What Exactly Is Malt?
Malt is a grain (usually barley) that has been moistened, allowed to germinate, and then dried in a kiln. This process releases enzymes that convert the starch in the grain into sugars that can be used in brewing and distilling. Depending on the degree of kilning, the malt may have a light, pale color or a darker, more caramelized flavor. Malt is a crucial ingredient in the manufacturing of various types of alcohol, including beer, whiskey, and malt vinegar.
