Doburoku, a traditional sake with a history older than that of Japanese sake.

Doburoku is a traditional alcoholic drink with a longer history than sake. Made from rice, koji, water, and yeast, it has a cloudy appearance due to the rice grains and yeast remaining in the liquid. It has a sweet, fresh flavor. While it was once made at home, homemade production is now prohibited, and commercial production is limited. Doburoku dates back to ancient times and has a much older history than sake (nihonshu), which developed later.
