Jack Daniels Old No. 7 is a Tennessee whiskey made from a mash of corn, rye, and malted barley, filtered through charcoal (the Lincoln County Process) before aging in charred American oak barrels. It has iconic notes of rich caramel, toasted vanilla, and sweet oak, with a warm, mellow character. The finish is smooth and lingering, with a hint of spice and gentle dryness.
