114-526: Cains was a brewery in Liverpool , England , founded in 1858 by Robert Cain . The company merged with Peter Walker & Son in 1921 to form Walker Cains . Peter Walker & Son had a large brewery in Warrington so sold its Liverpool brewery to Higsons in 1923. Boddingtons of Manchester took over in 1985. In 1990, Whitbread acquired Boddington's brewing operations and closed the brewery. It

228-421: A beer tap at its base. Beer contains the phenolic acids 4-hydroxyphenylacetic acid , vanillic acid , caffeic acid , syringic acid , p -coumaric acid , ferulic acid , and sinapic acid . Alkaline hydrolysis experiments show that most of the phenolic acids are present as bound forms and only a small portion can be detected as free compounds. Hops , and beer made with it, contain 8-prenylnaringenin which

342-628: A beer with the consistency of gruel, used by the semi-nomadic Natufians for ritual feasting, at the Raqefet Cave in the Carmel Mountains near Haifa in northern Israel . There is evidence that beer was produced at Göbekli Tepe during the Pre-Pottery Neolithic (around 8500  BC to 5500  BC ). The earliest clear chemical evidence of beer produced from barley dates to about 3500–3100  BC , from

456-692: A better understanding of the brewing process. Today, almost all brewery equipment is made of stainless steel . During the Industrial Revolution, the production of beer moved from artisanal manufacture to industrial manufacture , and domestic manufacture ceased to be significant by the end of the 19th century. In addition to changes in manufacturing capacity, the number of breweries grew throughout industrialization. For example in America, number of breweries rose from 431 to 4,131 between 1850 and 1873. A handful of major breakthroughs have led to

570-523: A conclusion that would have avoided administration. The brewery and eight original pubs were bought back by the Dusanj brothers for £103,750. As the Dusanji family holds the freehold to the brewery site and controls the terms of any lease for brewery operation, no other buyer could be found. In 2013, it ended contract brewing and production of supermarket beers, and then ceased brewing altogether, finding

684-440: A conical bottom and a cylindrical top. The cone's aperture is typically around 70°, an angle that will allow the yeast to flow smoothly out through the cone's apex at the end of fermentation, but is not so steep as to take up too much vertical space. CCVs can handle both fermenting and conditioning in the same tank. At the end of fermentation, the yeast and other solids have fallen to the cone's apex can be simply flushed out through

798-829: A contract brewer for its own beers. 38 staff were made redundant . Cains was down to an estate of three pubs – the Brewery Tap, Dr Duncan's and The Dispensary. By 2015, it had an estate of five pubs, the additional two being Kelly's Dispensary in Smithdown Road and The Edinburgh in Wavertree. In 2013, Cains began a redevelopment of the site for leisure and housing with a small craft brewery to continue production of its ales. In 2014, Cains arranged for small quantities of its beers to be contract-brewed for export and sale in it pub estate. Liverpool City Council granted planning permission for Cains Brewery Village in 2013. This

912-416: A daily ration of four to five litres of beer, which served as both nutrition and refreshment and was crucial to the pyramids' construction. Some of the earliest Sumerian writings contain references to beer; examples include a prayer to the goddess Ninkasi , known as "The Hymn to Ninkasi", which served as both a prayer and a method of remembering the recipe for beer in a culture with few literate people, and

1026-539: A degree that brewers of pale ale add gypsum in a process known as Burtonisation . The starch source provides the fermentable material and determines the strength and flavour of the beer. The most common starch source used in beer is malted grain. Grain is malted by soaking it in water, allowing it to begin germination , and then drying the partially germinated grain in a kiln. Malting produces enzymes that convert starches into fermentable sugars. Different roasting times and temperatures produce different colours of malt from

1140-431: A dense head and a creamy mouthfeel . In the 1980s, Guinness introduced the beer widget , a nitrogen-pressurised ball inside a can which creates a moderately dense, tight head. This approximates the effect of serving from a keg, at least for a British-style beer which does not have a specially large head. Cask-conditioned ales (or cask ales) are unfiltered and unpasteurised beers. These beers are termed " real ale " by

1254-481: A document from that year refers to a hop garden in the area paying a tithe to the monastery. It claims to be the oldest working brewery in the world. Top-fermented beers are most commonly produced with Saccharomyces cerevisiae , a top-fermenting yeast which clumps and rises to the surface, typically between 15 and 25 °C (59 and 77 °F). At these temperatures, yeast produces significant amounts of esters and other secondary flavour and aroma products, and

1368-562: A formal education in the subject from institutions such as the Siebel Institute of Technology , VLB Berlin , Heriot-Watt University , American Brewers Guild, University of California at Davis , University of Wisconsin , Olds College or Niagara College . They may hold membership in professional organisations such as the Brewers Association , Master Brewers Association , American Society of Brewing Chemists ,

1482-437: A garden for outside dining. Brewery A brewery or brewing company is a business that makes and sells beer . The place at which beer is commercially made is either called a brewery or a beerhouse , where distinct sets of brewing equipment are called plant. The commercial brewing of beer has taken place since at least 2500 BC; in ancient Mesopotamia , brewers derived social sanction and divine protection from

1596-534: A medical context, alcoholism is said to exist when two or more of the following conditions are present: a person drinks large amounts over a long time period, has difficulty cutting down, acquiring and drinking alcohol takes up a great deal of time, alcohol is strongly desired, usage results in not fulfilling responsibilities, usage results in social problems, usage results in health problems, usage results in risky situations, withdrawal occurs when stopping, and alcohol tolerance has occurred with use. Alcoholism reduces

