Beer is an alcoholic drink produced by the brewing and fermentation of starches from cereal grains—most commonly malted barley, although wheat, maize (corn), rice, and oats are also used. The fermentation of the starch sugars in the wort produces ethanol and carbonation. Most beer is brewed with hops, which add bitterness and act as a preservative and stabilising agent. Other flavouring agents, such as gruit, herbs, or fruits, may also be used. In commercial brewing, natural carbonation is often 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, China, and Mesopotamia, brewed beer. Since the nineteenth century the brewing industry has been part of most western economies.
Hops are the flowers of the hop plant Humulus lupulus, a member of the Cannabaceae family of flowering plants. They are used primarily as a bittering, flavouring, and stability agent in beer, to which, in addition to bitterness, they impart floral, fruity, or citrus flavours and aromas. Hops are also used for various purposes in other beverages and herbal medicine. The hops plants have separate female and male plants, and only female plants are used for commercial production. The hop plant is a vigorous, climbing, herbaceous perennial, usually trained to grow up strings in a field called a hopfield, hop garden, or hop yard when grown commercially. Many different varieties of hops are grown by farmers around the world, with different types used for particular styles of beer.
Malt is a 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 a coarse meal is known as "sweet meal".
Pale ale is a golden to amber coloured beer style brewed with pale malt. The term first appeared in England 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.
Big Rock Brewery is a Canadian public company and the largest brewery that is based in Calgary, Alberta, Canada. As of March 2020, it was also Canada's largest craft brewery. Additional brewing operations are located in Vancouver, British Columbia; Etobicoke, Ontario; and Liberty Village in Toronto, Ontario. Big Rock distributes a variety of beers and ciders throughout Canada.
Schwarzbier is a dark lager that originated in Germany. It has an opaque, black colour with hints of chocolate or coffee flavours, and is generally around 5% ABV. It is similar to stout in that it is made from roasted malt, which gives it its dark colour.
Beer is one of the oldest human-produced drinks. The first chemically confirmed barley-beer – from the area of Mesopotamia, part of modern-day Iraq – dates back to the 5th millennium BCE. The written history of ancient Egypt and Mesopotamia records the use of beer, and the drink has spread throughout the world; a 3,900-year-old Sumerian poem honouring Ninkasi, the patron goddess of brewing, contains the oldest surviving beer-recipe, describing the production of beer from barley bread, and in China, residue on pottery dating from around 5,000 years ago shows that beer was brewed using barley and other grains.
Horace Tabberer Brown FRS was a British chemist.
The European Brewery Convention (EBC) is an organisation representing the technical and scientific interests of the brewing sector in Europe. The EBC defines itself as the scientific and technological arm of The Brewers of Europe. Among brewers, EBC is perhaps best known for the EBC units measuring beer and wort colour, as well as EBC units for quantifying turbidity in beer. Equally, the EBC congress is recognised globally as a significant meeting event for the world's brewing, malting and beer fermentation scientists and technologists, taking place every two years.
The United States Brewers' Association was a trade organization that existed from 1862 to 1986.
Lager is a type of beer 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 word for "storage", as the beer was stored before drinking, traditionally in the same cool caves in which it was fermented.
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.
The Institute of Brewing and Distilling (IBD) is an industry trade association for brewers and distillers, both in the United Kingdom and internationally. The IBD had its headquarters at Clarges Street in London London until 2014 at which time the Institute moved to its current location in Curlew Street, south of the River Thames.
When drinking beer, there are many factors to be considered. Principal among them are bitterness, the variety of flavours present in the beverage and their intensity, alcohol content, and colour. Standards for those characteristics allow a more objective and uniform determination to be made on the overall qualities of any beer.
Beer in Scotland is mostly produced by breweries in the central Lowlands, which also contain the main centres of population. Edinburgh and Alloa in particular became noted for the export of beer around the world in the 19th century.
The chemical compounds in beer give it a distinctive taste, smell and appearance. The majority of compounds in beer come from the metabolic activities of plants and yeast and so are covered by the fields of biochemistry and organic chemistry. The main exception is that beer contains over 90% water and the mineral ions in the water (hardness) can have a significant effect upon the taste.
Cornelius O'Sullivan, FRS was an Irish brewer's chemist.
The Research Institute of Brewing and Malting (RIBM) in Czech - was founded in 1887 and since 1994 It has been a joint-stock company. It is one of the oldest scientific research institutes in the Central European region.
Charles Finkel is a designer, entrepreneur, artist and founder of Bon-Vin, Merchant du Vin, and The Pike Brewing Company in Seattle, Washington. Charles began marketing wines from small family owned California wineries in the 1970s and was the first to market the wines of Washington state throughout the country. In an article in Wines and Vines Magazine in 1970, Finkel was the first to use the term "boutique wines" to describe small, family owned wines of quality.
