Barrel Brothers: Comparing Whiskey Caviar’s Private Select Four Roses OBSO & OESO Picks

When it comes to high-proof, flavor-packed bourbon, few names resonate like Four Roses. With ten distinct recipes and a cult following for their single barrel releases, Four Roses offers an unmatched opportunity to experience how yeast and mash bill variations create dramatically different flavor profiles. Whiskey Caviar is proud to present two standout Private Select Single Barrels: the bold and spicy OBSO and the lush, fruit-forward OESO. Each one reflects a unique character—and together, they make for a fascinating side-by-side tasting.

Available now at Whiskey Caviar.

🔥 The High-Rye Heat: Four Roses OBSO Single Barrel (123.6 Proof)

Crafted from Four Roses’ high-rye mash bill and the “O” yeast strain (known for rich fruit), the OBSO expression is built for bourbon lovers who appreciate boldness. This 123.6-proof barrel packs a punch with layers of cherry, leather, and spice. Aged in Warehouse MW (Barrel 3-3L), this Private Select hits all the right notes for a high-proof sipper that doesn't sacrifice complexity.

Flavor Highlights:

  • Bright cherry, cinnamon bark, and toasted brown sugar

  • Leather and dark fruit on the mid-palate

  • Long, spicy finish with cocoa and dry oak

🍒 The Fruit-Forward Charmer: Four Roses OESO Single Barrel (118.4 Proof)

From a lower-rye mash bill with the same “O” yeast strain, the OESO barrel delivers a smoother, fruit-driven profile that showcases elegance at 118.4 proof. Aged in Warehouse AN (Barrel 51-4L), this pick opens with juicy plum and maple, followed by creamy vanilla and gentle spice. It’s a layered pour that highlights the softer, silkier side of barrel-strength bourbon.

Flavor Highlights:

  • Plum, maple syrup, and rose petal on the nose

  • Creamy vanilla and toasted coconut

  • A long, rounded finish with dried fruit and soft tannins

🥃 Which One’s for You?

Both barrels are bottled at full strength and non-chill filtered, allowing the true essence of each recipe to shine through. Whether you’re after OBSO’s spicy power or OESO’s velvety richness, you’re in for a genuine bourbon experience.

To maximize your tasting, pour into a Glencairn glass to focus the aromas and reveal each bottle’s layered complexity.

Final Thoughts:

These Whiskey Caviar Private Selects are limited, single-barrel expressions—once they’re gone, they’re gone for good. Whether you add one to your collection or grab both for a head-to-head tasting, you’re securing a piece of Four Roses craft at its finest.
