Jack Daniels Bonded is Jacks time-honored recipe of 80% corn, 12% malted barley, and 8% rye. Barrels were hand selected for their unique and particular characteristics of deeper color, flavor, and aroma, which bring a darker, richer, and more oak-forward character to Jack Daniels Bonded. It is a big, bold Tennessee Whiskey at 100 proof with layered notes of caramel, rich oak, and spice giving way to a pleasantly lingering finish.