1710-509: A more carbonated beer. When the sugars in the fermenting beer have been almost completely digested, the fermentation process slows and the yeast cells begin to die and settle at the bottom of the tank. At this stage, especially if the beer is cooled to around freezing, most of the remaining live yeast cells will quickly become dormant and settle, along with the heavier protein chains, due simply to gravity and molecular dehydration. Conditioning can occur in fermentation tanks with cooling jackets. If

1824-555: A natural preservative and stabilising agent . Other flavouring agents, such as gruit , herbs, or fruits, may be included or used instead of hops. In commercial brewing, natural carbonation is often replaced with forced carbonation. Beer is distributed in bottles and cans, and is commonly available on draught in pubs and bars. The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries . The strength of modern beer

1938-408: A non-profit UK beer organisation, has set a temperature standard range of 12°–14 °C (53°–57 °F) for cask ales to be served. Beer is consumed out of a variety of vessels, such as a glass, a beer stein , a mug, a pewter tankard , a beer bottle or a can; or at music festivals and some bars and nightclubs, from a plastic cup. The shape of the glass from which beer is consumed can influence

2052-714: A notable exception). Heating in the brewhouse usually is achieved through pressurized steam, although direct-fire systems are not unusual in small breweries. Likewise, cooling in other areas of the brewery is typically done by cooling jackets on tanks, which allow the brewer to control precisely the temperature on each tank individually, although whole-room cooling is also common. Today, modern brewing plants perform myriad analyses on their beers for quality control purposes. Shipments of ingredients are analyzed to correct for variations. Samples are pulled at almost every step and tested for [oxygen] content, unwanted microbial infections, and other beer-aging compounds. A representative sample of

2166-623: A popular semi-fermented rice/millet drink in the eastern Himalayas . The Andes in South America has Chicha , made from germinated maize (corn); while the indigenous peoples in Brazil have Cauim , a traditional drink made since pre-Columbian times by chewing manioc so that an enzyme ( amylase ) present in human saliva can break down the starch into fermentable sugars; this is similar to Masato in Peru . Beers made from bread , among

2280-639: A port at the apex. Open fermentation vessels are also used, often for show in brewpubs, and in Europe in wheat beer fermentation. These vessels have no tops, making it easy to harvest top-fermenting yeasts. The open tops of the vessels increase the risk of contamination, but proper cleaning procedures help to control the risk. Fermentation tanks are typically made of stainless steel . Simple cylindrical tanks with beveled ends are arranged vertically, and conditioning tanks are usually laid out horizontally. A very few breweries still use wooden vats for fermentation but wood

2394-442: A seal less prone to leaking over time than bottles. Cans were initially viewed as a technological breakthrough for maintaining the quality of a beer, then became commonly associated with less expensive, mass-produced beers, even though the quality of storage in cans is much like bottles. Plastic ( PET ) bottles are used by some breweries. The temperature of a beer has an influence on a drinker's experience; warmer temperatures reveal

2508-539: A secondary carbohydrate source, such as maize (corn), rice, wheat, or sugar, often termed an adjunct , especially when used alongside malted barley. Less widely used starch sources include millet , sorghum , and cassava root in Africa; potato in Brazil; and agave in Mexico. Water is the main ingredient, accounting for 93% of beer's weight. The level of dissolved bicarbonate influences beer's finished taste. Due to

2622-472: A single group of nondrinkers, which hides the health benefits of lifelong abstention from ethanol. The long-term health effects of continuous, moderate or heavy alcohol consumption include the risk of developing alcoholism and alcoholic liver disease . Alcoholism , also known as "alcohol use disorder", is a broad term for any drinking of alcohol that results in problems. It was previously divided into two types: alcohol abuse and alcohol dependence . In

2736-404: A source of bitterness, flavour, and aroma. The longer the hops are boiled, the more bitterness they contribute, but the less hop flavour and aroma remain. The wort is cooled and the yeast is added. The wort is then fermented, often for a week or longer. The yeast settles, leaving the beer clear. During fermentation, most of the carbon dioxide is allowed to escape through a trap . The carbonation

2850-411: A store or a bar, rather than buying pre-bottled beer, can reduce the environmental impact of beer consumption. Most beers are cleared of yeast by filtering when packaged in bottles and cans. However, bottle conditioned beers retain some yeast—either by being unfiltered, or by being filtered and then reseeded with fresh yeast. Many beers are sold in cans, though there is considerable variation in

2964-538: A strong, sweet drink rather like mead or cider . Whatever the case, the meaning of bēor expanded to cover the meaning of ale . When hopped ale from Europe was imported into Britain in the late Middle Ages, it was described as 'beer' to differentiate it from the British unhopped ale, later acquiring a broader meaning. Beer is one of the world's oldest prepared alcoholic drinks. The earliest archaeological evidence of fermentation consists of 13,000 year-old residues of

3078-517: A year. A brewpub is a type of microbrewery that incorporates a pub or other drinking establishment . The highest density of breweries in the world, most of them microbreweries, exists in Franconia , Germany, especially in the district of Upper Franconia , which has about 200 breweries. The Benedictine Weihenstephan brewery in Bavaria , Germany, can trace its roots to the year 768, as

3192-423: Is a potent phytoestrogen . Hop also contains myrcene , humulene , xanthohumol , isoxanthohumol , myrcenol , linalool , tannins, and resin . The alcohol 2M2B is a component of hops brewing. Barley, in the form of malt, brings the condensed tannins prodelphinidins B3 , B9 and C2 into beer. Tryptophol , tyrosol , and phenylethanol are aromatic higher alcohols ( congeners ) produced by yeast during

3306-496: Is a preservative. Yeast is the microorganism responsible for fermenting beer. It metabolises the sugars, producing ethanol and carbon dioxide , and thereby turns wort into beer. In addition, yeast influences the character and flavour. The dominant types of beer yeast are top-fermenting Saccharomyces cerevisiae and bottom-fermenting Saccharomyces pastorianus . Brettanomyces ferments lambics , and Torulaspora delbrueckii ferments Bavarian weissbier . Before

