Things are done a little differently around the Jack Daniels distillery and that's what gives Jack his distinctive character. Jack is charcoal mellowed, drop by drop, then aged in his own hand coopered barrels. The still-masters don't follow a calendar. Jack is ready only when the distillery's dedicated tasters say it is. They use their five senses, just like Jack Daniel himself did. In fact, more than a century later, Jack Daniel's 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.
