Four Roses is one of Kentucky's most celebrated distilleries, renowned for its use of two mash bills and five proprietary yeast strains — a combination that produces ten distinct bourbon recipes. The Single Barrel Barrel Strength OBSO expression represents the pinnacle of that craft: a 10 year old bourbon bottled directly from a single barrel at full proof, with no dilution and no chill filtration. The OBSO recipe pairs a high-rye mash bill (O) with a yeast strain (S) that contributes delicate fruit and floral notes, resulting in a bourbon of remarkable complexity and intensity.

Finish: Long, warming, and deeply satisfying with lingering spice and oak