3420-425: Is an optional process. Many craft brewers simply remove the coagulated and settled solids and forgo active filtration. In localities where a tax assessment is collected by government pursuant to local laws, any additional filtration may be done using an active filtering system, the filtered product finally passing into a calibrated vessel for measurement just after any cold conditioning and prior to final packaging where

3534-403: Is brewed with a large proportion of wheat although it often also contains a significant proportion of malted barley . Wheat beers are usually top-fermented . Stout is a dark beer made using roasted barley, and typically brewed with slow fermenting yeast. There are a number of variations including dry stout (such as Guinness ), sweet stout, and Imperial (or Russian) stout. Stout was originally

3648-453: Is brewing. It converts the grain into a sugary liquid called wort and then ferments this into beer in a using yeast . The first step, mixing malted barley with hot water in a mash tun , is " mashing ". The starches are converted to sugars, and the sweet wort is drained off. The grains are washed to extract as much fermentable liquid from the grains as possible. The sweet wort is put into a kettle, or "copper", and boiled. Hops are added as

3762-417: Is determined by the malt. The most common colour is a pale amber produced from using pale malts. Pale lager and pale ale are terms used for beers made from malt dried and roasted with the fuel coke . Coke was first used for roasting malt in 1642, but it was not until around 1703 that the term pale ale was used. In terms of sales volume, most of today's beer is based on the pale lager brewed in 1842 in

3876-505: Is difficult to keep clean and infection-free and must be repitched often, perhaps yearly. After high kräusen, the point at which fermentation is most active and copious foam is produced, a valve known in German as the spundapparat may be put on the tanks to allow the carbon dioxide produced by the yeast to naturally carbonate the beer. This bung device can regulate the pressure to produce different types of beer; greater pressure produces

3990-413: Is mashed to convert starch in the grain to sugars , which dissolve in water to form wort . Fermentation of the wort by yeast produces ethanol and carbonation in the beer. Beer is one of the oldest alcoholic drinks in the world, the most widely consumed, and the third most popular drink after water and tea . Most modern beer is brewed with hops , which add bitterness and other flavours and act as

4104-516: Is not a meal in itself. A 2016 systematic review and meta-analysis found that moderate ethanol consumption brought no mortality benefit compared with lifetime abstention from ethanol consumption. Some studies have concluded that drinking small quantities of alcohol (less than one drink in women and two in men, per day) is associated with a decreased risk of heart disease , stroke , diabetes mellitus , and early death. Some of these studies combined former ethanol drinkers and lifelong abstainers into

4218-454: Is often increased either by transferring the beer to a pressure vessel and introducing pressurised carbon dioxide or by transferring it before the fermentation is finished so that carbon dioxide pressure builds up inside the container. The basic ingredients of beer are water; a starch source, usually malted barley ; a brewer's yeast to produce the fermentation; and a flavouring such as hops . A mixture of starch sources may be used, with

4332-461: Is partially frozen and the ice is repeatedly removed, until the desired strength is reached, a process that may class the product as spirits rather than beer. The German brewery Schorschbräu's Schorschbock , a 31% ABV eisbock, and Hair of the Dog 's Dave , a 29% abv barley wine made in 1994, used the same fractional freezing method. A 60% ABV blend of beer with whiskey was jokingly claimed as

4446-424: Is the sole commercial use of hops . The flower of the hop vine acts as a flavouring and preservative agent in nearly all beer made today. The flowers themselves are often called "hops". The first historical mention of the use of hops in beer dates from 822 AD in monastery rules written by Adalard of Corbie , though widespread cultivation of hops for use in beer began in the thirteenth century. Before then, beer

4560-493: Is typically divided into distinct sections, with each section reserved for one part of the brewing process. Beer may have been known in Neolithic Europe and was mainly brewed on a domestic scale. In some form, it can be traced back almost 5000 years to Mesopotamian writings describing daily rations of beer and bread to workers. Before the rise of production breweries, the production of beer took place at home and

4674-625: Is usually around 4% to 6% alcohol by volume (ABV). Some of the earliest writings mention the production and distribution of beer: the Code of Hammurabi included laws regulating it, while "The Hymn to Ninkasi ", a prayer to the Mesopotamian goddess of beer, contains a recipe for it. Beer forms part of the culture of many nations and is associated with social traditions such as beer festivals , as well as activities like pub crawling , pub quizzes , and pub games . In early forms of English and in

4788-752: Is usually around 4% to 6%, measured as alcohol by volume (ABV). The perceived bitterness is measured by the International Bitterness Units scale (IBU), defined in co-operation between the American Society of Brewing Chemists and the European Brewery Convention . The international scale was a development of the European Bitterness Units scale, often abbreviated as EBU, and the bitterness values should be identical. Beer colour

4902-470: The CAMRA organisation. When a cask arrives in a pub, it is placed horizontally on a " stillage " frame, designed to hold it steady and at the right angle, and then allowed to cool to cellar temperature (typically between 11–13 °C or 52–55 °F), before being tapped and vented—a tap is driven through a rubber bung at the bottom of one end, and a hard spile is used to open a hole in the uppermost side of

5016-473: The Industrial Revolution was made and sold on a domestic scale, although by the 7th century AD, beer was also being produced and sold by European monasteries . During the Industrial Revolution, the production of beer moved from artisanal to industrial manufacture , while domestic production ceased to be significant by the end of the 19th century. In 1912, brown bottles began to be used by

5130-579: The Institute of Brewing and Distilling , and the Society of Independent Brewers . Depending on a brewery's size, a brewer may need anywhere from five to fifteen years of professional experience before becoming a brewmaster. Beer Beer is an alcoholic beverage produced by the brewing and fermentation of starches from cereal grain—most commonly malted barley , although wheat , maize (corn), rice , and oats are also used. The grain

