Beer is one of the oldest and most widely consumed alcoholic drinks in the world, and the third most popular drink overall after water and tea. It is produced by the brewing and fermentation of starches, mainly derived from cereal grains—most commonly from malted barley, though wheat, maize (corn), rice, and oats are also used. During the brewing process, fermentation of the starch sugars in the wort produces ethanol and carbonation in the resulting beer. Most modern beer is brewed with hops, which add bitterness and other flavours and act as a natural preservative and stabilizing agent. Other flavouring agents such as gruit, herbs, or fruits may be included or used instead of hops. In commercial brewing, the natural carbonation effect is often removed during processing and replaced with forced carbonation.
Brewing is the production of beer by steeping a starch source in water and fermenting the resulting sweet liquid with yeast. It may be done in a brewery by a commercial brewer, at home by a homebrewer, or communally. Brewing has taken place since around the 6th millennium BC, and archaeological evidence suggests that emerging civilizations, including ancient Egypt and Mesopotamia, brewed beer. Since the nineteenth century the brewing industry has been part of most western economies.
Malt is germinated cereal grain that has been dried in a process known as "malting". The grain is made to germinate by soaking in water and is then halted from germinating further by drying with hot air.
Sake, also spelled saké, is an alcoholic beverage of Japanese origin made by fermenting rice that has been polished to remove the bran. Despite the name Japanese rice wine, sake, and indeed any East Asian rice wine, is produced by a brewing process more akin to that of beer, where starch is converted into sugars which ferment into alcohol, whereas in wine, alcohol is produced by fermenting sugar that is naturally present in fruit, typically grapes.
Homebrewing is the brewing of beer on a small scale for personal, non-commercial purposes. Supplies, such as kits and fermentation tanks, can be purchased locally at specialty stores or online. Beer was brewed domestically for thousands of years before its commercial production, although its legality has varied according to local regulation. Homebrewing is closely related to the hobby of home distillation, the production of alcoholic spirits for personal consumption; however home distillation is generally more tightly regulated.
Pale ale is a golden to amber coloured beer style brewed with pale malt. The term first appeared around 1703 for beers made from malts dried with high-carbon coke, which resulted in a lighter colour than other beers popular at that time. Different brewing practices and hop quantities have resulted in a range of tastes and strengths within the pale ale family.
Wheat beer is a top-fermented beer which is brewed with a large proportion of wheat relative to the amount of malted barley. The two main varieties are German Weizenbier and Belgian witbier; other types include Lambic, Berliner Weisse, and Gose.
In brewing and distilling, mashing is the process of combining a mix of ground grains – typically malted barley with supplementary grains such as corn, sorghum, rye, or wheat – known as the "grain bill" with water and then heating the mixture. Mashing allows the enzymes in the malt to break down the starch in the grain into sugars, typically maltose to create a malty liquid called wort.
Beer in Belgium varies from pale lager to amber ales, lambic beers, Flemish red ales, sour brown ales, strong ales and stouts. In 2018, there were approximately 304 active breweries in Belgium, including international companies, such as AB InBev, and traditional breweries including Trappist monasteries. On average, Belgians drink 68 liters of beer each year, down from around 200 each year in 1900. Most beers are bought or served in bottles, rather than cans, and almost every beer has its own branded, sometimes uniquely shaped, glass. In 2016, UNESCO inscribed Belgian beer culture on their list of the intangible cultural heritage of humanity.
Beer has been brewed in England for thousands of years. As a beer brewing country, it is known for top fermented cask beer which finishes maturing in the cellar of the pub rather than at the brewery and is served with only natural carbonation.
Beer styles differentiate and categorise beers by colour, flavour, strength, ingredients, production method, recipe, history, or origin.
Beer is one of the oldest drinks humans have produced. The first chemically confirmed barley beer dates back to the 5th millennium BC in modern-day Iran, and was recorded in the written history of ancient Egypt and Mesopotamia and spread throughout the world.
Lautering is the beer brewing process that separates the mash into clear liquid wort and residual grain. Lautering usually consists of three steps: mashout, recirculation, and sparging.
Mash ingredients, mash bill, mashbill, or grain bill are the materials that brewers use to produce the wort that they then ferment into alcohol. Mashing is the act of creating and extracting fermentable and non-fermentable sugars and flavor components from grain by steeping it in hot water, and then letting it rest at specific temperature ranges to activate naturally occurring enzymes in the grain that convert starches to sugars. The sugars separate from the mash ingredients, and then yeast in the brewing process converts them to alcohol and other fermentation products.
Lager is beer which has been brewed and conditioned at low temperature. Lagers can be pale, amber, or dark. Pale lager is the most widely consumed and commercially available style of beer. The term "lager" comes from the German for "storage", as the beer was stored before drinking – traditionally in the same cool caves it was fermented in.
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 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.
Beer is produced through steeping a sugar source 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 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.
Sour beer is beer which has an intentionally acidic, tart, or sour taste. Traditional sour beer styles include Belgian lambics, gueuze and Flanders red ale, and German gose and Berliner Weisse.
Bent Paddle Brewing Company is a microbrewery located in Duluth, Minnesota.
A tower brewery is a distinct form of brewery, identified by its external buildings being arranged in the form of a vertical tower.
