American Whiskey

American whiskey must be distilled and aged in America, and must be made from a mash bill (the mixture of grains used to make the whiskey) that contains at least 51% of their named grains. Grains commonly used in American whiskey production include rye, barley, corn, and wheat. Among other regulations, American whiskey (except for corn whiskey, which does not need to be aged at all) must be aged in new, charred oak containers, which can impart a distinct flavor and color to the whiskey.
