Weissbier (“white beer”), also known as wheat beer, is made from wheat and barley. Weissbier has an original gravity of between 11 and 14 percent and an alcohol content of 5 to 6 percent. In former times, there was only Weissbier, because top-fermented yeasts could also be used for brewing beer in summer. Top-fermented yeasts, which work at a temperature of around 20 degrees, are pushed up to the surface due to the carbon dioxide produced, hence the name top-fermented. Weissbier is probably the most Bavarian of all beers.
