Four Roses Distillery, Lawrenceburg, Kentucky

Four Roses Single Barrel

Kirin Brewery Company (Four Roses Distillery, est. 1888)

Four Roses Single Barrel is the product of the most obsessive production system in bourbon. While every other distillery works from a single mash bill and a single yeast strain, Four Roses developed two distinct mash bills and five proprietary yeast strains — creating ten unique recipes, each with its own flavor fingerprint. The standard Single Barrel uses recipe OBSV: the high-rye mash bill (35% rye — among the highest in Kentucky) paired with the V yeast strain, which contributes delicate fruit and cream. At 100 proof, it has the structure to showcase every layer of that complexity. The result is a bourbon that tastes like it was engineered by someone who couldn’t stop asking “what if?” — because it was.
