Made from 80% corn, 12% rye and 8% malt, a small beer is made that distills once, giving the whiskey weight. A doubler under the still re-distils vapour from the beer heater giving softness to the spirit. Filtering slowly through 10 feet of maple charcoal takes fusel oils from the whiskey and adds smokiness. Barrel maturation in American oak smooths the spirit, adding caramel tones. It is the charcoal filtration method that makes this Tennessee whisky.
