This expression represents a specific type of bourbon whiskey. It signifies a product distilled and bottled at its original distillation strength, typically exceeding the standard 80 proof (40% ABV). The “single barrel” designation indicates that the contents of the bottle originate from a single, individual aging barrel, rather than a blend of multiple barrels. This contrasts with blended bourbons, which combine whiskey from various barrels to achieve a consistent flavor profile. Full proof, in this context, highlights the whiskey’s undiluted nature straight from the barrel.
The value in a bourbon of this kind lies in its unique flavor profile. Each barrel matures differently, imparting distinct characteristics to the whiskey it holds. Factors like the barrel’s wood type, char level, location in the rickhouse (warehouse where barrels are stored), and the length of aging all contribute to the individual character of the final product. By bottling from a single barrel at its original proof, the distillery offers consumers a chance to experience the purest and most unadulterated expression of their craft. Furthermore, understanding the historical methods involved in crafting such a spirit enriches appreciation for the time and dedication necessary to bring the product to market.
