Four Roses OBSF — a cask strength single barrel expression at 61.7% ABV (123.4 proof), presenting the OBSF recipe: the O distillery code (Four Roses), B distillery location, S mash bill (high rye, 60% corn / 35% rye / 5% malted barley), and F yeast strain (herbal, light spice with mint and anise character).
The OBSF recipe is one of Four Roses’ ten unique recipe combinations, pairing the high-rye Small mashbill with the F yeast strain known for its herbal, minty, and lightly floral character — a distinctly different profile from the more common OBSK (K yeast, spicy and full-bodied) and OESV (V yeast, fruity and creamy) expressions.
