Beer
Beer is an alcoholic drink made by fermenting grain, usually malted barley, with water and yeast, often flavored and preserved with hops.
Mashing: A brewing step that mixes crushed malt with warm water to convert starches into fermentable sugars. Mashing extracts the sugars yeast later ferments into alcohol.
Malted barley: Barley grain that has been germinated and dried to develop enzymes and brewing flavors. Its enzymes convert grain starch into sugars during mashing.
Lager: Beer fermented with bottom-fermenting yeast, typically at cooler temperatures, and often conditioned cold. Lagers contrast with ales in yeast strains, fermentation conditions, and common flavor profiles.
History of beer: The history of brewing and drinking fermented grain beverages across human societies. Beer’s ingredients and methods developed over millennia alongside settled agriculture.
Brewing: The process of making beer by extracting grain sugars, fermenting them, and preparing the resulting drink. Beer is the central product of brewing, whose methods also support other fermented beverages.
Wort: The sugary liquid extracted from malted grain before fermentation. Wort is the immediate product of mashing and the starting liquid for fermentation.
Water chemistry: The study of dissolved substances and chemical properties in water. Minerals in brewing water affect mash performance and the perception of bitterness.
Ale: Beer fermented with top-fermenting yeast, generally at warmer temperatures than lager. Ales are a broad beer family with fermentation traditions distinct from lagers.
Godin Tepe: An archaeological site in western Iran with evidence associated with ancient beer production. Chemical traces in vessels from Godin Tepe provide early evidence of beer.
Beer glassware: Drinking vessels designed or selected to serve beer and shape its aroma, appearance, and foam. Glass shape and service influence how beer’s carbonation and aromas are experienced.
