Jack Daniel''s® Single Barrel is finely crafted and bottled from a single barrel which has been individually hand selected by our master tasters for its unique taste, smooth and aromatic character. The barrels chosen for Single Barrel come from the uppermost floors of the barrelhouses; roughly only 1 of every 100 barrels make the cut. The extremes in temperature these floor experience during the year, result in barrels which yield whiskey of the most robust flavors, smoothness and aroma.
