Four Roses Single Barrel Recipe OBSK Bourbon Whiskey

Four Roses Single Barrel Recipe OBSK Bourbon Whiskey – Single Barrel Kentucky Straight Bourbon | Four Roses Distillery, Lawrenceburg, Kentucky

Four Roses Single Barrel Recipe OBSK Bourbon Whiskey is an exceptional and distinctively expressive expression from Four Roses Distillery in Lawrenceburg, Kentucky — one of the most celebrated and historically significant bourbon distilleries in the world, and the only Kentucky distillery to use a combination of two mash bills and five proprietary yeast strains to produce ten distinct bourbon recipes. This unique production philosophy gives Four Roses an unparalleled ability to craft expressions of extraordinary complexity and individuality — and the Single Barrel line is where that philosophy reaches its most pure and expressive form.

The OBSK recipe designation is the key to understanding what makes this expression so distinctive. In Four Roses’ recipe coding system, each letter carries specific meaning: O = Four Roses Distillery, B = the high-rye mash bill (60% corn, 35% rye, 5% malted barley), S = straight whiskey, and K = the “K” yeast strain — one of Five Roses’ five proprietary yeasts, known for imparting a rich, full-bodied spice character with notes of baking spice, dark fruit, and a warming complexity that makes OBSK one of the most sought-after and characterful recipes in the Four Roses portfolio. Bottled as a single barrel, this expression delivers the full, unblended character of one exceptional OBSK cask — a bourbon of genuine individuality and exceptional quality.

How to Enjoy

Four Roses Single Barrel Recipe OBSK Bourbon Whiskey is best enjoyed neat or with a few drops of still water in a quality Glencairn or rocks glass to fully appreciate the distinctive OBSK recipe character — the high-rye spice, dark fruit, and warming complexity that the “K” yeast strain delivers. A small addition of water can open up additional layers of fruit and baking spice. For cocktails, OBSK excels in spirit-forward, whiskey-centric serves — try it in a Spiced Old Fashioned (Four Roses OBSK, Demerara syrup, Angostura bitters, orange peel) where the high-rye spice character shines beautifully, or a Manhattan (Four Roses OBSK, sweet vermouth, Angostura bitters, Luxardo cherry) for a rich and satisfying stirred cocktail. For food pairings, Four Roses OBSK pairs beautifully with dark chocolate and spiced desserts, aged cheddar and hard cheeses, BBQ and smoked meats, dried fruit and nut confections, and charcuterie boards.

Frequently Asked Questions (FAQ)

What does OBSK mean in Four Roses’ recipe system?

Four Roses uses a four-letter recipe coding system to identify each of its ten distinct bourbon recipes. For OBSK: O = Four Roses Distillery (Lawrenceburg, Kentucky), B = the high-rye mash bill (60% corn, 35% rye, 5% malted barley), S = straight whiskey (aged a minimum of 2 years), and K = the “K” proprietary yeast strain, which is known for imparting a rich, full-bodied spice character with notes of baking spice, dark fruit, and warming complexity. The OBSK recipe is one of the most sought-after in the Four Roses portfolio — prized for its bold, spice-forward character and the depth that the high-rye mash bill and “K” yeast combination produces.

How does Four Roses Single Barrel OBSK differ from standard Four Roses Single Barrel?

The standard Four Roses Single Barrel is always bottled from the OBSV recipe — the high-rye mash bill with the “V” yeast strain, known for its delicate fruit and floral character. The OBSK recipe uses the same high-rye mash bill but with the “K” yeast strain instead — producing a bolder, spicier, and more full-bodied character with richer dark fruit and baking spice notes. OBSK is typically available through Four Roses’ private barrel selection program and is sought out by enthusiasts who want a more assertive and complex expression than the standard Single Barrel.
