BLACKENED Whiskey's Master Distiller & Blender, Rob Dietrich, teamed up with Rabbit Hole Distillery's Founder & Hall of Fame whiskey maker, Kaveh Zamanian, to create BLACKENED x Rabbit Hole, the 2023 release of the Masters of Whiskey Series. This limited-edition expression is crafted from a 13-year old straight Tennessee bourbon whiskey, which is 64% corn/36% rye, and Rabbit Hole Heigold High Rye Double Malt Kentucky Straight bourbon, 70% corn/25% malted rye/5% malted barley. The bourbon whiskey blend is then finished in Calvados apple brandy casks, bottled at cask strength, and non-chill filtered. A bouquet of apple butter, rhubarb, honey-suckle, graham cracker, and macadamia nut. On the palate, ripe pear, cinnamon stick, smoky campfire, field clover, honey, and black walnut.
