Hot mountain spring water creates a unique mash for fermentation.


From Grain to Glass
Our meticulous malting process begins with soaking and sprouting barley for three weeks, followed by careful drying and heating. This essential step enhances the flavor profile, setting the foundation for our exceptional whiskies.
The Art of Mashing with Pure Mountain Spring Water
At the heart of our process lies the careful mashing of cooked grains and malted barley with pristine mountain spring water from Nagano. This vital step creates a rich liquid known as mash, setting the stage for the unique flavors that define our whisky.


The Art of Fermentation
Fermentation at higher altitudes creates a unique environment that enhances the aroma extraction from barley. This meticulous process contributes to the distinct flavor profile of our whisky.
Bottling Process for Optimal Flavor Retention
Our whiskey is carefully bottled in non-reactive glass to ensure that its rich flavors are preserved. This meticulous attention to detail guarantees that every sip reflects our commitment to quality.
