Tsunan Sake Brewery Participates as a Drink Partner at 'Sustainable Food Night #28'
Tsunan Sake Brewery Co., Ltd. (Head Office: Tsunan-machi, Nakauonuma-gun, Niigata Prefecture; CEO: Kengo Suzuki, hereinafter 'our company'), a sake brewery based in Tsunan, Niigata, participated as a drink partner at Sustainable Food Night #28, held on Monday, July 28, 2025, at the Sustainable Food Museum in Nishi-Shimbashi, Tokyo.
This event's theme was 'The Aroma of Cacao Crafted through Fermentation – The Development of Chocolate in Southeast Asia and Japan.' The guest speaker, Mr. Akira Fukumura, CEO of WHOSE CACAO, shared insights in a talk session about fermentation and product development for specialty cacao, covering local fermentation techniques in Southeast Asia and their applications in the Japanese market.
As the drink partner, we presented our 'GO GRANDCLASS Uonuma Koshihikari Edition,' representing our role as a bearer of Japan's sake fermentation culture. This sake, embodying the terroir of the snowy Tsunan region, was introduced to participants, highlighting its naturally fermented and aged flavor profile without the use of artificial flavors or additives. The similarities in fermentation processes between sake and cacao sparked significant interest among attendees.
The event also featured aroma comparisons of cacao beans from different origins, fermented cacao cola by WHOSE CACAO, and tastings of various chocolates, allowing visitors to experience the diverse aromas and flavors created through fermentation.
Tsunan Sake Brewery will continue to contribute to the development of a sustainable food culture centered on fermentation and to explore the untapped potential of Japanese sake.
