Biersuppe is a typically German soup, that in all probability dates back several centuries. It is further testimony to the German love of beer. In Germany, it is usually made with dark beer, which has a very low alcohol content. Mostly it is eaten hot, usually preceding a cold evening meal. When made with lager beer, it is best eaten well chilled.
