KO Distilling Signature Series 10 Year HAZMAT High Rye Bourbon 142.4 Proof 750ml

The KO Distilling Signature Series 10 Year HAZMAT Bourbon celebrates 10 years of partnership between KO Distilling of Manassas, Virginia and Prestige-Ledroit Distributing Co. In 2015, KO laid down high rye bourbon (75% corn, 21% rye, 4% malted barley) distilled in Indiana into 80 Kelvin Cooperage Char 3 barrels and aged it in Manassas. By late 2025 only 9 barrels remained — each at or above 140 proof — and they were bottled as this HAZMAT micro-batch of just 430 bottles at 142.4 proof (71.2% ABV). The nose is rich and syrupy with thick cherry, maple whipped cream, singed citrus, and mature oak; the palate is creamy and sticky with cherry, maple, chocolate, and baking spice; the finish lingers with creamy oak, boozy cherries, hickory smoke, and a long tingle of spice.
