This release came out of one narrow window. Heaven Hill filled all 133 barrels in December 2005 and pulled every one of them from the third floor of Rickhouse 1I, which is a far tighter selection than an eighteen-year-old bourbon usually represents — most long-aged releases are assembled across fill dates and warehouse positions to even out what individual barrels do over two decades. A third-floor position sits low enough in a Kentucky rickhouse to moderate the summer swings that drive the oak extraction higher up, which is consistent with a release bottled at 120 proof rather than at the strength the barrels came out at. The mash bill is the distillery’s traditional bourbon recipe, 78% corn, 12% malted barley and 10% rye, one of the six traditional American whiskey mash bills Heaven Hill maintains and rotates through the series.

Every bottle sold through Midnight Whiskey is sourced as an authentic, sealed product and inspected before it ships. Orders are packed with padded, glass-rated handling and require an adult signature (21+) on delivery; we do not ship to anyone unable to verify legal drinking age.

What proof is the Heaven Hill Heritage Collection 18 Year?

Heaven Hill bottled the 2024 Heritage Collection 18-Year-Old at 120 proof, which is 60% ABV. Heaven Hill's release states the bottling strength as 120 proof and does not describe this edition as barrel proof, which distinguishes it from the 2026 edition in the same series.

When was the Heaven Hill Heritage Collection 18 Year distilled?

Heaven Hill produced the whiskey for the 2024 Heritage Collection 18-Year-Old in December 2005 and drew all of it from the third floor of Rickhouse 1I. That is an unusually narrow selection for an eighteen-year-old bourbon: one fill month and one warehouse floor. Heaven Hill prints the warehouse site, production date and mash bill percentages on the packaging as a signature of the collection.

How does the 2024 Heaven Hill Heritage Collection compare to the 2026 release?

Both are Kentucky straight bourbon from Heaven Hill's traditional mash bill, but they differ in every other respect the producer states. The 2024 edition carries an 18-year age statement at 120 proof, drawn from a single December 2005 fill on one warehouse floor. The 2026 edition carries a 22-year age statement at barrel proof, 129.2, from barrels filled across three months of 2003 on two floors of a different rickhouse.
