The Jack Daniel's Aged Series highlights the modern-day, world-class, whiskey-making expertise of Jack Daniel Distillery while honoring the distillery’s past. The ingredients and whiskey-making process of Jack Daniel's 12-year-old Tennessee Whiskey remain the same as Jack Daniel’s Tennessee Whiskey: 80% corn, 12% malted barley and 8% rye. Evolving Jack’s past aged-stated whiskey process, these Tennessee whiskey barrels age in the upper floors of their barrelhouse before they are methodically relocated to the lower ricks to extend the aging process. The extreme weather variation in the barrelhouse’s different locations combine with longevity in the handmade oak barrels to create Jack Daniel's Tennessee Whiskey’s intense, unique character at 107 proof.
