The choice of a hop variety used in beer brewing depends on the beer style. For instance, lager styles use hop varieties with a low alpha acid content (such as Saaz and Hallertauer) while IPA styles use hop varieties with a high alpha acid content (such as Cascade, Centennial and Chinook).
A 16th-century brewery Brewing is the production of beer by steeping a starch source (commonly cereal grains, the most popular of which is barley) 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 ...
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 the chemical composition of the local water. [14]
Old English: Beore 'beer'. In early forms of English and in the Scandinavian languages, the usual word for beer was the word whose Modern English form is ale. [1] 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).
A thermometer in use to test the temperature of beer. Gravity, in the context of fermenting alcoholic beverages, refers to the specific gravity (abbreviated SG), or relative density compared to water, of the wort or must at various stages in the fermentation. The concept is used in the brewing and wine-making industries.
Beer fermenting at a brewery. Zymology, also known as zymurgy, [a] is an applied science that studies the biochemical process of fermentation and its practical uses. Common topics include the selection of fermenting yeast and bacteria species and their use in brewing, wine making, fermenting milk, and the making of other fermented foods.
Just as the composition of the beer (proteins, hops, yeast residue, filtration) affects a beer's head, the amount of lacing is also closely controlled by the specific composition of the beer, and beer connoisseurs can tell much by the lacing, though strictly speaking beer quality is not readily apparent by the head or the lacing.
