The legendary Old No. 7 is the soul of American whiskey. Its distinct, smooth blend comes from rolling and mellowing the freshly distilled whiskey drop by drop through 10 feet of sugar maple charcoal; then it's matured in American Oak barrels hand-made by Jack Daniel's themselves. The only major distiller in the world to make their own barrels. Each batch is made from marrying 170 barrels from all levels of the barrelhouses to achieve consistent colour and taste.
