Weißbier literaty means white beer in Germany, because it was originally made when the brewing method of regular light-colured lagers now known as Helles had not yet been invented and all other Munich beers were dark. Outside Bavaria a Weißbier is usually called a Weizenbier (wheat beer) or simply a Weizen. Additionally, dark varieties of Weißbier are known as Dunkel Weissbier or a Dunkelweizen.
A traditional Weissbier glass holds half a litre of beer plus extra room for foam. Pouring a Weißbier requires a bit of practice, since the foam will otherwise likely overflow or be flat.
