Because no two barrels can occupy the exact same space within the barrelhouse, the whiskey that emerges from each barrel naturally holds a difference in character. One barrel may develop with more hints of vanilla and caramel. Another may mature with more toasted oak notes. Evidence of this unique background is the bottles neckband indicating its rick, barrel number and individual bottling date. This is the beauty of Jack Daniels Single Barrel. Each and every barrel provides a singular experience for those who enjoy it.
