Capturing a broad range in one category, American Whiskey refers to any spirit made in America by distilling a mash of fermented grains—typically corn, wheat, rye or barley. American Whiskey must be distilled to no more than 95% alcohol and bottled at 40% or higher. In order to be labeled a straight Whiskey, it also must be aged in white oak barrels for a minimum of two years and not contain any added colors or flavors.
