William Heavenhill 15 Year Old 4th Release Bourbon Whiskey 105.4 Proof

105.4 proof. 15 years. 4th Release. William Heavenhill — the fourth annual edition of Heaven Hill’s prestige aged program, presenting 15 years of Kentucky maturation at an accessible proof point that prioritizes complexity over intensity.

At 105.4 proof, the 4th Release is in a very different register from the 12 Year 134.4-proof Small Batch also in the collection — the 15 Year’s lower proof allows the full three decades of additional maturity (compared to a young bourbon) to express through a more approachable presentation. Many of Heaven Hill’s most celebrated ultra-aged releases (Parker’s Heritage, this program) operate at accessible proof points for exactly this reason.
