Champagne
31668-899: The production criteria. Although such usage is rare, for example in Luxembourg , Crémant de Luxembourg is a designation within the Moselle Luxembourgeoise appellation, rather than a separate appellation, but otherwise follows the same rules as French Crémant. Sula Vineyards produce "Sula Brut Crémant de Nashik" (up To 80% Chenin Blanc, the remainder Riesling and Viognier) and "Sula Brut Tropicale Crémant de Nashik" (60% Chenin Blanc, 40% Shiraz, Viognier) in India, which they differentiate from their "Méthode Classique" and "Méthode Traditionnelle" products. There are also some other French appellations for sparkling wines, which do not carry
31871-922: The production of faience , which is a form of pottery using lead glazes. Due to its ease of formability into any shape, glass has been traditionally used for vessels, such as bowls , vases , bottles , jars and drinking glasses. Soda–lime glass , containing around 70% silica , accounts for around 90% of modern manufactured glass. Glass can be coloured by adding metal salts or painted and printed with vitreous enamels , leading to its use in stained glass windows and other glass art objects. The refractive , reflective and transmission properties of glass make glass suitable for manufacturing optical lenses , prisms , and optoelectronics materials. Extruded glass fibres have applications as optical fibres in communications networks, thermal insulating material when matted as glass wool to trap air, or in glass-fibre reinforced plastic ( fibreglass ). The standard definition of
32074-416: The production of still wine with some noted divergence. At the vineyard, grapes are harvested early when there is still high acid levels . In areas like Australia, winemakers aim to harvest the grapes at 17 to 20° brix (the sugar content of a solution). Unlike still wine production, high sugar levels are not ideal and grapes destined for sparkling wine production may be harvested at higher yields . Care
32277-706: The production of white sparkling wines because their juice is initially clear and is only later tinted red through exposure to the color pigments in grape skins. While some skin exposure may be desirable in the production of rosé sparkling wines and some blanc de noirs (white of blacks), most sparkling wine producers take extended precautions to limit the amount of skin contact. The primary fermentation of sparkling wine begins like most other wines, though winemakers may choose to use specially cultivated sparkling wine yeasts . The wines may go through malolactic fermentation , though producers wishing to make fruitier, simpler wines will usually forgo this step. After fermentation
32480-508: The protection was reaffirmed in the Treaty of Versailles after World War I. Over 70 countries have adopted similar legal protection. Most recently Australia , Chile , Brazil , Canada and China passed laws or signed agreements with Europe that limit the use of the term "Champagne" to only those products produced in the Champagne region. The United States bans the use of all new U.S.-produced wine brands. However, those that had approval to use
32683-686: The region. The type of champagne producer can be identified from the abbreviations followed by the official number on the bottle: In the 19th century, champagne was produced and promoted to mark contemporary political events, such as the Franco-Russian Alliance of 1893, and the Tennis Court Oath to mark the centennial of French Revolution , linking champagne to French nationalist ideology. Négociants also managed to market champagne by identifying it with leisure activities and sporting events. They also successfully appealed to
32886-633: The remaining semi-generic labels as harmful to their reputations (cf. Napa Declaration on Place ). Even the terms méthode champenoise and Champagne method were forbidden by an EU court decision in 1994. As of 2005 the description most often used for sparkling wines using the second fermentation in the bottle process, but not from the Champagne region, is méthode traditionnelle . Sparkling wines are produced worldwide, and many producers use special terms to define them: Spain uses Cava , Italy designates it spumante , and South Africa uses cap classique . An Italian sparkling wine made from
33089-413: The required quality or strength. As early as 1663, the poet Samuel Butler referred to "brisk champagne". In France, the first sparkling champagne was created accidentally; the pressure in the bottle led it to be called "the devil's wine" ( le vin du diable ), as bottles exploded or corks popped. At the time, bubbles were considered a fault. In 1844, Adolphe Jaquesson invented the muselet to prevent
33292-536: The result of natural fermentation , either in a bottle, as with the traditional method , in a large tank designed to withstand the pressures involved (as in the Charmat process ), or as a result of simple carbon dioxide injection in some cheaper sparkling wines. In European Union countries, the word "champagne" is reserved by law only for sparkling wine from the Champagne region of France. The French terms Mousseux and Crémant refer to sparkling wine not made in
33495-419: The result. Chardonnay is prized for its finesse and aging ability . Pinot noir adds body and fruit while Pinot meunier contributes substantially to the aroma , adding fruit and floral notes. The majority of Champagnes produced are non-vintage (or rather, multi-vintage) blends. Vintage Champagne, often a house's most prestigious and expensive wine, is also produced, but only in years when the producers feel that
