Wheat beer is a beer that is brewe with a significant proportion of wheat. Wheat beers must also contain a certain percentage of malted barley as the enzymes required for starch conversion are not available in wheat alone. The addition of wheat lends wheat beers a light flavour and pale colour. Wheat beers are usually top-fermented (in Germany they have to be by law). Wheat beer is distinguished by its creamy texture and sweet flavour, and some styles have overtones of banana and clove.
