This extraordinary release follows Jack's traditional Tennessee Whiskey process, using the signature 80% corn, 12% malted barley, and 8% rye mash bill, charcoal-mellowed drop by drop. What sets this expression apart is its unique aging journey - beginning in the upper floors of the barrelhouse before being relocated to the cooler lower ricks to extend maturation. Batch 1 comprises carefully selected barrels bottled at their natural strength of 126.3 proof (63.15% ABV), presenting the whiskey in its purest form. With only a limited number of bottles available, this release bridges Jack Daniel's storied past with its present mastery.
