63-455: Beer is produced through steeping a sugar source (commonly Malted cereal grains) in water and then fermenting with yeast. Brewing has taken place since around the 6th millennium BC, and archeological evidence suggests that this technique was used in ancient Egypt . Descriptions of various beer recipes can be found in Sumerian writings, some of the oldest known writing of any sort. Brewing
126-523: A laxative effect. The Burton breweries were known for a recirculating fermentation system known as the Burton Union. Invented in the 1830s, the Union system is a row of wood casks connected to a common trough by way of a series of pipes. The practical purpose of the Union system is to allow excess barm ( yeast foam) to be expelled from the casks without leaving excessive amounts of head space within
189-874: A saison . Among the better French known " bières de garde " are Brasserie de Saint-Sylvestre , Trois Monts, Brasseurs Duyck, Jenlain and Brasserie La Choulette, ambrée. Blonde ales are very pale in colour. The term "blonde" for pale beers is common in Europe and South America – particularly in France, Italy, Belgium, the Netherlands, the UK, and Brazil – though the beers may not have much in common, other than colour. Blondes tend to be clear, crisp, and dry, with low-to-medium bitterness and aroma from hops, and some sweetness from malt. Fruitiness from esters may be perceived. A lighter body from higher carbonation may be noticed. In
252-666: A British or European pale ale. The style is close to the American India pale ale (IPA), and boundaries blur, though IPAs are stronger and more assertively hopped. The style is also close to amber ale , though these are darker and maltier due to the use of crystal malts. Australian pale ale is pale ale that is produced in Australia and developed in Australia around 1990s. Australian pale ales are generally around 6% abv with significant quantities of Australian hops, typically Galaxy . Bière de garde , or "keeping beer",
315-669: A beer. Beers are aged for a period of time in a wooden barrel . Typically, these barrels once housed wine, rum, whiskey, bourbon, tequila, and other wines and spirits. Beers are sometimes aged in barrels to achieve a variety of effects in the final product. Sour beers such as lambics are fully fermented in wood (usually oak) barrels similar to those used to ferment wine, usually including microflora other than Saccharomyces cerevisiae . Other beers are aged in barrels which were previously used for maturing spirits . Stouts (particularly Russian Imperial Stouts ) are sometimes aged in bourbon barrels.

Malting grain develops the enzymes (α-amylase, β-amylase) required for modifying the grains' starches into various types of sugar, including monosaccharide glucose , disaccharide maltose , trisaccharide maltotriose , and higher sugars called maltodextrines . It also develops other enzymes, such as proteases , that break down the proteins in

This conditioning begins in tanks at the brewery and continues after the beer is filled into casks , hence the phrase 'Cask Conditioned'. Historically, the Yorkshire Square vessel was constructed from Yorkshire Sandstone , but Welsh slate quickly proved to be the material of choice. A modern innovation is the so-called 'Round Square' pioneered by
630-555: A pale beer, such as a pale ale . It is not used for dark beers such as stout . A degree of sulphate ions in the water is also appropriate for emulation of the Czech Pilsener style, and sulphate ions are also distinctive of Dortmunder Export . Introducing magnesium sulphate into the brewing water, or "liquor", creates a rounder, fuller taste that enhances other flavours in the beer. However, excessive dosage must be avoided to prevent undesirable consequences, which could include
693-438: A process called mashing to extract the sugars. Brewers warm cracked malt in temperature-modulated water, activating the enzymes, which cleave more of the malt's remaining starch into various sugars, the largest percentage of which is maltose . Modern beer-mashing practices typically include high enough temperatures at mash-out to deactivate remaining enzymes, thus it is no longer diastatic . The liquid produced from this, wort ,

These beers were usually brewed by farmhouses in the winter and spring, to avoid unpredictable problems with the yeast during the summertime. The origin of the name lies in the tradition that it was matured or cellared for a period of time once bottled (most were sealed with a cork), to be consumed later in the year, akin to
1008-484: Is a typical Belgian blonde ale, and one of the most popular bottled beers in the country as well as being well known internationally. Late in the second half of the nineteenth century, the recipe for pale ale was put into use by the Burton upon Trent brewers, notably Bass ; ales from Burton were considered of a particularly high quality due to synergy between the malt and hops in use and local water chemistry, especially

