It was once a privilege reserved for Jack Daniel's Master Distiller. Exploring the nuances of whiskey from a single barrel. Today, connoisseurs around the world can savor this experience on their own. Jack Daniel's Single Barrel Tennessee Whiskey, the world's first charcoal mellowed single barrel Tennessee Whiskey, allows whiskey aficionados to sample the work of individual barrels, comparing the subtle differences imbued by each barrel's unique oak wood and aging experience. In fact, just one out of every 100 barrels are set aside to mature in the highest reaches of Jack Daniel's 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. When you try Jack Daniel's Single Barrel for the first time, note the barrel number. Try to detect the different nuances -- a strong caramel or vanilla presence, perhaps; or maybe the toasted oak flavor or fruit drawn from the barrel wood captures your tastebuds.
