Blood Oath Pact 10 is a masterful union of two well-bred ryed bourbons, each complementing the others in this, our 10th edition pact. In honor of this double-digit milestone, we ve achieved a double cask finish. The first finish was perfected in Cabernet Franc barrels, while the second was refined in merlot casks two varietals often used together in high-end red wine blends.
