St. Louis-based Luxco has launched its limited release, ultra-premium bourbon whiskey series called Blood Oath, featuring a different variant or Pact each year.

The inaugural Pact, named Blood Oath Pact No. 1, is made with a special blend of three Kentucky Straight Bourbon Whiskeys.

The bottle has a custom, eco-friendly natural cork and is labelled with a heavy certificate-style paper stock.

Each bottle’s label will also feature Rempe’s signature, along with the specific bottle’s creation date and the story behind the pact.

John Rempe, Director of Corporate Research and Development at Luxco and creator of Blood Oath said: "I have the luxury of not being tied down to one specific distillery, so I sampled many bourbons to find the perfect mix to make Blood Oath Pact No. 1.

"This product is an exquisite union of three well-bred bourbons with various age statements and mash bills. The first, a spicy bourbon with a mash bill favoring rye, barrel aged for a subtle woodiness. The second is a smooth, wheated bourbon and the third is a full-bodied, more experienced, oaky bourbon with a rye-based mash. Each of these complement the other and none overpower the palate, creating an amazing bourbon."

Bottled by hand at 98.6 proof, the new limited edition whiskey is available in limited quantities nationally in 750ml bottles, with a suggested price of $89.99.

The bourbons in Pact No. 1 range from 6 to 12 years old.

After Pact No. 1, Pact No. 2 will be released in 2016 and will feature an entirely new combination.
