. Historically, Bavarian Weißbier was either brewed with a large share of wheat malt (which was a ducal privilege in Bavaria) or from air-dried pale barley malt only (which was a common drink amongst poor people). It is well known throughout Germany, though better known as Weizen ("Wheat") outside Bavaria. The terms ''Hefeweizen'' ("yeast wheat") or Hefeweißbier refer to wheat beer in its traditional, unfiltered form. The term ''Kristallweizen'' (crystal wheat), or ''Kristallweißbier'' (crystal white beer), refers to a wheat beer that is
