Tasting Notes: In the ever forward march of the Jack Daniel's brand, the rerelease of Jack Daniel's Barrel Proof Single Barrel Rye is another reason to celebrate. This particular bottling clocks in at 132.3 proof and packs a punch. Completely mature oak, fruit, and leather notes along with baking spices round out the nose. On the palate, mouthwatering dollops of rye spice, with a deep woodsy bitterness slathered with sweet caramel and toffee. This is rich, powerful, literally mouthwatering juicy rye.
