The standard line of Gaiaflow Shizuoka Distillery, in Yaizu, Shizuoka — UNITED S. Among Japanese craft distilleries, this one sits in an unusually specific spot.
The core idea: Shizuoka runs two pot stills in parallel — still W is one of the very few direct wood-fired stills operating today, and still K was relocated from the closed Karuizawa distillery. UNITED S blends the two new-make streams in different ratios to express what they call the Shizuoka terroir.
Shizuoka water + two stills
Operating since 2016, Shizuoka uses meltwater from the Mount Fuji and Southern Alps watersheds, with some Shizuoka-grown barley in the mash bill. UNITED S is a recurring seasonal release (summer / winter) bottled by Gaiaflow Distilling Co. ABV around 50.5%, primarily a 500 mL format.
Vanilla and honey on the nose, then fresh malt and a thin thread of wood-fired smoke at the back. The palate is sweet and delicate, with a woody spice and a touch of bitterness that reads as the K-still side coming through. The finish is medium. At 50.5% it stays drinkable neat; a few drops of water lift the fruit aromas.
"Karuizawa's stills are still alive"
The closed Karuizawa Distillery (1955–2011) is now a ghost producer whose remaining bottles fetch enormous prices at auction. When Karuizawa shut down, part of its equipment was sold off, and one of those stills ended up in Shizuoka — running under the name "K". So while UNITED S is not "Karuizawa's spirit," it is, in a literal sense, "Karuizawa's still still making spirit." That historical thread alone gives the bottle a value beyond just its taste.
Craft distilleries are interesting in how each one designs its own terroir. Shizuoka's design — two stills + watersheds from Fuji + Shizuoka barley — is genuinely different from anyone else's blueprint.
Gaiaflow Shizuoka Distillery
Operating since 2016
Located in Yaizu, Shizuoka. Founded and run by Taiko Nakamura via Gaiaflow Distilling Co. Mash water comes from the Mount Fuji and Southern Alps watersheds.
Two pot stills
The signature setup: a traditional direct wood-fired still (W), and a second-hand still relocated from the closed Karuizawa distillery (K). Blending the two streams in varying ratios is the structural idea behind the UNITED S series.
Karuizawa and Japanese craft history
Karuizawa Distillery operated 1955–2011. Closed-distillery bottles now command record auction prices. Part of its equipment was relocated to Shizuoka, meaning Karuizawa's stills are technically still in service today — a meaningful continuity in the history of Japanese craft whisky.
Domestic distribution exists but in small batches; many seasonal limited editions.