In addition, barley malts are distinguished by the two major cultivar types of barley used for malting, two-row, and six-row. Malt extract, also known as extract of malt, is a sweet, treacle -like substance used as a dietary supplement . It was popular in the first half of the 20th century as a nutritional enhancer for
1134-410: Is achieved during the mashing process. Various cereals are malted, though barley is the most common. A high-protein form of malted barley is often a label-listed ingredient in blended flours typically used in the manufacture of yeast bread and other baked goods. The term "malt" refers to several products of the process: the grains to which this process has been applied, for example, malted barley;
1197-443: Is an emerging term used in Australia, France (as ambrée ), Belgium and the Netherlands and North America for pale ales brewed with a proportion of amber malt and sometimes crystal malt to produce an amber colour generally ranging from light copper to light brown. A small amount of crystal or other coloured malt is added to the basic pale ale base to produce a slightly darker colour, as in some Irish and British pale ales. In France
1260-480: Is any cereal grain that has been made to germinate by soaking in water and then stopped from germinating further by drying with hot air, a process known as " malting ". Malted grain is used to make beer , whisky , malted milk , malt vinegar , confections such as Maltesers and Whoppers , flavored drinks such as Horlicks , Ovaltine , and Milo , and some baked goods, such as malt loaf , bagels , and Rich Tea biscuits. Malted grain that has been ground into

Anchor Liberty Ale, a 6% abv ale originally brewed by the Anchor Brewing Company as a special in 1975 to commemorate Paul Revere 's "Midnight Ride" in 1775, was seen by Michael Jackson , a writer on beverages, as the first modern American ale. Fritz Maytag , the owner of Anchor, visited British breweries in London, Yorkshire and Burton upon Trent , picking up information about robust pale ales, which he applied when he made his American version, using just malt rather than

#17327766626351386-437: Is done in a brewery by a brewer, and the brewing industry is part of most western economies. In 19th century Britain, technological discoveries and improvements such as Burtonisation and the Burton Union system significantly changed beer brewing. The methods used to produce beer may be unique to a beer style , geographic region, or company. Barrel aging is a process used to add maturity and character and additional flavour to
1449-436: Is often looked on as a technical challenge for advanced homebrewers , and a commercial approximation of the design is available for experimenters. Until February 2024 Marston's Pedigree was produced using the Burton Union system, when, citing declining cask ale sales and profitability concerns, Carlsberg Marston's announced the closure of the last original Burton Union sets. In May 2024, Thornbridge Brewery announced that with
1512-428: Is the process of converting barley or other cereal grains into malt for use in brewing, distilling , or foods, and takes place in a maltings , sometimes called a malthouse, or a malting floor. The cereal is spread out on the malting floor in a layer of 8 to 12 centimetres (3 to 4 + 1 ⁄ 2 inches) depth. A "maltings" is typically a long, single-storey building with a floor that slopes slightly from one end of
1575-475: Is then concentrated by using heat or a vacuum procedure to evaporate water from the mixture. The concentrated wort is called malt extract. Two forms of malt extract are used by brewers: liquid malt extract (LME), containing about 20% water, and dry malt extract (DME), dehydrated to 2% water. LME is a thick syrup that typically gives off more pleasant flavors than its counterpart, while DME provides better consistency in color. When using large amounts of extract, LME

However, those in favor of DME, enjoy its longer shelf life. LME is also sold in jars as a consumer product. A new encapsulating technology permits the production of malt granules . This process dries and coats layers of wort such that flavoring substances within
1701-478: The Calcutta Gazette for "light and excellent" pale ale. By 1830, the expressions bitter and pale ale were synonymous. Breweries tended to designate beers as "pale ales", though customers would commonly refer to the same beers as "bitters". It is thought that customers used the term bitter to differentiate these pale ales from other less noticeably hopped beers such as porters and milds . By
1764-635: The Refresh UK 's brewery in Witney, a new brewery was built to include the original double dropping system. Brakspear state that some of the flavour common to its beer is due to a combination of its very old complex multi-strain yeast and the dropping method which encourages it to produce the butterscotch-flavoured compound diacetyl . A Yorkshire Square vessel is a two-storey fermentation system developed in Huddersfield by Timothy Bentley, proprietor of

There are many other smaller and craft examples, such as O'Hara's, Sullivan's, Murphy's, Porterhouse and Franciscan Well. Irish red ales are characterised by their malt profile and typically have a sweet, caramel or toffee-like taste, low bitterness and amber to red colour - hence

