Origins & Craftsmanship

Distilled in Lawrenceburg, Kentucky, the Four Roses Single Barrel lineup showcases barrels selected for exceptional character and consistency. Each bottle comes from an individually chosen barrel, not blended with others, allowing the unique interplay of grain bill and yeast to shine.

The OBSF label denotes a specific recipe within Four Roses’ systematic mash bill and yeast family:

• O — Mash bill with high corn (60 %), low rye (35 %), and malted barley (5 %)

• B — The second yeast strain used in fermentation

• S — Indicates a second yeast development profile

• F — The final of the two yeast strains

This particular recipe, OBSF, is known for its rich, layered fruit character with a gentle knit of baking spices — a profile that translates beautifully in single-barrel selections. The whiskey is matured in new charred American oak barrels, where it develops depth, oak influence, and refined spice nuance over time. Bottling at 100 proof preserves flavor intensity while ensuring smooth balance and approachability.
