Bardstown Bourbon Company has become one of the most talked-about names in American whiskey over the last few years, and for good reason. They've built a reputation on transparency, collaboration, and letting the liquid do the talking. This particular bottle — an 8-year-old single barrel selected exclusively for The Whisky Exchange — is the kind of release that gets bourbon hunters on both sides of the Atlantic paying attention. At 64.6% ABV, this is cask strength in the truest sense: no water added, no apologies made.
Let's talk about what that 64.6% means in practical terms. That's a seriously high proof, well above the legal maximum barrel entry proof of 62.5% ABV (125 proof) that defines bourbon production. The fact that this has actually gained proof during its eight years in the barrel tells you something important about the warehousing conditions — this bourbon was almost certainly aged in a higher, hotter position where water evaporates faster than alcohol. That's classic Kentucky climate at work, and it tends to produce bourbons with real density and concentration of flavour.
Eight years is a solid age statement for bourbon. It's long enough for the oak to have done serious work — drawing out vanillins, caramels, and tannins through those seasonal temperature swings — but not so long that the wood dominates everything. For a single barrel release, age matters even more because there's nowhere to hide. There's no blending here to smooth out rough edges or create consistency. What you're tasting is one barrel's entire story, start to finish.
The single barrel aspect is worth emphasising. The Whisky Exchange selected this specific cask, which means someone tasted through multiple barrels and chose this one as the best representation for their customers. That curation process adds genuine value — you're not just buying bourbon, you're buying someone's informed judgement about which barrel was firing on all cylinders.
Tasting Notes
I'd recommend spending some real time with this one before forming any conclusions. At 64.6%, your first sip neat will be dominated by ethanol heat if you're not careful. Add water gradually — even a few drops will open this up considerably. Given the age, proof, and single barrel nature, expect the kind of bold, oak-forward character that high-proof aged bourbons are known for: think rich caramel, baking spices, dark fruit, and a good hit of charred oak. But every single barrel is its own animal, and that's half the fun.
The Verdict
At £125, this sits in competitive territory for single barrel, cask strength bourbon in the UK market. You're paying a premium for the exclusivity and the age, but I think it's justified. Eight-year-old cask strength single barrels from a producer with Bardstown's track record don't come cheap, and the fact that this was hand-selected for a retailer as reputable as The Whisky Exchange gives me confidence in the quality. This is a bourbon for people who want to taste something with genuine character and individuality — not another blended-to-a-profile crowd-pleaser. I'm giving it a 7.8 out of 10. It's a strong pour that delivers on its promises, and the kind of bottle that rewards patience and repeated visits.
Best Served
Pour it neat first and give it five minutes in the glass before nosing. Then add water — seriously, don't be a hero at 64.6%. A few drops at a time until the heat recedes and the flavour opens up. If you want to mix with it, this proof makes it an absolute powerhouse in an Old Fashioned. Use a good demerara sugar cube, two dashes of Angostura, and an orange peel expressed over the top. The high ABV means the bourbon stands up to the dilution from the ice and still delivers full flavour. That said, at £125 a bottle, I'd save most of it for sipping.
