Lager

Lager (/ˈlɑːɡər/) is a type of beer brewed and conditioned at low temperature.^[1] Lagers can be pale, amber, or dark. Pale lager is the most widely consumed and commercially available style of beer.^[2] The term "lager" comes from the German word for "storage", as the beer was stored before drinking, traditionally in the same cool caves^[3] in which it was fermented.

As well as maturation in cold storage, most lagers are distinguished by the use of Saccharomyces pastorianus (Saccharomyces pastorianus is a yeast used industrially for the production of lager beer, and was named in honour of Louis Pasteur by the German Max Reess in 1870), a "bottom-fermenting" yeast that ferments at relatively cold temperatures.
