Jack Daniel's is a brand of Tennessee whiskey and the top-selling American whiskey in the world. This is the soul of American whiskey. It is worth mentioning that Jack Daniel’s whiskey is not bourbon, in production methods at least. There is, however, one key difference. Its distinct and unique taste comes from refining and mellowing the freshly distilled whiskey drop by drop through 10 feet of sugar maple charcoal. The distilled whiskey is then 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. Interesting fact - every drop of the world's biggest selling whiskey comes from a single source, Lynchburg, Tennessee.
