St. Louis-based Luxco announced the launch of its limited release, ultra-premium bourbon series, Blood Oath.

This craft bourbon whiskey series will highlight a different variant, or “Pact,” each year. The inaugural Pact, named Blood Oath Pact No. 1, consists of a blend of three Kentucky Straight Bourbon Whiskeys, blended and bottled by hand.

According to the company, the blend consists of a spicy bourbon with a mash bill favoring rye, barrel aged for a subtle woodiness; a smooth, wheated bourbon; and a full-bodied, more experienced, oaky bourbon with a rye-based mash. The bourbons in Pact No. 1 range from 6 to 12 years old.

The debut combination, bottled at 98.6 proof, is available in limited quantities nationally in 750ml bottles, with a suggested price of $89.99.

After Pact No. 1’s limited edition run, Pact No. 2, consisting of an entirely new combination, will subsequently be released in 2016.
