Kaiyo has built a quiet reputation for doing things differently in the Japanese whisky space, and The Unicorn 10 Year Old is perhaps the clearest statement of that intent. This is a blended malt — no grain whisky in sight — bottled at 46% ABV without chill filtration. At £132, it sits in a competitive bracket where you're up against well-established Scotch single malts and a growing field of credible Japanese releases. The question isn't whether it's good. It's whether it justifies the price in a crowded market.
What makes Kaiyo interesting from an industry perspective is their positioning. They've carved out a niche with Mizunara oak finishing — Japanese oak that's notoriously difficult to cooperage and eye-wateringly expensive to source. It's a genuine point of differentiation in a category where many producers are still trading on mystique rather than substance. The Unicorn, with a decade of maturation behind it, represents their more serious offering, and the 46% bottling strength suggests they want you to actually taste what's in the bottle rather than diluting it into something inoffensive.
Tasting Notes
I don't have detailed tasting notes to share on this particular bottling, so I won't fabricate them. What I can tell you is that a 10-year-old blended malt at 46% from Kaiyo's stable is going to lean into that house style — expect the influence of Mizunara oak to be present, which typically brings a distinctive incense-like, sandalwood character that you simply don't get from American or European oak. The non-chill-filtered presentation at this strength means texture and body should be well-preserved. This is a whisky that's been built to deliver flavour, not to look pretty in a highball.
The Verdict
At 8.3 out of 10, The Unicorn earns its marks for ambition and execution. The ten-year age statement gives it credibility in a Japanese whisky market that's been plagued by age-statement shortages and NAS releases of questionable provenance. Kaiyo has been transparent about their approach, and the blended malt designation tells you they're working with quality components rather than padding things out with column-still grain. Is £132 a lot of money? Yes. But look at what else occupies that shelf space in the Japanese category — you'll find younger, lower-strength bottles asking for more. In the current market, this actually represents reasonable value for a genuine Japanese blended malt with an age statement. It's not a unicorn in the mythical sense. It's a unicorn because finding a well-priced, age-stated Japanese whisky of this quality is becoming increasingly rare.
Best Served
Pour this neat in a Glencairn at room temperature and give it ten minutes to open up. The 46% strength can handle a few drops of water if you want to soften things, but I'd suggest tasting it undiluted first — at this ABV, it's already in a comfortable drinking range. If you're feeling adventurous, try it in a Japanese-style mizuwari with cold mineral water at a 1:2 ratio. It's a format that lets the subtler oak notes come forward without drowning them. Save the highball for your everyday drinkers — this one deserves more attention than that.
