Shizuoka Distillery marks 10th anniversary by selling whole casks of aged whisky

10th anniversary “Shizuoka Private Cask Archive”

Gaiaflow Shizuoka Distillery is a craft whisky distillery in the hills of Shizuoka, the prefectural capital of Shizuoka Prefecture. To coincide with the tenth anniversary of receiving its whisky production licence on 28 September 2026, it launched a commemorative scheme, the “Shizuoka Private Cask Archive”, on 19 September. Ten types of whisky aged for 6 to 9 years have been made available, and the idea is that buyers purchase an entire cask rather than a single bottle. Prices range from 2.99 million yen to 7.77 million yen including tax. Each of the ten products is limited to a single cask, and they were sold on a first-come, first-served basis through the distillery’s online shop.

Comparing samples to choose “your own cask”

What makes this scheme interesting is the way the cask is chosen. Once a purchase is confirmed, three to five samples of the chosen type are sent to the buyer. Even when the maturation period, still, malt and cask type are the same, each cask has its own aroma and flavour. Buyers compare the samples and decide for themselves which cask will actually be bottled. The alcohol strength and the wording on the label can also be chosen to suit the buyer’s wishes, and the entire contents of the cask, which exceeds 100 litres, are delivered as bottles with an original label. The line-up includes whisky matured in casks previously used for American bourbon (bourbon barrels), as well as in wine casks and sherry casks (sherry butts), and a rare whisky made with Golden Promise, a traditional Scottish barley variety. Please note that, once payment has been made, buyers cannot cancel for their own reasons.

The wood-fired still “W” and “K” from Karuizawa

The character of Shizuoka Distillery’s whisky rests on two stills: “W”, its own still directly heated by a wood fire, and “K”, which was moved from the closed former Karuizawa Distillery. A variety of malts is also used, including Japanese-grown barley, and the ten types in this scheme read like an “archive” tracing the distillery’s work over the past decade.

For European readers, buying a whole cask may not be realistic. Even so, the scheme sums up the thinking behind Shizuoka Distillery well: even when the conditions are matched, the flavour changes from cask to cask. If you come across a Shizuoka Distillery bottle in a European specialist shop, check the still named on the label (W or K), the origin of the malt and the cask type. By tasting two bottles with similar specifications side by side, you may be able to experience at home the “differences from cask to cask” that the distillery wants to convey with this scheme. The announcement does not make clear whether purchases can be made from overseas.
