Four Roses Single Barrel Bourbon OBSF 750ml

The OBSF Recipe — Four Roses Single Barrel

Four Roses is unique among Kentucky distilleries in using two mash bills and five proprietary yeast strains to create ten distinct bourbon recipes — each identified by a four-letter code. The OBSF recipe combines the high-rye "B" mash bill with the "F" yeast strain, known for producing a bold, spicy, and full-bodied character with a rich fruit complexity. Bottled as a single barrel, every bottle is a unique expression of that specific cask.

Tasting Notes

• Nose: Bold and fruity. Ripe fruit and spice lead with a caramel sweetness and the distinctive character of the OBSF recipe.
• Palate: Full-bodied and complex. Fruit, spice, and caramel interplay with a warming oak influence and a depth that speaks to single barrel selection.
• Finish: Long and spicy. Fruit and oak spice linger with a bold, satisfying close.
