Corn whiskey

American whiskey made with a mash consisting of a minimum of 80% corn and distilled to a maximum of 80% ABV. Corn whiskey may be matured in used or uncharred oak containers, but does not require barrel aging. It is subject to regulatory requirements, setting it apart from moonshine. A variant known as straight corn whiskey is aged in used or uncharred oak barrels for 2 or more years.
