We hold ourselves to the highest standard when crafting and selecting Jack Daniel’s Single Barrel. In fact, just one out of every 100 barrels are set aside to mature in the highest reaches of our barrelhouses, where dramatic temperature changes cause the color and taste to deepen further. Each barrel is hand-selected for its one-of-a-kind flavor, robust taste, and notes of toasted oak, vanilla, and caramel. It's not easy making a whiskey like Single Barrel. But easy never interested us in the first place.
