Wheat beer is one of the oldest beer styles, dating back thousands of years. Wheat malt and unmalted flaked wheat impart unique characteristics to these styles such as increased body, a creamy mouthfeel, improved foam stability, and haze. There are many varieties of wheat beer that range in color from white to black, and alcohol content from 3-10% ABV. Within this diversity of styles, most wheat beer styles are united by the flavors imparted by specific yeast strains, notably banana (isoamyl acetate) and clove (4-vinyl-guaiacol, or 4VG).
