The German-style hefeweizen is straw to amber in color and made with at least 50 percent malted wheat. The aroma and flavor of a weissbier comes largely from the yeast and is decidedly fruity (banana) and phenolic (clove). “Weizen” means “wheat” and “hefe” means “yeast.” There are multiple variations to this style. Filtered versions are known as “Kristal Weizen” and darker versions are referred to as “Dunkels,” with a stronger, bock-like version called “Weizenbock.” This is commonly a very highly carbonated style with a long-lasting collar of foam.
