Jack Daniels Single Barrel Tennessee Whiskey comes from a single barrel that has been individually hand-selected for its unique taste and smooth and aromatic flavour by Jack Daniels Master Distiller and his team of Master Tasters. Once chosen, the whiskey is bottled a single barrel at a time, and never mixed with whiskey from other barrels. The barrels chosen for the storage of Single Barrel come from the uppermost floors of the barrelhouses that dot the hills surrounding the Jack Daniel Distillery. The extremes in temperature these floors experience during the year result in barrels that yield whiskey of unusually bold, robust flavour. Full-bodied with notes of vanilla, toasted oak, and caramel, Jack Daniels Single Barrel has an intense flavour profile and a long rich finish. Each barrel imparts its unique character to the whiskey, and as a consequence, there may be slight variations across bottles that have originated from different barrels.
