The Blackened x Rabbit Hole is the 2023 release in Blackened Whiskey’s Masters of Whiskey Series, which was created in partnership with Master Distiller & Blender, Rob Dietrich, and Rabbit Hole Distillery’s Founder & Hall of Fame Whiskey Maker, Kaveh Zamanian. 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 blend is then cask-finished in Calvados casks, bottled at cask strength, and non-chill filtered.
