Our high in small grain Kentucky Straight Bourbon Whiskeys are offered as a Single Barrel - Bottled in Bond. Two special releases in one bottle! The Single Barrel selection offers nuances only premium cooper select barrels can create from their toasting and using 18-month-old air-dried staves. After all, the barrels impart a large part of the flavor. In addition, the Bottled in Bond gives you assurance the Bourbon was properly distilled, aged between 5-6 years and bottled by us under the supervision of the U.S. Government at 100 proof.
