Blade and Bow is preparing to release a 30-year-old cask-strength bourbon bottled at an extraordinary 82.1% ABV. Because it’s bottled straight from the barrel with little dilution, the whiskey is strong enough to be classified as hazardous material for air travel: federal rules prohibit carrying spirits above 70% ABV in commercial aircraft holds.

Despite its intensity, the bourbon is described as rich and layered rather than simply hot. Its aromas include bergamot, dark berries and singed cedar, while the palate brings ginger, cranberry, molasses and a pronounced mint note. A few drops of room-temperature water can draw out floral aromas and flavors of currant and cassia, making the tasting experience adjustable.

The whiskey comes from the same group of barrels used for last year’s Blade and Bow 30-Year-Old release. The 96 barrels have rested in the historic Stitzel-Weller warehouses since 1993, though the bourbon was distilled at another nearby Kentucky site. To prevent the whiskey from becoming overly oaked during its long aging, the barrels were moved to cooler areas and periodically consolidated as the liquid evaporated.

Only 1,200 bottles remain. Each will cost $2,500 and come in a custom leather box. The release is expected in select U.S. markets in mid-November, with additional bottles offered through limited drops at Stitzel-Weller Distillery during the holiday season.

Blade and Bow is also bringing back a limited number of its original 30-year-old bourbon, bottled at a much lower 109 proof, for its original suggested retail price of $1,200.
