The German beer style that is unfiltered and made with a significant proportion of wheat is Hefeweizen. The German name literally combines “Hefe,” meaning yeast, with “Weizen,” meaning wheat.
Hefeweizen is traditionally cloudy because the beer retains suspended yeast and wheat proteins instead of being filtered clear. Its wheat-rich grist and top-fermenting yeast produce characteristic aromas and flavors, commonly described as banana, clove, bubble gum, or vanilla. These flavors come from fermentation compounds rather than added fruit or spices.
The style is associated especially with Bavaria, although wheat beers are brewed throughout Germany. Hefeweizen is usually highly carbonated and relatively low in hop bitterness, which balances its soft malt sweetness. A filtered version is called Kristallweizen, while a darker wheat beer may be called Dunkelweizen. Stout, bock, and pilsner are different German or European beer styles and do not fit the defining combination of wheat and retained yeast.