During the double dropping process the wort (newly brewed, fermenting beer) is first fermented for a period of time before being transferred, under gravity or by other means, into a lower vessel where it continues fermentation. The dropping process has two primary effects on
1953-414: The mash of converted grain to create a filter bed during lautering . As all grains sprout, natural enzymes within the grain break down the starch of which the grain is composed into simpler sugars, which taste sweet and are easier for yeast to use as food. Malt with active enzymes is called "diastatic malt". Malt with inactive enzymes is called "nondiastatic malt". The enzymes are deactivated by heating

Cooled wort , the liquid extracted from malted barley, is fermented in the lower chamber, while the yeasty head settles on the deck above. During the first stage of fermentation, the fermenting wort is periodically pumped from the bottom of the chamber over the yeasty head, to keep

Cooked from rye malt and flour, mämmi has a great resemblance (in the recipe, color, and taste) to samanū . Today, this product is available in shops from February until Easter. A (nonrepresentative) survey in 2013 showed that almost no one cooks mämmi at home in modern-day Finland . Malting
2205-772: The United Kingdom, golden or summer ales were developed in the late 20th century by breweries to compete with the pale lager market. A typical golden ale has an appearance and profile similar to that of a pale lager. Malt character is subdued and the hop profile ranges from spicy to citrus; common hops include Styrian Golding and Cascade. Alcohol is in the 4% to 5% abv range. The UK style is attributed to John Gilbert, owner of Hop Back Brewery , who developed "Summer Lightning" in 1989, which won several awards and inspired numerous imitators. Belgian blondes are often made with pilsner malt . Some beer writers regard blonde and golden ales as distinct styles, while others do not. Duvel
2268-402: The beer being fermented: the trub that has settled during the first period of fermentation will be left behind, leaving a cleaner beer and a cleaner yeast to crop from the beer for the next fermentation; the second effect is the aeration of the wort, which results in healthy clean yeast growth, and in certain circumstances butterscotch flavours from the production of diacetyl . Breweries using
2331-430: The building to the other. Floor maltings began to be phased out in the 1940s in favor of "pneumatic plants", where large industrial fans are used to blow air through the germinating grain beds and to pass hot air through the malt being kilned. Like floor maltings, these pneumatic plants use batch processes, but of considerably greater size, typically 100-ton batches compared with 20-ton batches floor maltings. As of 2014 ,
2394-455: The casks; the system was quickly refined to separate any expelled beer from the wasted yeast, allowing it to flow back into the casks to continue fermentation. The Burton Union is credited with maintaining the strains of yeast used in Burton brewing in a relatively stable state until the mid-20th century. While not widely used in commercial beer production any longer, the Burton Union principle
2457-431: The chemical composition of the local water. In the early 19th century, pale ale was being successfully brewed in London. In 1822, the method had been copied by the Burton upon Trent brewer Samuel Allsopp , who got a more hoppy tasting version of the beer because of the sulphate-rich local water. The clean, crisp, bitter flavour of beer brewed by Allsopp in Burton became very popular and by 1888 there were 31 breweries in

