German

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. As well as maturation in cold storage, most lagers are distinguished by the use of Saccharomyces pastorianus, a "bottom-fermenting" yeast that ferments at relatively cold temperatures. Until the 19th century, the German word Lagerbier (de) referred to all types of bottom-fermented, cool-conditioned beer in normal strengths. In Germany today, it mainly refers to beers from southern Germany, either "Helles" (pale) or "Dunkles" (dark). Pilsner, a more heavily hopped pale lager, is most often known as "Pilsner", "Pilsener", or "Pils". Other lagers are Bock, Märzen, and Schwarzbier. In the United Kingdom, the term commonly refers to pale lagers derived from the Pilsner style.