5244-814: The Joseph Schlitz Brewing Company of Milwaukee, Wisconsin , in the United States. This innovation has since been accepted worldwide as it prevents light rays from degrading the quality and stability of beer. The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers, ranging from brewpubs to regional breweries . As of 2006, more than 133 billion litres (35 billion US gallons) of beer are sold per year, producing global revenues of US$ 294.5 billion. In 2010, China's beer consumption hit 450 billion litres (120 billion US gallons), or nearly twice that of

5358-684: The Philharmonic Dining Rooms , the Vines and the Central Commercial Hotel, which are currently listed as being of architectural merit. His personal mansion had each window arch inscribed with his monogram. In 1887 construction began on a second brewery. In 1921, 14 years after Cain's death, the Cains brewery merged with Walkers of Warrington , becoming Walker Cains. Then in 1923 the original Stanhope Street Brewery

5472-763: The UEFA Champions League with its namesake lager; Carlsberg sponsors the English Premier League as well as the 2012 and 2016 UEFA European Championships . Meanwhile, the AB InBev Group supports the FA Cup and the FIFA World Cup . The head brewer (UK) or brewmaster (US) is in charge of the production of beer. The major breweries employ engineers with a chemistry / biotechnology background. Brewmasters may have had

5586-611: The brewer expects to evaporate . Fermentation begins as soon as yeast is added to the cooled wort. This is also the point at which the product is first called beer. It is during this stage that fermentable sugars won from the malt (maltose, maltotriose, glucose, fructose and sucrose) are metabolized into alcohol and carbon dioxide . Fermentation tanks come in many shapes and sizes, from enormous cylindroconical vessels that can look like storage silos , to 20- litre (5  US gal ) glass carboys used by homebrewers. Most breweries today use cylindroconical vessels (CCVs), which have

5700-552: The mineral properties of each region 's water, specific areas were originally the sole producers of certain types of beer, each identifiable by regional characteristics. Dublin 's hard water is well-suited to making stout , such as Guinness , while the Plzeň Region 's soft water is ideal for brewing Pilsner , such as Pilsner Urquell . The waters of Burton in England contain gypsum , which benefits making pale ale to such

5814-438: The starches in the grain into sugars , especially maltose . Lautering is the separation of the extracts won during mashing from the spent grain to create wort . It is achieved in either a lauter tun , a wide vessel with a false bottom, or a mash filter, a plate-and-frame filter designed for this kind of separation. Lautering has two stages: first wort run-off, during which the extract is separated in an undiluted state from

In 2002, South African Breweries bought the North American Miller Brewing Company to found SABMiller , becoming the second-largest brewery after North American Anheuser-Busch . In 2004, the Belgian Interbrew was the third-largest brewery by volume, and the Brazilian AmBev was the fifth-largest. They merged into InBev , becoming

6042-530: The CO 2 emissions from a 6-pack of micro-brew beer is about 3 kilograms (6.6 pounds). The loss of natural habitat potential from the 6-pack of micro-brew beer is estimated to be 2.5 square metres (26 square feet). Downstream emissions from distribution, retail, storage and disposal of waste can be over 45% of a bottled micro-brew beer's CO 2 emissions. Where legal, the use of a refillable jug, reusable bottle or other reusable containers to transport draught beer from

6156-525: The Scandinavian languages, the usual word for beer was the word whose Modern English form is ale . The modern word beer comes into present-day English from Old English bēor , itself from Common Germanic , it is found throughout the West Germanic and North Germanic dialects (modern Dutch and German bier , Old Norse bjórr ). The earlier etymology of the word is debated:

6270-471: The UK market and put Cains up for sale in 2002. Cains was acquired in 2002 by the Dusanj brothers making them the first Asian owners of a British brewery. At the time it had a turnover of £30 million, but took just over ten years to go into administration with debts, indicating a loss of £38 million - sinking over £3.5 million per year. In 2007, a reverse takeover of AIM-listed pub operator Honeycombe Leisure plc

6384-462: The United States, but only 5 per cent sold were premium beers, compared with 50 per cent in France and Germany. Beer is the most widely consumed of all alcoholic drinks. A widely publicised study in 2018 suggested that sudden decreases in barley production due to extreme drought and heat could in the future cause substantial volatility in the availability and price of beer. The process of making beer

6498-622: The adverts printed on football team's kit. For example, Liverpool F.C. had the logo of the Denmark-based Carlsberg brewery group on the front of its shirts for nearly twenty years, from 1992 to 2010. Nowadays major brewing corporations are involved in sponsorship on a number of different levels. The prevailing trend is for the leading brand not to be linked to individual teams; rather, they achieve visibility as sponsor of tournaments and leagues, so all fans can engage with them regardless of which team they support. Heineken sponsors

6612-541: The alcohol content of their beers. Samuel Adams reached 20% ABVwith Millennium , and then surpassed that amount to 25.6% ABV with Utopias . The strongest beer brewed in Britain was Baz's Super Brew by Parish Brewery, a 23% ABVbeer. In September 2011, the Scottish brewery BrewDog produced Ghost Deer, which, at 28%, they claim to be the world's strongest beer produced by fermentation alone. The product claimed to be

6726-566: The ancient advice ("Fill your belly. Day and night make merry") to Gilgamesh , recorded in the Epic of Gilgamesh by the alewife Siduri , may, at least in part, have referred to the consumption of beer. The Ebla tablets , discovered in 1974 in Ebla , Syria , show that beer was produced in the city in 2500 BC. A fermented drink using rice and fruit was made in China around 7000 BC. Unlike sake , mould

