Beer soup (German: Biersuppe, Alsatian: Biersupp, Czech: Pivní polévka) is a soup which is usually roux-based and made with beer.[1] In medieval Europe, it was served as a breakfast soup,[2] sometimes poured over bread.
Variations on the recipe use the starchiness of potato as a thickener.[3] The Sorbian version is sweet, with cream and raisins added.
