Great news for fans for Chichibu whisky: Chichibu’s second distillery is now producing more Chichibu for the world! Recently, Daniel, a friend of mine, visited Chichibu in January of 2020 and spoke with Yumi about Chichibu 2!
The unique feature of Chichibu
Each washback contains 10kg of yeast which undergoes fermentation for 4 days, compared to an industry standard of 48 hours. This longer fermentation time allows for slower lactic acid bacteria fermentation that contributes to the character of Chichibu’s new-make spirit. The cut of the heart of the distillate is also not just determined by measurements, but a human nose to ensure that the new-make spirit smells clean!
What about Chichibu 2?
In Chichibu 2, the washbacks are wooden as well but made of European oak instead of Mizunara oak. Unlike Chichibu 1, Chichibu 2 has directly heated stills which could possibly produce a new-make spirit that is more robust and complex. I mean, there has to be a reason why Glenfarclas stuck with direct heating even after trying steam coil distillation. Chichibu 2 will use the same yeast as the original distillery but the fermentation time in Chichibu 2 is slightly longer.
Unfortunately, at the time of this article (March 2019), Yumi cannot answer how different the two Chichibu new-make spirit tastes. Production and testing started in October 2019, so adjustments may still be ongoing, and data might need processing.
One thing is sure, Chichibu 2 will produce 5 times the capacity of Chichibu 1! Currently, Chichibu 1 stands at a capacity of 60 000 – 90 000L of Pure Alcohol annually. That will mean more Chichibu to go around… in about three or more years.
More about Chichibu
Chichibu sources spring water from the nearby Arakawa (荒川) river. The water is clean and soft, suitable for fermentation and dilution.
Chichibu distillery is currently using barley from various sources. 70% is from Crisp malts in the UK, 20% is from Europe, and 10% is local Japanese barley! The grist ratio is at an industry standard of 70% grist, 20% husks and 10% flour.
The peated expressions of Chichibu currently use peat that comes from northeastern Scotland, in between the Highlands and Speyside.
Casks in Chichibu
The team at Chichibu also creates a unique Chibidaru cask. The Chibidaru is comprised of Mizunara cask ends (the circle) with American white oak staves.
Mizunara (above) is somewhat porous and loses whisky quick. But this innovation minimises leakage and while still providing Mizunara flavours. Chibidaru casks are also smaller than the standard bourbon barrel. This small 130-litre cask offers a greater surface area to volume ratio than the standard barrel. Due to its smaller size, these Chibidaru casks rest atop of the casks in the warehouse. This position exposes the cask to a slightly higher internal temperature with more temperature fluctuation due to its smaller size. *flashbacks of heat transfer lectures* The combination of small cask size, higher average internal temperature and increased variation allows Chibidaru casks to mature whisky faster.
In most stacks of casks, the wee Chibidaru casks will be on top with 2 rows of 200L bourbon barrels below it, and the bigger 480L sherry butts at the bottom. Chichibu is also very experimental with the casks they use.

There was even an ex-tequila cask spotted in the warehouse! Unfortunately, that cask that I spotted 3 years ago is still maturing.
The near future of Chichibu
As mentioned earlier, Chichibu is using local barley, and Chichibu local barley might take a while to reach markets. Although the distillery intends to use more local barley, it is improbable that the distillery can move to use 100% local Japanese barley, especially with their plans of increased production.
Talks are underway to use local peat sourced from a company that is approximately 1km away from Chichibu distillery. Imported peat will still be the primary source for the foreseeable future.
The team at Chichibu hopes that the new distillery will push increase production. This would alleviate pressure off the first distillery, which can start doing unique experimental craft whisky. But look out, there may be a plan to do direct retail in the future if production allows!