6840-422: The beer appear bright and clean, rather than the cloudy appearance of ethnic and older styles such as wheat beers . Clarifying agents include isinglass , from the swimbladders of fish; Irish moss , a seaweed; kappa carrageenan , from the seaweed Kappaphycus cottonii ; Polyclar (artificial); and gelatin . Beer marked "suitable for vegans" is clarified either with seaweed or with artificial agents. In

6954-627: The beer is put into the containers for shipment or sale. The container may be a bottle , can , of keg , cask or bulk tank. Filters come in many types. Many use pre-made filtration media such as sheets or candles. Kieselguhr, a fine powder of diatomaceous earth , can be introduced into the beer and circulated through screens to form a filtration bed. Filtration ratings are divided into rough, fine, and sterile. Rough filters remove yeasts and other solids, leaving some cloudiness, while finer filters can remove body and color. Sterile filters remove almost all microorganisms. Brewing companies range widely in

7068-491: The beer's marketing, sales, and distribution, while leaving the brewing and packaging to the producer-brewery (which confusingly may also be referred to as a contract brewer). Often the contract brewing is performed when a small brewery can not supply enough beer to meet demands and contracts with a larger brewery to help alleviate their supply issues. Some breweries do not own a brewing facility, these contract brewers have been criticized by traditional brewing companies for avoiding

7182-815: The beer. Most brewers would produce enough beer during winter to last through the summer, and store it in underground cellars, or even caves, to protect it from summer's heat. The discovery of microbes by Louis Pasteur was instrumental in the control of fermentation. The idea that yeast was a microorganism that worked on wort to produce beer led to the isolation of a single yeast cell by Emil Christian Hansen . Pure yeast cultures allow brewers to pick out yeasts for their fermentation characteristics, including flavor profiles and fermentation ability. Some breweries in Belgium, however, still rely on "spontaneous" fermentation for their beers (see lambic ). The development of hydrometers and thermometers changed brewing by allowing

7296-400: The beers to continue to ferment, and to clear any sediment. Lager yeast is a cool bottom-fermenting yeast ( Saccharomyces pastorianus ). Lager typically undergoes primary fermentation at 7–12 °C (45–54 °F), and then a long secondary fermentation at 0–4 °C (32–39 °F) (the lagering phase). During the secondary stage, the lager clears and mellows. The cooler conditions inhibit

7410-499: The brewer more control of the process, and greater knowledge of the results. Breweries today are made predominantly of stainless steel , although vessels often have a decorative copper cladding for a nostalgic look. Stainless steel has many favourable characteristics that make it a well-suited material for brewing equipment. It imparts no flavour in beer, it reacts with very few chemicals, which means almost any cleaning solution can be used on it (concentrated chlorine [bleach] being

7524-445: The brewer to make greater quantities of beer, as human power was no longer a limiting factor in moving and stirring. Carl von Linde , along with others, is credited with developing the refrigeration machine in 1871. Refrigeration allowed beer to be produced year-round, and always at the same temperature. Yeast is very sensitive to temperature, and, if a beer were produced during summer, the yeast would impart unpleasant flavours onto

7638-412: The brewing process. as secondary products of alcoholic fermentation Beers vary in their nutritional content. The ingredients used to make beer, including the yeast , provide a rich source of nutrients; therefore beer may contain nutrients including magnesium , selenium , potassium , phosphorus , biotin , chromium and B vitamins . Beer is sometimes referred to as "liquid bread ", though beer

7752-623: The cask. The act of stillaging and then venting a beer in this manner typically disturbs all the sediment, so it must be left for a suitable period of hours to days to "drop" (clear) again, as well as to fully condition the beer . At this point the beer is ready to sell, either being pulled through a beer line with a hand pump, or simply being "gravity-fed" directly into the glass. Draught beer's environmental impact can be 68% lower than bottled beer due to packaging differences. A life cycle study of one beer brand, including grain production, brewing, bottling, distribution and waste management, shows that

7866-696: The city of Plzeň in the present-day Czech Republic . The modern pale lager is light in colour due to use of coke for kilning, which gives off heat with little smoke. Dark beers are usually brewed from a pale malt or lager malt base with a small proportion of darker malt added to achieve the desired shade. Other colourants—such as caramel—are also widely used to darken beers. Very dark beers, such as stout , use dark or patent malts that have been roasted longer. Some have roasted unmalted barley. Beer ranges from less than 3% alcohol by volume (abv) to around 14% abv, though this strength can be increased to around 20% by re-pitching with champagne yeast, and to 55% ABVby

7980-449: The container from which it is dispensed, and served without the use of extraneous carbon dioxide ". It is applied to both bottle conditioned and cask conditioned beers. As for the types of top-fermented beers, pale ale predominantly uses pale malt. It is one of the world's major beer styles and includes India pale ale (IPA). Mild ale has a predominantly malty palate. It is usually dark, with an abv of 3% to 3.6%. Wheat beer

8094-825: The costs associated with a physical brewery. Gypsy, or nomad, brewing usually falls under the category of contract brewing. Gypsy breweries generally do not have their own equipment or premises. They operate on a temporary or itinerant basis out of the facilities of another brewery, generally making "one-off" special occasion beers. The trend of gypsy brewing spread early in Scandinavia . Their beers and collaborations later spread to America and Australia. Gypsy brewers typically use facilities of larger makers with excess capacity . Prominent examples include Pretty Things, Stillwater Artisanal Ales, Gunbarrel Brewing Company, Mikkeller , and Evil Twin . For example, one of Mikkeller's founders, Mikkel Borg Bjergsø, has traveled around

