Barrell Craft Spirits' Private Reserve line is renowned for being one of the most comprehensive and meticulous blending programs in American spirits. The team at Barrell has created over 100 different blended whiskeys, each made up of a unique proportion of aged whiskeys and finished in various types of vessels, despite being produced in little more than single-barrel quantities.

Among the Private Reserve releases, the CH48 stands out for its distinct aging process, which is rare in craft spirits production. This whiskey, based on an 18-year-old Kentucky whiskey, was aged in used Calvados barrels, resulting in a captivating and alluring quality that complements the robustness of the old whiskey.
