Augusta Distillery Buckner's Single Barrel Bourbon 15 Year Barrel 88 140.6 Proof Hazmat

140.6 proof. 15 years. Hazmat. Barrel 88. Augusta Distillery Buckner’s — a 15-year expression at 140.6 proof carrying the Hazmat designation, which identifies American whiskey bottled above 140 proof — the threshold above which special shipping regulations apply due to the elevated alcohol concentration.

The Hazmat designation is a proof milestone: 140+ proof American whiskey triggers specific transport and labeling requirements under DOT regulations, placing Barrel 88 in the same regulatory tier as the Buckner’s 13-year Barrel 110 (150 proof) and the Rare Character xWASxHEREx (145.28) in the collection. At 15 years, Barrel 88 is two years older than the 13-year expressions, delivering additional oak integration and depth alongside the extreme proof concentration.