33698-466: The rising price could produce a consumer backlash that would harm the industry for years into the future. That and political pressure from villages that wanted to be included in the expanded boundaries led to the move. Changes are subject to significant scientific review and are said not to impact Champagne-produced grapes until 2020. A final decision is not expected until 2023 or 2024. Sparkling wines are produced worldwide, but many legal structures reserve
33901-539: The sacrament of the Eucharist . French kings were traditionally anointed in Reims , and champagne was served as part of coronation festivities. The Champenois were envious of the reputation of the wines made by their Burgundian neighbours to the south and sought to produce wines of equal acclaim. However, the northern climate of the region gave the Champenois a unique set of challenges in making red wine . At
34104-424: The selection of the raw materials, e.g., sodium selenite may be preferred over easily evaporating selenium dioxide (SeO 2 ). Also, more readily reacting raw materials may be preferred over relatively inert ones, such as aluminium hydroxide (Al(OH) 3 ) over alumina (Al 2 O 3 ). Usually, the melts are carried out in platinum crucibles to reduce contamination from the crucible material. Glass homogeneity
34307-435: The situation of the name Sekt being possible to apply to sparkling wines of varying quality level. Sekt typically comes with a muselet (safety cage) to hold the cork in place despite its considerable CO 2 pressure. It also comes with a Schaumwein tax, which since 2005 has been €136 per hectolitre (€5.15/US gal; €6.18/imp gal), corresponding to €1.02 per 0.75-litre (25 US fl oz) bottle. This tax
34510-450: The sparkling creations "The Devil's Wine". The British were the first to see the tendency of wines from Champagne to sparkle as a desirable trait and tried to understand why it produced bubbles. Wine was often transported to England in wooden wine barrels where merchant houses would then bottle the wine for sale. During the 17th century, English glass production used coal-fueled ovens and produced stronger, more durable glass bottles than
34713-466: The sparkling wine. Wines produced within the European Union must include the sweetness level on the wine label . For wines produced outside the EU, the sweetness level is not required but if it is included on the label the terms used must conform to EU guidelines. The most well-known example of sparkling wine is that of Champagne from the Champagne wine region of France. On average, Champagne
34916-603: The start of the 20th century. By the 17th century, glass in the Venetian tradition was also being produced in England . In about 1675, George Ravenscroft invented lead crystal glass, with cut glass becoming fashionable in the 18th century. Ornamental glass objects became an important art medium during the Art Nouveau period in the late 19th century. Throughout the 20th century, new mass production techniques led to
35119-469: The strength of glass. Carefully drawn flawless glass fibres can be produced with a strength of up to 11.5 gigapascals (1,670,000 psi). The observation that old windows are sometimes found to be thicker at the bottom than at the top is often offered as supporting evidence for the view that glass flows over a timescale of centuries, the assumption being that the glass has exhibited the liquid property of flowing from one shape to another. This assumption
35322-566: The surface. When they reach the surface they are approximately 1 millimeter in size. It is speculated that the bubbles in sparkling wine may speed up alcohol intoxication by helping the alcohol to reach the bloodstream faster. A study conducted at the University of Surrey in the United Kingdom gave subjects equal amounts of flat and sparkling champagne which contained the same levels of alcohol . After 5 minutes following consumption,
35525-500: The sweetness of the bottled wine: The most common style today is Brut . However, throughout the 19th century and into the early 20th century Champagne was generally much sweeter than it is today. Moreover, except in Britain, Champagne was drunk as dessert wines (after the meal), rather than as table wines (with the meal). At this time, Champagne sweetness was instead referred to by destination country, roughly as: Of these, only
35728-460: The system Al-Fe-Si may undergo a first-order transition to an amorphous form (dubbed "q-glass") on rapid cooling from the melt. Transmission electron microscopy (TEM) images indicate that q-glass nucleates from the melt as discrete particles with uniform spherical growth in all directions. While x-ray diffraction reveals the isotropic nature of q-glass, a nucleation barrier exists implying an interfacial discontinuity (or internal surface) between
35931-401: The term "Champagne" to relate the specific wine produced in the Champagne wine region. This includes objection to the term "Champagne style" to refer to sparkling wines produced outside the Champagne region. Since 1985, use of the term methode champenoise has been banned in all wines produced or sold in the European Union. Blending is the hallmark of Champagne wine, with most Champagnes being
36134-477: The term on labels before 2006 may continue to use it , provided the term is accompanied by the wine's actual origin (e.g., "California"). The majority of US-produced sparkling wines do not use the term Champagne on their labels, and some states, such as Oregon, ban producers in their states from using the term. Several key U.S. wine regions, such as those in California ( Napa , Sonoma Valley , Paso Robles ), Oregon , and Walla Walla, Washington , came to consider
