Four Roses Single Barrel Recipe OBSK Bourbon Whiskey
100 proof (50% ABV) | 750mL | Aged 7–9 years | 2026 Single Barrel Collection — Four Roses Single Barrel Recipe OBSK is the spice-forward star of the 2026 Single Barrel Collection: one of Four Roses' ten distinct bourbon recipes, bottled as a single barrel at full 100 proof. The code tells the story — O: Four Roses Distillery, B: high-rye mash bill (60% corn, 35% rye, 5% malted barley), S: straight bourbon, K: the proprietary yeast strain that brings slight spice.
Four Roses builds its whole portfolio from just two mash bills and five yeast strains, and the annual Single Barrel Collection (launched 2025) rotates recipes to national shelves so drinkers can taste beyond the flagship OBSV Single Barrel. OBSK — "Recipe 2" — is the high-rye, baking-spice entry: "enjoy the rich rye tones before seamlessly transitioning into flavors of allspice, cocoa and cinnamon," per the distillery, "a bright, oaky finish makes this an expression hard to forget." The official profile: nose of allspice, cocoa, vanilla, and cinnamon; palate of rye spice and caramel; a bright, rich finish. Distilled and aged in Lawrenceburg, Kentucky — available to order online at Del Mesa Liquor.
