Wathen's Single Barrel Bourbon Kentucky Straight Bourbon Whiskey is one of those bottles that tends to fly under the radar, and honestly, that's part of its charm. At 47% ABV, it sits in a sweet spot — enough proof to carry serious flavour without the burn that scares off newer bourbon drinkers, and enough backbone to hold its own in a cocktail. The "single barrel" designation here is what really caught my attention. Every barrel is its own little universe, shaped by where it sat in the warehouse, how the seasons treated it, and the particular character of the wood. That variability is a feature, not a bug.
What to Expect
As a Kentucky Straight Bourbon, Wathen's has to meet some non-negotiable legal standards that actually tell you a lot about what's in the glass. We're talking at least 51% corn in the mashbill, aged in new charred oak barrels, and matured for a minimum of two years in Kentucky — though the colour and body on this one suggest it's spent considerably longer than the legal minimum resting in wood. The NAS (no age statement) approach lets the brand pick barrels based on taste rather than a number on the label, and at 47% ABV it hasn't been diluted down to the bare minimum the way some budget bourbons are. That extra proof means more of the barrel's influence comes through intact.
Single barrel bourbons are where you really get to appreciate what warehouse placement does to a spirit. Barrels stored higher up in a rickhouse experience more dramatic temperature swings — hotter summers push the whiskey deeper into the wood, pulling out more caramel, vanilla, and char. Lower floors tend to produce something gentler. Without knowing exactly where Wathen's pulls from, I'd say the proof point and the richness of the liquid suggest barrels that have had plenty of interaction with their oak. You can expect the classic Kentucky bourbon profile here: corn sweetness up front, baking spice from the rye or wheat in the mashbill, and that signature charred oak finish that good bourbon delivers.
The Verdict
At £59.95, Wathen's Single Barrel sits in competitive territory. You're paying a premium over standard blended bourbons, but you're getting something with genuine individuality. The single barrel format means your bottle won't taste exactly like anyone else's, and for a whiskey enthusiast, that's half the fun. The 47% ABV shows confidence — they haven't watered this down to maximise yield. It drinks like a bourbon that respects your palate. I'm giving it a 7.8 out of 10. It delivers exactly what a well-made single barrel Kentucky bourbon should: character, warmth, and enough complexity to keep you coming back to the glass. It's not trying to reinvent the wheel, and it doesn't need to. The wheel works just fine when it's built properly.
Best Served
This is a bourbon that works beautifully neat with a few drops of water to open it up, but where it really shines is in an Old Fashioned. The 47% ABV means it won't get lost behind the sugar and bitters — it'll push through and keep the drink bourbon-forward. Two ounces of Wathen's, a barspoon of demerara syrup, two dashes of Angostura, and an expressed orange peel. Stir it over a large ice cube for about 30 seconds. The single barrel character gives the cocktail a depth that blended bourbons simply can't match. If you're feeling adventurous, try it in a Manhattan with a quality sweet vermouth — the proof carries the whiskey through the mix without losing its identity.
