Ikawa: Making Whisky Close to the Sky

At 1,200 metres above sea level, Ikawa is an unusual place to make whisky. The distillery sits in the forests of Shizuoka’s Southern Alps, where mountain spring water, changing temperatures and the surrounding woodland all played a part in the decision to build.

How do you manage fermentation through cold winters? What does lower atmospheric pressure mean for still design? And what happens when the forest around a distillery can also provide wood for its casks? At Ikawa, these questions are part of the work of making whisky.

At Casa de Vinos, we work directly with Ikawa as its exclusive Australian importer. With Flora 2025 and Flora 2026 the focus of our latest selection, alongside Fauna 2025, it is a good moment to look more closely at the producer behind the bottles.

A distillery built around its surroundings

Ikawa opened in November 2020. Its producer, Juzan, identifies three reasons for the location: the maturation environment, the local spring water and the forest’s timber resources.

The distillery uses malt from Scotland. That is a useful detail in a conversation about Japanese whisky: a strong connection to place does not mean every ingredient comes from the immediate surroundings. At Ikawa, that connection includes the water, the woodland and the decisions made during production.

What changes when you make whisky in the mountains?

The distillery reports temperatures ranging from around 30°C in summer to minus 15°C in winter. Its stainless-steel fermentation vessels have heating and cooling jackets, allowing the team to manage fermentation as conditions change.

Ikawa also says that lower atmospheric pressure informed its choice of straight-necked pot stills with slightly downward-sloping lyne arms.

These details tell us more than simply describing the whisky as “high altitude”. The location presents conditions that the team responds to through equipment and working decisions. It does not give us a shortcut to predicting the flavour of every bottle.

From the forest to the cask

Alongside bourbon and sherry casks, Ikawa has made casks using Mizunara from its own forest. Its first local Mizunara cask was made from a fallen tree.

That is a particularly interesting connection between the distillery and its surroundings. It is also worth being precise about what it means when choosing a bottle: the use of local Mizunara at the distillery does not establish that every release contains whisky matured in it.

For any individual expression, look at the stated cask composition. Full maturation, a finishing period and the inclusion of a Mizunara-matured component are different things.

Getting to know Ikawa through Flora and Fauna

Ikawa’s Dessin Series offers two starting points: Flora explores unpeated single malt, while Fauna introduces the distillery’s peated spirit. Our selection brings together Flora 2025, Flora 2026 and Fauna 2025.

Flora 2025 and Flora 2026 give us the opportunity to compare two releases from the same series. Start with the aromas before comparing texture, fruit, oak and the finish. Which appeals more to you? Does your preference change with a little water or after a few minutes in the glass?

Check each release’s cask details and strength alongside its tasting notes. The year in the name is not an age statement, and the later edition should be approached as an individual whisky rather than assumed to be the older or better one.

For drinkers interested in smoke, Fauna 2025 offers another way to get to know Ikawa. Tasting across Flora and Fauna gives you a broader introduction to the distillery than a single bottle can.

You can browse the Ikawa releases at Casa de Vinos for individual bottle information and current availability, or ask us for help choosing between them.
