Jack Daniel s No. 27 Gold Note: Introducing Jack Daniel's No. 27 Gold Tennessee Whiskey. A rich, exquisitely refined and distinctively finished expression of our original Old No. 7 Tennessee Whiskey. Crafted to the same uncompromising standards as Jack Daniel's Old No. 7, our Jack Daniel's No. 27 Gold earns its name from the double barreling and double mellowing. It is extra matured in golden-hued maple barrels and twice charcoal mellowed.
