Jack Daniels Single Barrel Rye is a far cry from good Old No. 7 and thus will appeal to not only fans of that bottling but rye drinkers in general. What you have here is a 94 proof bottling which according to Jack Daniels is crafted using a unique 70 percent rye 18 percent corn and 12 percent malted barley grain bill giving the whiskey a clean sweet tone at the tip of the tongue with a more distinct and slightly shorter than other Single Barrel offerings. Rye also uses the same cave spring water from the Jack Daniels Hollow proprietary yeast and charcoal-mellowing process thats been used in the distillerys 150-year-old Tennessee Whiskey recipe. From there the liquid enters a charred White American Oak barrel crafted at Jack Daniels very own cooperage and set to age in the upper regions of the barrelhouse. In this resting place the whiskey is exposed to the extreme temperature variations that a Lynchburg Tennessee season brings.
