Beer. Beer is an alcoholic beverage 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 in the beer. [1]
Beer chemistry. Weighing hops. 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. [1]
The fermented beer will have some residual sugar which will raise the SG, the alcohol content will lower the SG. The difference between the SG of the wort before fermentation and the SG of the beer after fermentation gives an indication of how much sugar was converted to alcohol and CO 2 by the yeast.
An alcoholic beverage (also called an adult beverage, alcoholic drink, strong drink, or simply a drink) is a beverage containing alcohol (ethanol). Alcoholic drinks are typically divided into three classes— beers, wines, and spirits —and typically their alcohol content is between 3% and 50%. Many cultures have a distinct drinking culture ...
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.
Wort (/ ˈwɜːrt /) is the liquid extracted from the mashing process during the brewing of beer or whisky. Wort contains the sugars, the most important being maltose and maltotriose, [1] that will be fermented by the brewing yeast to produce alcohol. Wort also contains crucial amino acids to provide nitrogen to the yeast as well as more ...
In the United States, beer is manufactured in breweries which range in size from industry giants to brew pubs and microbreweries. [1] The United States produced 196 million barrels (23.0 GL) of beer in 2012, and consumes roughly 28 US gallons (110 L) of beer per capita annually. [2] In 2011, the United States was ranked fifteenth in the world ...
Malt liquor is a type of mass market beer with high alcohol content, most closely associated with North America. Legally, it often [where?] includes any alcoholic beverage with 5% or more alcohol by volume made with malted barley. [citation needed] In common usage, it refers to beers of high alcohol content, generally above 6%, which are made ...