8208-426: The development of artificial refrigeration and by the 1870s, was spread in those countries that concentrated on brewing pale lager. Chilling beer makes it more refreshing, though below 15.5 °C (60 °F) the chilling starts to reduce taste awareness and reduces it significantly below 10 °C (50 °F). Beer served unchilled—either cool or at room temperature—reveal more of their flavours. Cask Marque ,

8322-672: The earliest forms of the drink, are Sahti in Finland, Kvass in Russia and Ukraine , and Bouza in Sudan. 4000 years ago fermented bread was used in Mesopotamia. Food waste activists got inspired by these ancient recipes and use leftover bread to replace a third of the malted barley that would otherwise be used for brewing their craft ale. Beer is measured and assessed by colour, by strength and by bitterness. The strength of modern beer

8436-413: The finished product often is stored for months for comparison, when complaints are received. Brewing is typically divided into 9 steps: milling, malting, mashing, lautering, boiling, fermenting, conditioning, filtering, and filling. Mashing is the process of mixing milled , usually malted , grain with water, and heating it with rests at certain temperatures to allow enzymes in the malt to break down

8550-579: The four largest brewing companies ( Anheuser-Busch InBev , SABMiller , Heineken International , and Carlsberg Group ) controlled 50% of the market The biggest brewery in the world is the Belgian company Anheuser-Busch InBev . In the United States, there were 69,359 people employed in breweries in 2017. This is up from 27,805 in 2001. Some commonly used descriptions of breweries are: Contract brewing –When one brewery hires another brewery to produce its beer. The contracting brewer generally handles all of

8664-707: The freeze-distilling process. The alcohol content of beer varies by local practice or beer style. The pale lagers that most consumers are familiar with fall in the range of 4–6%, with a typical ABVof 5%. The customary strength of British ales is quite low, with many session beers being around 4% abv. In Belgium, some beers, such as table beer are of such low alcohol content (1%–4%) that they are served instead of soft drinks in some schools. The weakest beers are described as 'alcohol-free' , typically containing 0.05% ABV; this compares to low alcohol beers which may contain 1.2% ABV or less, and conventional beers which average 4.4% ABV. The strength of beers has climbed during

8778-482: The goddess Ninkasi . Brewing was initially a cottage industry , with production taking place at home; by the ninth century, monasteries and farms would produce beer on a larger scale, selling the excess; and by the eleventh and twelfth centuries larger, dedicated breweries with eight to ten workers were being built. The diversity of size in breweries is matched by the diversity of processes, degrees of automation , and kinds of beer produced in breweries. A brewery

8892-418: The largest brewery. In 2007, SABMiller surpassed InBev and Anheuser-Busch when it acquired Royal Grolsch , the brewer of Dutch brand Grolsch. In 2008, when InBev (the second-largest) bought Anheuser-Busch (the third-largest), the new Anheuser-Busch InBev company became again the largest brewer in the world. As of 2020 , according to the market research firm Technavio, AB InBev was the largest brewing company in

9006-532: The later years of the 20th century. Vetter 33, a 10.5% ABV (33 degrees Plato , hence Vetter "33") doppelbock , was listed in the 1994 Guinness Book of World Records as the strongest beer at that time, though Samichlaus , by the Swiss brewer Hürlimann, had also been listed by the Guinness Book of World Records as the strongest at 14% |BV. Since then, some brewers have used champagne yeasts to increase

9120-492: The modern brewery and its ability to produce the same beer consistently. The steam engine , vastly improved in 1775 by James Watt , brought automatic stirring mechanisms and pumps into the brewery. It gave brewers the ability to mix liquids more reliably while heating, particularly the mash , to prevent scorching, and a quick way to transfer liquid from one container to another. Almost all breweries now use electric-powered stirring mechanisms and pumps. The steam engine also allowed

9234-730: The natural production of esters and other byproducts, resulting in a "cleaner"-tasting beer. With improved modern yeast strains, most lager breweries use only short periods of cold storage, typically no more than 2 weeks. Some traditional lagers are still stored for several months. Lambic , a beer of Belgium , is naturally fermented using wild yeasts, rather than cultivated. Many of these are not strains of brewer's yeast ( Saccharomyces cerevisiae ) and may have significant differences in aroma and sourness. Yeast varieties such as Brettanomyces bruxellensis and Brettanomyces lambicus are common in lambics. In addition, other organisms such as Lactobacillus bacteria produce acids which contribute to

9348-407: The perception of the beer and can define and accent the character of the style. Breweries offer branded glassware intended only for their own beers as a marketing promotion, as this increases sales of their product. The pouring process has an influence on a beer's presentation. The rate of flow from the tap or other serving vessel, tilt of the glass, and position of the pour (in the centre or down

9462-497: The production process, so that gravity could assist with the transfer of product from one stage to the next. This layout often is preserved in breweries today, but mechanical pumps allow more flexibility in brewery design. Early breweries typically used large copper vats in the brewhouse, and fermentation and packaging took place in lined wooden containers. Such breweries were common until the Industrial Revolution , when better materials became available, and scientific advances led to

9576-441: The proportion between different countries. In Sweden in 2001, 63.9% of beer was sold in cans. People either drink from the can or pour the beer into a glass. A technology developed by Crown Holdings for the 2010 FIFA World Cup is the 'full aperture' can, so named because the entire lid is removed during the opening process, turning the can into a drinking cup. Cans protect the beer from light (thereby preventing spoilage) and have

9690-875: The range of flavours in a beer but cooler temperatures are more refreshing. Most drinkers prefer pale lager to be served chilled, a low- or medium-strength pale ale to be served cool, while a strong barley wine or imperial stout to be served at room temperature. Beer writer Michael Jackson proposed a five-level scale for serving temperatures: well chilled (7 °C or 45 °F) for "light" beers (pale lagers); chilled (8 °C or 46 °F) for Berliner Weisse and other wheat beers; lightly chilled (9 °C or 48 °F) for all dark lagers, altbier and German wheat beers; cellar temperature (13 °C or 55 °F) for regular British ale , stout and most Belgian specialities ; and room temperature (15.5 °C or 60 °F) for strong dark ales (especially trappist beer ) and barley wine . Drinking chilled beer began with

