Jack Daniel’s Triple Mash is a Bottled-in-Bond whiskey, which must be distilled by a single distiller during a single distillation season, matured in a government bonded warehouse for at least four years, and bottled at 100 proof. Barrels are hand-selected for their characteristics of deeper color, flavor, and aroma, which deliver a darker, richer, and more oak-forward character. It’s a big, bold Tennessee Whiskey at 100 proof with layered notes of caramel, rich oak, and spice giving way to a pleasantly lingering finish.