The Codex indicates that diastatic activity is to be preserved by the use of temperatures not exceeding 55 °C (131 °F). Malt extract is frequently used in the brewing of beer. Its production begins by germinating barley grain in a process known as malting, immersing barley in water to encourage
2709-831: The expression "India pale ale" is in an advertisement in the Sydney Gazette and New South Wales Advertiser on 27 August 1829. Worthington White Shield , originating in Burton-upon-Trent, is a beer considered to be part of the development of India pale ale. The colour of an IPA can vary from a light gold to a reddish amber. The term "Irish red ale" was popularised in the United States and subsequently exported worldwide. The additional variants "red ale", "Irish ale" ( Irish : leann dearg , ) and "Irish red", have come to be used by brewers mainly in Ireland and
2772-591: The finished version in March 1981. Other pioneers of a hoppy American pale ale are Jack McAuliffe of the New Albion Brewing Company and Bert Grant of Yakima Brewing . American pale ales are generally around 5% abv, with significant quantities of American hops, typically Cascade. Although American-brewed beers tend to use a cleaner yeast, and American two row malt, it the use of strong American hops in particular that distinguish an APA from
2835-403: The grain into forms that can be used by yeast . The point at which the malting process is stopped affects the starch -to-enzyme ratio, and partly converted starch becomes fermentable sugars. Malt also contains small amounts of other sugars, such as sucrose and fructose , which are not products of starch modification, but which are already in the grain. Further conversion to fermentable sugars
2898-424: The grain to sprout, then drying it to halt the progress when the sprouting begins. The drying step stops the sprouting, but the enzymes remain active due to the low temperatures used in base malt production. In one before-and-after comparison, malting decreased barley's extractable starch content by about 7% on a dry matter basis and turned that portion into various other carbohydrates. In the next step, brewers use
2961-444: The industry doesn't recognise as barrel aging. A backlash from other brewers using the term in its traditionally understood sense ensued and the outcome is, to date, unresolved. Burtonisation is the act of adding sulphate , often in the form of gypsum , to the water used for the brewing of beer, to bring out the flavour of the hops . The name comes from the town of Burton upon Trent which had several very successful breweries due to
3024-529: The largest malting operation in the world was Malteurop, which operates in 14 countries. Barley is the most commonly malted grain, in part because of its high content of enzymes , though wheat, rye , oats , rice, and corn are also used. Also very important is the retention of the grain's husk , even after threshing , unlike the bare seeds of threshed wheat or rye. This protects the growing acrospire (developing plant embryo ) from damage during malting, which can easily lead to mold growth; it also allows
3087-660: The malt and sugar combination common in brewing at that time, and making prominent use of the American hop, Cascade . By 1983, it was commonly found. The brewery thought to be the first to successfully use significant quantities of American hops in the notably hoppy style of an APA and use the specific name "pale ale" was the Sierra Nevada Brewing Company . It brewed the first experimental batch of Sierra Nevada Pale Ale in November 1980, distributing
3150-527: The malt. Malt is often divided into two categories by brewers: base malts and specialty malts. Base malts have enough diastatic power to convert their own starch and usually, that of some amount of starch from unmalted grain, called adjuncts . Specialty malts have little diastatic power, but provide flavor, color, or "body" ( viscosity ) to the finished beer. Specialty caramel or crystal malts have been subjected to heat treatment to convert their starches to sugars nonenzymatically. Within these categories
3213-439: The mid to late 20th century, while brewers were still labelling bottled beers as pale ales, they had begun identifying cask beers as "bitters", except those from Burton on Trent , which tend to be referred to as "pale ales". Different brewing practices and hop levels have resulted in a range of taste and strength within the pale ale family. Collier Brothers of London applied for the UK trademark of The Amber Ale in 1876 and

#17327766626353276-647: The name. Irish brewers have increasingly adopted the term Irish Red Ale to distinguish their beers in both the domestic and international markets. In the US, the name can also be used simply to describe a darker amber ale, or the abbreviated term "Irish Red" applied to a "reddish" beer brewed as a lager and ambered with caramel colouring - for example Killian's Irish Red . Strong pale ales are ales made predominantly with pale malts and have an alcohol strength that may start around 5%, though typically at 7 or 8% by volume, and may go up to 12%, though some brewers have been pushing
3339-682: The original wort are not volatilized during storage or transport, further extending shelf life, and reducing dust during handling. This new process may allow for more centralized and standardized production of the extract than what would have been traditionally prepared at individual breweries. Scientists aim to discover what happens inside barley grains as they become malted to help plant breeders produce better malting barley for food and beverage products. The United States Agricultural Research Service scientists are interested in specialized enzymes called serine-class proteases that digest beta-amylases, which convert carbohydrates into "simple sugars" during
3402-507: The presence of gypsum . Burton retained absolute dominance in pale ale brewing until a chemist, C. W. Vincent, discovered the process of Burtonization to reproduce the chemical composition of the water from Burton-upon-Trent, thus giving any brewery the capability to brew pale ale. The expression English bitter first appeared in the early 19th century as part of the development and spread of pale ale. Breweries tended to designate beers as "pale ales", though customers would commonly refer to
3465-465: The same beers as "bitters". It is thought that customers used the term bitter to differentiate these pale ales from other less noticeably hopped beers. Drinkers tend to loosely group modern bitters into "session" or "ordinary" bitters (up to 4.1% abv), "best" or "special" bitters (between 4.2% and 4.7% abv) and "strong" bitters (4.8% abv and over). India pale ale (IPA) is a style of pale ale developed in England for export to India. The first known use of
3528-492: The sprouting process. The enzyme also breaks down stored proteins into their amino-acid derivatives. The balance of proteins and carbohydrates broken down by the enzyme affects the malt's flavor. Enzyme-rich malt extract (ERME) is a specialised form of barley malt extract (marketed by Ateria Health ), that has undergone preparation to activate the natural amylase and glucanase enzymes in the grain. Initially researched as an equine food supplement, pilot studies using ERME as
