George Dickel Superior No. 12 Whisky is crafted from a mash of 84% corn, 8% rye and 8% malted barley, which are milled and mashed before being fermented with a proprietary strain of yeast. Following fermentation, the whisky is distilled and then matured in casks that have been charred with a #2 char on the heads and a #4 char on the staves (the degree of charring within a cask is measured on a scale of one to four, with a #1 char referring to casks that have been lightly toasted, and a #4 char referring to casks that have been charred so heavily that the interior resembles an alligator hide). Once the whisky has matured, it is chilled to 40°F and then mellowed through sugar maple charcoal. This process is rather unusual (most distilleries that mellow whisky through charcoal do so prior to maturing it in oak barrels) and contributes a hint of smoky sweetness to the whisky.

George Dickel No. 12 Whisky has an aroma of rich oak, charcoal and sweet smokiness that gives way to notes of maple syrup, buttered bread and smoke. The finish is deep and complex, with touches of roasted corn, charcoal, citrus and raisins.

George Dickel earned the Gold Medal from the Beverage Testing Institute in 2012 and 2013. The whisky also earned a score of 95 points from the Ultimate Spirits Challenge in 2013, which named it the Best Tennessee Whisky.