9804-535: The result is often a beer with slightly "fruity" compounds resembling apple, pear, pineapple, banana , plum, or prune, among others. After the introduction of hops into England from Flanders in the 15th century, "ale" came to mean an unhopped fermented brew, while "beer" meant a brew with an infusion of hops. The term ' real ale ' was coined by the Campaign for Real Ale (CAMRA) in 1973 for "beer brewed from traditional ingredients, matured by secondary fermentation in

9918-435: The role of yeast in fermentation was understood, fermentation involved wild or airborne yeasts. A few styles, such as lambics , rely on this method today, but most modern fermentation adds pure yeast cultures . Some brewers add clarifying agents or finings to beer, which typically precipitate (collect as a solid) out along with protein solids, and are found only in trace amounts in the finished product. This process makes

10032-708: The same grain. Darker malts produce darker beers. Nearly all beers use barley malt for most of the starch, as its fibrous hull remains attached to the grain during threshing. After malting, barley is milled, which finally removes the hull, breaking it into large pieces. These pieces remain with the grain during the mash and act as a filter bed during lautering , when sweet wort is separated from insoluble grain material. Other grains, including wheat, rice, oats , and rye , and less frequently, corn and sorghum may be used. Some brewers have produced gluten-free beer , made with sorghum, for those who cannot consume gluten -containing grains like wheat, barley, and rye. Flavouring beer

10146-416: The side) into the glass all influence the result, such as the size and longevity of the head, lacing (the pattern left by the head as it moves down the glass as the beer is drunk), and the release of carbonation . A beer tower or portable beer tap is sometimes used in bars and restaurants to allow a group of customers to serve themselves. The device consists of a tall container with a cooling mechanism and

10260-670: The site of Godin Tepe in the Zagros Mountains of western Iran . Beer is recorded in the written history of ancient Egypt , and archaeologists speculate that beer was instrumental in the formation of civilizations. Approximately 5000 years ago, workers in the city of Uruk (modern day Iraq) were paid by their employers with volumes of beer. During the building of the Great Pyramids in Giza, Egypt , each worker got

10374-575: The sourness. Around the world, many traditional and ancient starch-based drinks are classed as beer. In Africa, there are ethnic beers made from sorghum or millet , such as Oshikundu in Namibia and Tella in Ethiopia. Kyrgyzstan also has a beer made from millet; it is a low alcohol, somewhat porridge-like drink called "Bozo". Bhutan , Nepal, Tibet and Sikkim also use millet in Chhaang ,

10488-404: The spent grains, and sparging , in which extract that remains with the grains is rinsed off with hot water. Boiling the wort ensures its sterility, helping to prevent contamination with undesirable microbes. During the boil, hops are added, which contribute aroma and flavour compounds to the beer, especially their characteristic bitterness. Along with the heat of the boil, they cause proteins in

10602-521: The spring of 2022, using the original recipes. In April 2023, brewing stopped due a royalties dispute between the owners of the Cains brand (Dusanj Brothers) and the micro brewery operator, Mikhail Leisure. Planning permission was granted for a £3.5 million 'BOXPARK' foodhall and events space in January 2023. Intended to replace the existing food and drink hall, the new facility will have ten kitchen units with three internal bars as well as exterior bars and

10716-507: The strongest beer by a Dutch brewery in July 2010. Draught (also spelled "draft") beer from a pressurised keg using a lever-style dispenser and a spout is the most common method of dispensing in bars around the world. A metal keg is pressurised with carbon dioxide (CO 2 ) gas which drives the beer to the dispensing tap or faucet. Some beers may be served with a nitrogen/carbon dioxide mixture. Nitrogen produces fine bubbles, resulting in

10830-411: The strongest beer made is Schorschbräu's 2011 Schorschbock 57 with 57,5% ABV. It was preceded by The End of History , a 55% Belgian ale , made by BrewDog in 2010. The same company had previously made Sink The Bismarck! , a 41% ABV IPA , and Tactical Nuclear Penguin , a 32% ABV Imperial stout . Each of these beers are made using the eisbock method of fractional freezing , in which a strong ale

10944-522: The strongest variety of porter , a dark brown beer popular with the street and river porters of eighteenth century London. Lager is cool-fermented beer. Pale lagers are the most commonly drunk beers in the world. Many are of the " pilsner " type. The name "lager" comes from the German "lagern" for "to store", as brewers in Bavaria stored beer in cool cellars during the warm summer months, allowing

11058-503: The sweetness of the malt; the bitterness of beers is measured on the International Bitterness Units scale . Hops further contribute floral, citrus, and herbal aromas and flavours. They have an antibiotic effect that favours the activity of brewer's yeast over less desirable microorganisms, and aids in " head retention", the length of time that a foamy head created by carbonation will last. The acidity of hops

11172-696: The three main theories are that the word originates in Proto-Germanic * beuzą (putatively from Proto-Indo-European * bʰeusóm ), meaning ' brewer's yeast , beer dregs'; that it is related to the word barley , or that it was somehow borrowed from Latin bibere 'to drink'. Christine Fell , in Leeds Studies in English (1975), suggests that the Old English/Norse word bēor did not originally denote ale or beer, but

11286-408: The volume and variety of beer produced, ranging from small breweries to massive multinational conglomerates, like Molson Coors or Anheuser-Busch InBev , that produce hundreds of millions of barrels annually. There are organizations that assist the development of brewing, such as the Siebel Institute of Technology in the United States and the Institute of Brewing and Distilling in the UK. In 2012

