Jack Daniel's Single Barrel Barrel Proof is bottled straight from an individual barrel at cask strength, without dilution, so each bottling is unique in strength and character. Barrels are chosen from the Lynchburg barrelhouses for their bold, robust profile. Expect deep caramel, toasted oak, vanilla and rich baking spice with a long, warming finish. Try it neat first, then add a few drops of water to open it up.
