[[Lager]] is cool-fermented beer. [[Pale lager]]s are the most commonly drunk beers in the world. Many are of the "[[pilsner]]" type. The name "lager" comes from the German "lagern" for "to store", as brewers in Bavaria stored beer in cool cellars during the warm summer months, allowing the beers to continue to ferment, and to clear any sediment.<ref>[http://www.beerhunter.com/documents/19133-000255.html Beerhunter.com] {{Webarchive |url=https://web.archive.org/web/20160906031705/http://www.beerhunter.com/documents/19133-000255.html |date=6 September 2016 }} Michael Jackson, ''BeerHunter'', "The birth of lager", 1 March 1996.

Lager typically undergoes primary fermentation at {{convert|7|–|12|C|F}}, and then a long secondary fermentation at {{convert|0|–|4|C|F}} (the lagering phase). During the secondary stage, the lager clears and mellows. The cooler conditions inhibit the natural production of [[ester]]s and other byproducts, resulting in a "cleaner"-tasting beer.<ref>[http://www.eurekalert.org/pub_releases/2008-09/cshl-bbb090308.php Eurekalert.org] {{Webarchive|url=https://web.archive.org/web/20110607144649/http://www.eurekalert.org/pub_releases/2008-09/cshl-bbb090308.php |date=7 June 2011 }} Gavin Sherlock, EurekAlert, ''Brewing better beer: Scientists determine the genomic origins of lager yeasts'', 10 September 2008.

Some traditional lagers are still stored for several months.<ref>{{cite web |last1=O'Rourke |first1=Tim |title=Science: Warm maturation and cold stabilisation |url=https://www.brewersjournal.info/science-warm-maturation-and-cold-stabilisation/ |website=Brewers Journal |access-date=22 November 2024 |date=15 June 2022}}</ref>