11400-412: The whole fermentation cellar is cooled, conditioning must be done in separate tanks in a separate cellar. Some beers are conditioned only lightly, or not at all. An active yeast culture from an ongoing batch may be added to the next boil after a slight chilling in order to produce fresh and highly palatable beer in mass quantity. Filtering the beer stabilizes flavour and gives it a polished, shiny look. It

11514-512: The world between 2006 and 2010, brewing more than 200 different beers at other breweries. Breweries and football have had a symbiotic relationship since the very beginnings of the game. The English Football League was founded in 1888, and by the next decade several teams already had their own brewery sponsor. In return for their financial support, the breweries were given concessions to sell beer to spectators and advertise their products in stadiums. The most outwardly visible sign of sponsorship are

11628-532: The world is believed to be the German state-owned Weihenstephan brewery in the city of Freising , Bavaria . It can trace its history back to 1040 AD. The nearby Weltenburg Abbey brewery, can trace back its beer-brewing tradition to at least 1050 AD. The Žatec brewery in the Czech Republic claims it can prove that it paid a beer tax in 1004 AD. Early breweries were almost always built on multiple stories, with equipment on higher floors used earlier in

11742-471: The world, with Heineken second, CR Snow third, Carlsberg fourth, and Molson Coors fifth. A microbrewery , or craft brewery , produces a limited amount of beer. The maximum amount of beer a brewery can produce and still be classed as a 'microbrewery' varies by region and by authority; in the US, it is 15,000 US beer barrels (1.8 megalitres; 390 thousand imperial gallons; 460 thousand US gallons)

11856-400: The wort to coagulate and the pH of the wort to fall, and they inhibit the later growth of certain bacteria. Finally, the vapours produced during the boil volatilize off-flavours , including dimethyl sulfide precursors. The boil must be conducted so that it is even and intense. The boil lasts between 60 and 120 minutes, depending on its intensity, the hop addition schedule, and volume of wort

11970-514: Was acquired by the previous owners of Gee Bee Soft Drinks who had sold that business to Princes. The new owners re-established the business under the Robert Cain brand but most of their production was focused on production for supermarkets. Viewing Cains as a route into the UK market, Faxe Bryggeri A/S (now Royal Unibrew) then acquired the company and invested in its ales and local pubs. Unlike its larger competitor Carlsberg, Faxe failed to crack

12084-453: Was agreed by the company's board, giving Cains access to Honeycombe's 109 outlets and a stock market listing. The company was renamed Cains Beer Company PLC and, like Cains Brewery, ceased to function and accrued insurmountable debts within a year. In 2008, the company was placed in administration due to unpaid tax and other debts amounting to £38 million, despite its annual turnover of £65.5 million. Negotiations with its bank failed to reach

12198-409: Was described as a tourism, leisure and retail attraction. The million square foot site would have included a 94-bedroom hotel, cinema, bistro bar, restaurants and an open-plan retail hall for artisan food producers. A food hall opened on the site in 2017. It was open four times a week and operated by Baltic Markets, offering food, drink, entertainment and live events. Brewing restarted at the site in

12312-557: Was different from every brewer. What they did not contain was hops , as that was a later addition, first mentioned in Europe around 822 by a Carolingian Abbot and again in 1067 by abbess Hildegard of Bingen . In 1516, William IV, Duke of Bavaria adopted the Reinheitsgebot (purity law), perhaps the oldest food-quality regulation still in use in the 21st century, according to which the only allowed ingredients of beer are water, hops , and barley- malt . Beer produced before

12426-573: Was flavoured with other plants such as grains of paradise or alehoof . Combinations of aromatic herbs, berries, and even wormwood were combined into aflavouring mixture known as gruit . Some beers today, such as Fraoch' by the Scottish Heather Ales company use plants other than hops for flavouring. and Cervoise Lancelot by the French Brasserie-Lancelot company, Hops contribute a bitterness that balances

12540-430: Was mainly brewed on a domestic scale. The product that the early Europeans drank might not be recognised as beer by most people today. Alongside the basic starch source, the early European beers may have contained fruits, honey, numerous types of plants, spices, and other substances such as narcotic herbs. This mixture was called gruit, where if some were improperly heated could cause hallucinations. The mixture of gruit

12654-599: Was not used to saccharify the rice (amylolytic fermentation); the rice was probably prepared for fermentation by chewing or malting . During the Vedic period in Ancient India , there are records of the consumption of the beer-like sura . Xenophon noted that during his travels, beer was being produced in Armenia . Beer was spread through Europe by Germanic and Celtic tribes as far back as 3000 BC, and it

12768-475: Was reopened by GB Breweries, who became part of Bryggerigruppen in 1991, and in 2002 was sold to Gardener-Shaw for £3.4 million. In 2013 debts exceeding £8m led to the brewery's closure. The Cains brewery was founded by Irishman Robert Cain in 1858 when he bought an established brewery. Cain had begun his brewing career aged 24 when he purchased a pub and brewed his own ales . Within 25 years of founding his brewery, Cain had established 200 pubs, including

12882-491: Was sold to Higsons , who continued to brew Cains ales. In 1985, Higsons was bought by Boddingtons of Manchester . Five years later Boddingtons opted to concentrate on pub ownership and sold all its breweries to Whitbread , at which point the Stanhope Street site was closed. The Stanhope site with its modern canning lines had been heavily invested in under Boddingtons' ownership and appeared an attractive asset. It

12996-422: Was the domain of women, as baking and brewing were seen as "women's work". Breweries, as production facilities reserved for making beer, did not emerge until monasteries and other Christian institutions started producing beer not only for their own consumption but also to use as payment. This industrialization of brewing shifted the responsibility of making beer to men. The oldest, still functional, brewery in
