Recipe OESK: The Spiced Corner of the Ten Recipes
Four Roses builds every bourbon from ten recipes — two mash bills crossed with five proprietary yeast strains — and OESK pairs the corn-rich, softer Mash Bill E with yeast K, the strain prized for gentle spice. For the Single Barrel Collection, Master Distiller Brent Elliott bottled individual recipes at 100 proof so drinkers can taste exactly what one recipe does on its own: here, warmth and baking spice over mellow oak.

Tasting Notes
The distillery's notes lead with full-bodied baking spices, then mellow oak, earthy tea leaves and rich caramel — a warm, rounded single barrel with the spice carried by the yeast rather than the rye.
How to Enjoy
Neat in a Glencairn to follow the spice, or with a few drops of water to open the caramel. It also makes a plush, spice-forward Old Fashioned — go easy on the bitters and let recipe K talk.
