Mellow Corn is produced in accordance with a unique set of regulations that define Straight Corn Whiskey. It is distilled from a mash of at least 80 percent corn and aged for four years in a once-used Bourbon barrel which results in a lighter, straw-colored spirit. After aging, this corn whiskey is bottled at 100 proof. Heaven Hill Distillery is one of the few remaining producers of this unique whiskey.

Mellow Corn was named appropriately. Sweet corn is the prominent note on the nose and palate. The interesting notes tend to appear as the spirit opens in the glass and when the finish begins to fade. Sweet corn, young oak, and cinnamon are constant throughout the tasting process.
