Heaven Hill distilled this from its standard bourbon mash bill — 78% corn, 10% rye and 12% malted barley — the recipe behind much of the distillery's bourbon lineup, then set it aside to age far longer than most. The twelfth-edition whiskey was drawn from thirty barrels that matured across the upper floors of two separate warehouses: the 4th and 5th floors of Rickhouse A on the Glencoe campus, and the 5th and 7th floors of Rickhouse O at Heaven Hill's main aging site. Upper-floor maturation runs hotter and pulls harder from the wood, which over nineteen years builds the deep oak and concentration this release is known for. It was bottled uncut at its natural barrel strength of 138.2 proof and left non-chill filtered, so nothing was stripped between the barrel and the bottle. The William Heavenhill series has carried Small Batch, Bottled-in-Bond, Barrel Proof and Single Barrel designations across its editions since 2008; this one is a barrel-proof small selection, and the oldest the series has released.

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 William Heavenhill 19 Year?

It is bottled at 138.2 proof, or 69.1% ABV, at full barrel strength and non-chill filtered — the second-highest proof in the William Heavenhill series' history, behind only one of the three proof points offered for the 2014 fourth edition. As a single, one-time edition, that figure is fixed for every bottle. Reviewers have noted it drinks well below its stated strength, with the proof carried by weight and sweetness rather than heat.

Is William Heavenhill 19 Year the oldest release in the series?

Yes. At nineteen years it is the oldest-ever William Heavenhill and the twelfth edition overall in a line that began in 2008. The series features some of Heaven Hill's rarest and most mature stocks, and has ranged across Small Batch, Bottled-in-Bond, Barrel Proof and Single Barrel formats over the years; this one is a barrel-proof bottling, and the most aged the series has offered to date.

What is the mash bill of William Heavenhill 19 Year?

It uses Heaven Hill's standard bourbon mash bill — 78% corn, 10% rye and 12% malted barley — the same recipe (sometimes called "HH Reg") behind Elijah Craig and Evan Williams. What sets this release apart is not the grain but the age and the strength: nineteen years in charred oak, bottled uncut at barrel proof, from a small selection of the distillery's oldest qualifying barrels.
