Refers to American whiskey made from a grain mash, distilled to no more than 80% ABV, and aged for at least 2 years after entering the barrel at an ABV of no more than 62.5%. The only modifications allowed are the addition of water and mixing whiskeys from different barrels—no flavoring or colorants may be added. Straight whiskey can be a blend of different straight whiskeys, as long as they are from the same state. If any whiskeys from the blend are less than 4 years old, an exact age statement is required on the bottle. For more information, see “Instant Expert: Bourbon, Rye and American Whiskey.”