36337-408: The territory is divided into next sub-regions, known as wine-producing districts, and each of them has distinct characteristics. The main wine-producing districts of the Champagne wine region: Reims, Marne Valley, Côte des Blancs, Côtes des Bar, Côtes de Sezzane. As a general rule, grapes used must be the white Chardonnay, or the dark-skinned "red wine grapes" Pinot noir or Pinot meunier, which, due to
36540-494: The total vintage's harvest for the production of vintage Champagne. This allows at least 20% of the harvest from each vintage to be reserved for use in non-vintage Champagne. This ensures a consistent style that consumers can expect from non-vintage Champagne that does not alter too radically depending on the quality of the vintage. In less than ideal vintages, some producers will produce a wine from only that single vintage and still label it as non-vintage rather than as "vintage" since
36743-552: The traditional method, most Italian sparkling wines, in particular Asti and Prosecco, are made with the Charmat method . Asti is a slightly sweet wine made from the Moscato grape in the province of Asti . The wine is noted for its low alcohol levels around 8% and fresh, grapey flavors. Moscato d'Asti is a frizzante style slightly sparkling version of Asti; it is sweeter and contains even less alcohol, typically around 5.5%. The Franciacorta region, located northwest of Brescia ,
36946-406: The transition is a result of the bottom section's being composed of two stacked discs of pristine cork cemented to the upper portion, which is a conglomerate of ground cork and glue. The bottom section is in contact with the wine. Before insertion, a sparkling wine cork is almost 50% larger than the opening of the bottle. Originally, the cork starts as a cylinder and is compressed before insertion into
37149-468: The turn of the 20th century, the majority of champagne drinkers were middle class . In the 19th century, champagne producers made a concentrated effort to market their wine to women. This is done by having the sweeter champagne associates with female, whereas the dry champagne with male and foreign markets. This was in stark contrast to the traditionally "male aura" that the wines of France had—particularly Burgundy and Bordeaux . Laurent-Perrier again took
37352-403: The village and vineyards that the grapes are from. Premium Sekt b.A. produced in smaller lots is often referred to as Winzersekt (winegrower's Sekt), since it is typically produced by a producer which has vineyards of his own, rather than by the large Sekt-producing companies ( Sektkellereien ) which buy grapes or base wine on a large scale for their production. In Austria, the corresponding term
37555-559: The warm winds rising from the valleys below. The River Marne runs west–east through Champagne, south of the Montagne de Reims. The Vallée de la Marne contains south-facing chalky slopes. Chardonnay gives the wine its acidity and biscuit flavour. Most Chardonnay is grown in a north–south-running strip to the south of Épernay , called the Côte des Blancs , including the villages of Avize , Oger and Le Mesnil-sur-Oger . These are east-facing vineyards, with terroir similar to
37758-451: The widespread availability of glass in much larger amounts, making it practical as a building material and enabling new applications of glass. In the 1920s a mould -etch process was developed, in which art was etched directly into the mould so that each cast piece emerged from the mould with the image already on the surface of the glass. This reduced manufacturing costs and, combined with a wider use of coloured glass, led to cheap glassware in
37961-408: The wine bottle (on average around 5 atmospheres ) and wine producers take care to package the wine in strong glass bottles. When the wine is opened and poured into a glass, the gas is released and the wine becomes sparkling. There are several methods used to carry out this secondary fermentation. The most well known is the traditional or "champagne method" where the base cuvée is bottled with
38164-462: The wine is determined by the amount of sugar added during the tirage stage at the beginning of the secondary fermentation with more sugar producing an increased amount of carbon dioxide gas and thus pressure in the wine. While the majority of sparkling wines are white or rosé , Australia, Italy and Moldova each have a sizable production of red sparkling wines. Of these, Italy has the longest tradition in red sparkling wine-making, particularly along
38367-514: The wine will be of lesser quality and the producers have little desire to reserve the wine for future blending. A cuvée de prestige is a proprietary blended wine (usually a Champagne) that is considered to be the top of a producer's range. Famous examples include Louis Roederer 's Cristal , Laurent-Perrier 's Grand Siècle , Moët & Chandon 's Dom Pérignon , Duval-Leroy 's Cuvée Femme , Armand de Brignac Gold Brut , and Pol Roger 's Cuvée Sir Winston Churchill . Perhaps
38570-549: The wood-fired French glass. The English also rediscovered the use of cork stoppers, once used by the Romans but forgotten for centuries after the fall of the Western Roman Empire . During the cold winters of the Champagne region, temperatures would drop so low that the fermentation process was prematurely halted—leaving some residual sugar and dormant yeast . When the wine was shipped to and bottled in England,
