Beer grain is an essential ingredient in the production of beer. BARLEY (6 letters) and malt (4 letters) are two of the most common grains used to make beer. BARLEY is a cereal grain that is used to provide the fermentable sugars needed for the production of beer. Malt is made from BARLEY and other grains that have been germinated and dried. Both BARLEY and malt are essential components of beer, providing the flavor, color, and body of the beer.
