George Dickel Superior Signature Recipe 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.

Jack Daniel's Sinatra Select is a 90-proof Tennessee whiskey offering a bold, smooth, and rich flavor profile, with notes of oak, caramel, vanilla, and spice, a result of aging in special "Sinatra barrels" with deep grooves that expose the whiskey to extra toasted oak. Its aroma features a balance of sweet and smoky tones, leading to a robust palate with hints of honey and butterscotch, and a lingering finish with tobacco and baking spices