38773-525: The word Champagne exclusively for sparkling wines from the Champagne region, made in accordance with Comité Interprofessionnel du vin de Champagne regulations. In the European Union and many other countries, the name Champagne is legally protected by the Madrid system under an 1891 treaty, which reserved it for the sparkling wine produced in the eponymous region and adhering to the standards defined for it as an appellation d'origine contrôlée ;
38976-503: The world. The contents were found to be drinkable, with notes of truffles and caramel in the taste. There are now only two other bottles from the 1825 vintage extant. In July 2010, 168 bottles were found on board a shipwreck near the Åland Islands in the Baltic Sea by Finnish diver Christian Ekström. Initial analyses indicated there were at least two types of bottle from two different houses: Veuve Clicquot in Reims and
39179-402: The year 1268. The study found that the room temperature viscosity of this glass was roughly 10 Pa · s which is about 10 times less viscous than a previous estimate made in 1998, which focused on soda-lime silicate glass. Even with this lower viscosity, the study authors calculated that the maximum flow rate of medieval glass is 1 nm per billion years, making it impossible to observe in
39382-432: Was characteristic of people's tastes at the time, and Jeandet explained that it was common for people in the 19th century, such as Russians, to add sugar to their wine at dinner. It also contained higher concentrations of minerals such as iron, copper, and table salt than modern-day Champagne does. Champagne corks are mostly built from three sections and are referred to as agglomerated corks. The mushroom shape that occurs in
39585-553: Was created for the British in 1876. The only wines that are legally allowed to be named “Champagne” must be bottled within 100 miles of the Champagne region in France. The name is legally protected by European law and an 1891 treaty that requires true champagne to be produced in the Champagne region and made from the Pinot Meunier, Pinot Noir, or Chardonnay grapes grown in this region. The Champagne winemaking community, under
39788-575: Was created in 1872 by Josep Raventós . The vineyards of Penedés were devastated by the phylloxera plague, and the predominantly red vines were being replaced by large numbers of vines producing white grapes. After seeing the success of the Champagne region, Raventós decided to create the dry sparkling wine that has become the reason for the region's continued success. In the past the wine was referred to as Spanish Champagne (no longer permitted under EU law), or colloquially as champaña in Spanish. Cava
39991-579: Was famously introduced by Emperor Wilhelm II in 1902 to fund the expansion of the Imperial Navy . Germans also call some similar foreign wines Sekt , like Krimsekt [ de ] (often red) from Crimea . Glass Glass is an amorphous ( non-crystalline ) solid. Because it is often transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware , and optics . Some common objects made of glass are named after
40194-542: Was in common use by the 1890s. Germany long attempted to have the name Sekt reserved for sparkling wine from countries with German as an official language, but these regulations were annulled by the European Court of Justice in 1975. Another legal decision in the 1970s abolished the large producers' monopoly on Sekt production, allowing winemaking cooperatives and individual winegrowers to produce and sell their own sparkling wines. Together, these two decision produced
40397-459: Was noted in the Middle Ages but this was considered a wine fault and was disdained in early Champagne winemaking although it was the pride of other historic sparkling wine production areas like Limoux . Dom Pérignon was originally charged by his superiors at the Abbey of Hautvillers to get rid of the bubbles since the pressure in the bottles caused many of them to burst in the cellar. Later, when deliberate sparkling wine production increased in
40600-453: Was originally used in the United Kingdom and United States during World War II to manufacture radomes . Uses of fibreglass include building and construction materials, boat hulls, car body parts, and aerospace composite materials. Glass-fibre wool is an excellent thermal and sound insulation material, commonly used in buildings (e.g. attic and cavity wall insulation ), and plumbing (e.g. pipe insulation ), and soundproofing . It
40803-521: Was postponed until 1962, and this variety is no longer allowed in Champagne. The dark-skinned Pinot noir and Pinot meunier give the wine its length and backbone. They are predominantly grown in two areas – the Montagne de Reims and the Vallée de la Marne . The Montagne de Reims run east–west to the south of Reims, in northern Champagne. They are notable for north-facing chalky slopes that derive heat from
41006-556: Was rarely transparent and often contained impurities and imperfections, and is technically faience rather than true glass, which did not appear until the 15th century BC. However, red-orange glass beads excavated from the Indus Valley Civilization dated before 1700 BC (possibly as early as 1900 BC) predate sustained glass production, which appeared around 1600 BC in Mesopotamia and 1500 BC in Egypt. During
41209-437: Was restarted by United Kingdom winemakers after a long hiatus. Effervescence has been observed in wine throughout history and has been noted by Ancient Greek and Roman writers, but the cause of this mysterious appearance of bubbles was not understood. Over time it has been attributed to phases of the moon as well as both good and evil spirits . The tendency of still wine from the Champagne region to lightly sparkle
