Composed of the classic Jack Daniel's rye mash, the same as has been since 2017, this 70% rye, 18% corn, and 12% malted barley whiskey is charcoal-filtered and comes with all of the classic JD trimmings that we know and love. Aged in new charred oak barrels for five years, and finished in heavily toasted 'Heritage barrels' for an additional two years, fans of the Special Release Heritage barrel will appreciate this densely layered whiskey.
