Jack Daniel's Old No. 7 Tennessee Whiskey is one of the world's best-selling whiskeys with a smooth character and flavor, true to Mr. Jack Daniel's original recipe. This American whiskey is made from the finest corn, rye and barley malt mixed with the iron-free water that flows from the Cave Spring right on grounds of the distillery. From there, Jack Daniel's Tennessee Whiskey is charcoal mellowed, drop by drop, through 10 feet of sugar maple charcoal, which imparts the distinct smoothness of this best-in-class whiskey. Finally, Jack Daniel's Tennessee Whiskey is matured in handcrafted, charred white oak barrels until the tasters decide it's ready.
