Jack Daniel's Bonded is Jack's time-honored recipe of 80% corn, 12% malted barley. and 8% rye. Hand selected barrels to create their unique and particular characteristics of deeper color, flavor, and aroma, which bring a darker, richer, and more oak-forward character to Jack Daniel's Bonded. At 100 proof, this Tennessee Whiskey is layered with notes of caramel, rich oak, and spice giving way to a pleasantly lingering finish.
