Barrell's Private Release Series is an exercise in blending while maintaining a single barrel-like scale controlled entirely by hand and palate. The goal is to always maximize the best attributes of each component. Every ounce of every ingredient changes the overall character of these blends, as does the barrel in which each is aged. For that reason, these barrels take months to polish and perfect. The unique nature of each ingredient and the barrel they are married in makes every bottling singularly special.

Each release of Private Release Whiskey is a unique blend of Kentucky Whiskey, the oldest being 18 years old. Once created, these blends are married in single casks, many of which were previously used for other spirits and/or wines. For batch BH32, Kentucky whiskey was blended and married in a Malmsey Madeira Barrel.
