I’d like to thank Four Roses and their PR team for providing this review sample with no strings attached
Who says bitching and moaning doesn’t get you anywhere in life? For as long as I’ve been writing for this site—hell, as long as I’ve been a fan of bourbon—I’ve been bending the ear of anyone at Four Roses who would listen about letting people try all these different recipes they keep bragging about. It’s their differentiator. It only makes sense to let people peek behind the curtain.
And in 2023, they finally listened by releasing the Ten Recipe Tasting Kit, filled with 50ml bottles of each recipe. Because yes, I’m sure it was all me—who else could it have been? Their marketing and product development teams? Pssh.
I thought that was the end of things. But no. Starting in early 2025, Four Roses is celebrating the 20th anniversary of their flagship Single Barrel bourbon with the introduction of the Single Barrel Collection. This new lineup features three new 100-proof bourbons—OBSF, OESK, and OESO—alongside the classic OBSV. Each bottle, aged 7-9 years, showcases Four Roses' unique recipes, blending specific mash bills and yeast strains for a distinctive flavor profile. The collection is priced at $49.99 per bottle, with new recipes rotating annually.
"We are incredibly proud of the recognition our flagship Single Barrel has received over the last 20 years, so to be introducing our new Single Barrel Collection in this anniversary year is something truly special," said Four Roses Master Distiller, Brent Elliott.
So, since they sent me a 100ml bottle of each, let’s see how they taste, shall we?
Four Roses Single Barrel Collection, 2025
Purchase Info: These samples were sent to me at no charge for review purposes. The suggested retail price for each bottle is $49.99.
Price per Drink (50 mL): $3.33
Details: Each recipe is aged from 7-9 years old and at 50% ABV.
OBSF
Nose: Sweet and floral, with mint and oak.
Mouth: Crème brûlée, mint, cinnamon, and oak.
Finish: On the longer side of medium, with lingering notes of cinnamon, oak, and especially spearmint.
Thoughts: This is super minty. If you don't like spearmint, skip this one. But if, like me, you rank mint as a top five flavor, you’ll really enjoy it. I like it a lot.
Comparison to the Standard OBSV: OBSF is a mint bomb throughout—on the nose, palate, and finish—compared to OBSV.
OESK
Nose: Almond, cherry, bubblegum, yeast bread, and a touch of mint.
Mouth: Almond, cherry, caramel, vanilla, and baking spice.
Finish: Medium in length and warmth, with rich notes of caramel, vanilla, and baking spice.
Thoughts: I like this one. The almond and cherry notes blend beautifully with the sweet caramel, vanilla, and baking spice. Nothing dominates; it just melds into a delicious whole. My favorite of the three so far.
Comparison to OBSV: OBSV is more floral on the nose, while OESK is richer and more flavorful on the palate, with a longer finish.
OESO
Nose: Caramel and cinnamon.
Mouth: Cinnamon, caramel, and oak.
Finish: Medium in length and warmth, with lingering notes of cinnamon and mint.
Thoughts: Nice and spicy, with lots of cinnamon throughout. The touch of mint on the finish keeps you coming back for more. I like this one.
Comparison to OBSV: Very similar on the nose, but OESO is much spicier on the palate, with more cinnamon. It also has a longer and warmer finish.
Final Thoughts
The OBSF felt a little one-dimensional, with mint taking center stage and only minor support from other notes. The OESK was more well-rounded, with almond and cherry adding depth to the classic bourbon notes of caramel and vanilla. The OESO stood out for its spiciness, with cinnamon shining throughout.
If I had to rank them, it would be:
OESK
OESO
OBSV
OBSF
But your mileage may vary, not only because every palate is different, but also because these are single barrel products, and slight differences are inevitable.
