Four Roses Single Barrel Recipe OESK Bourbon Whiskey

A richly aromatic and elegantly balanced single-barrel bourbon, Four Roses Single Barrel OESK (100 proof) showcases the distillery’s unique blending of mash bill and yeast strain to deliver layered fruit, spice, and oak notes with remarkable harmony. This expression is smooth yet expressive — robust enough for contemplative sipping yet refined enough to highlight subtlety and nuance.

Origins & Craftsmanship

Hailing from Lawrenceburg, Kentucky, Four Roses is renowned for its methodical approach to bourbon production, combining five distinct mash bills with two proprietary yeast strains to create ten unique recipes. Each recipe reflects a specific structural and aromatic profile based on grain interaction and yeast character.

The OESK designation breaks down as follows:

• O — Mash bill comprised of 60% corn, 35% rye, and 5% malted barley

• E — A specific yeast strain in the Four Roses fermentation family

• S — Denotes the second yeast development profile used

• K — The second yeast strain in the pair used for this batch

This combination produces a spirit that marries spicy complexity with fruit-accented warmth. Bottled as part of the revered Single Barrel series, each OESK expression comes from a barrel selected for outstanding character, then bottled at 100 proof (50% ABV) — preserving depth and aromatic clarity without dilution. The result is a bourbon that reveals both intensity and refinement in every sip.
