Jack Daniel’s Single Barrel 2020 Special Release Barrel Proof Rye is a Tennessee Rye that features the distillery’s newest grain bill since Prohibition. Made up of 70% rye, 12% malt and 18% corn, the barrels for it were aged in the highest areas of a barrel house, “resulting in what’s officially described as “a deep copper hue with robust aromas of deep smoke, raisin, rich caramel and toasted fruit; boasting tastes of molasses, sawn oak and bold rye spices with a peppery finish.”
