These are refreshing, fast-maturing beers that are lightly hopped and show a unique banana-and-clove yeast character. These beers often don’t age well and are best enjoyed while young and fresh. The version mit hefe is served with suspended yeast; the krystal version is filtered for excellent clarity. The character of a krystal weizen is generally fruitier and less phenolic than that of the weissbier mit hefe. May be known as hefeweizen, particularly in the United States.
