This three bottle bundle brings together the Four Roses Single Barrel Collection, a celebrated lineup introduced in 2025 to mark the 20th anniversary of the distillery's flagship single barrel bourbon. Four Roses is unique among Kentucky distilleries for producing ten distinct bourbon recipes, achieved by combining two separate mashbills with five proprietary yeast strains, each contributing its own signature character. For two decades, the widely available 100 proof Single Barrel featured only the OBSV recipe, but the Single Barrel Collection finally opens up that vault, releasing additional recipes in the same accessible 100 proof, single barrel format. This set features three of those expressions, each aged between seven and nine years and bottled at 100 proof. OBSF is built on the high rye B mashbill of 35 percent rye and 60 percent corn with the herbaceous F yeast, delivering bright rye, apple, vanilla, clove, and cocoa. OESO uses the E mashbill of 20 percent rye and 75 percent corn with the O yeast, known for rich red fruit, vanilla, brown sugar, and delicate oak. OESK pairs that same E mashbill with the spice driven K yeast, one of the most sought after Four Roses recipes, offering baking spices, mellow oak, tea leaves, and caramel. Tasting all three side by side is a masterclass in how a single distillery's recipes can diverge so dramatically, making this bundle a perfect gift or a rewarding exploration for any bourbon enthusiast who wants to experience the breadth and craftsmanship of Four Roses in one collection.
