Heaven Hill just launched the first release in its new Heaven Hill Heritage Collection which will feature one of the distillery’s six unique mashbills for release. The inaugural whiskey is a barrel-proof bourbon bottled at 118.2 proof and made using the distillery’s core bourbon mash bill of 78 percent corn, 10 percent rye, and 12 percent malted barley. The label says the whiskey is 17 years old, but that’s indicative of the youngest whiskey in the bottle, which also includes 19 and 20-year-old bourbon (the exact breakdown: 28 percent 20-year-old barrels, 44 percent 19-year-old barrels, 28 percent 17-year-old barrels).
