We do things a little differently around here and that s what gives Jack Daniel s its distinctive character. We Charcoal Mellow our whiskey drop by drop, then let it age in our own handcrafted barrels. And we don t follow a calendar. Our Tennessee Sippin Whiskey is ready only when our tasters say it is. We use our senses, just like Jack Daniel himself did. In fact, more than a century later, our Tennessee Whiskey is still judged the same way. By the way it looks. By the way it smells. And of course, by the way it tastes. Every drop of Jack Daniel's Tennessee Whiskey, the best-selling whiskey in the world, is distilled at Lynchburg, Tennessee's Jack Daniel Distillery, the nation's first registered distillery, which opened its doors in 1866. The finest corn, rye, and barley malt are used to create this premium product, which is then blended with iron-free water from the distillery's on-site Cave Spring. In order to achieve our distinctive smoothness, Jack Daniel's is then charcoal-mellowed drop by drop through 10 feet of sugar maple charcoal. Last but not least, Jack Daniel's is aged in handcrafted white oak barrels that we have made.
