Altbier

Altbier is a style of beer brewed in the Rhineland, especially around the city of Düsseldorf, Germany. It is a copper coloured beer whose name comes from it being top-fermented, an older method than the bottom fermentation of lagers. Altbier is usually a dark, copper colour. It is fermented at a moderate temperature using a top-fermenting yeast—which gives its flavour some fruitiness. Because Altbier is then matured at a cooler temperature, its flavour is more akin to lager beer styles than is the norm for top-fermented beers (such as British pale ale).
