Four Roses Single Barrel Bourbon – Recipe OBSF is a rare and highly distinctive release from the iconic Kentucky distillery, renowned for its unique ten-recipe system that sets it apart from every other bourbon producer. This bottling comes from the “B” mash bill, made with 60% corn, 35% rye, and 5% malted barley, paired with the “F” yeast strain, celebrated for its delicate herbal character. The result is a bourbon that combines the bold spice of a high-rye mash with the refined herbal notes imparted by the F yeast, offering one of the most distinctive and complex flavor profiles in the Four Roses lineup.

As a single barrel release, OBSF is drawn from one carefully chosen cask, ensuring that each bottle reflects the individuality of its barrel while carrying the distillery’s signature smoothness. Bottled at 100 proof, it strikes a perfect balance between strength and drinkability, showcasing rich layers of caramel, oak, and baking spice, lifted by subtle herbal and floral undertones. Collectors and enthusiasts prize the OBSF recipe for its rarity and uniqueness, making it a sought-after addition to the Single Barrel program and a true expression of Four Roses’ mastery of blending and recipe diversity.
