Charcoal mellowing is at the heart of what separates our Tennessee Whiskey from bourbons. Jack insisted that every drop of our whiskey should be slowly trickled through ten feet of sugar maple charcoal, a process which takes three to five days to complete. The charcoal acts as a filter, removing impurities and bitterness, mellowing the whiskey so its natural flavor shines. For Gentleman Jack, we introduce a second charcoal-mellowing process after maturation known as doublemellowing, meant to hone the whiskey into a subtly-sophisticated offering. The result of this double-mellowing is the exceptionally smooth, well-balanced and refined whiskey of Gentleman Jack.
