A unique offering which has been fermented in a traditional wooden sake tank. This lends vanilla and cedar notes, on top of straw and fragrant mushrooms. A slight pleasant astringency can be found on the palette, and the flavors are gentle and calming.
This sake has a very strong cult-appeal in Japan. Imayotsukasa revived the process of fermenting sake in wooden barrels in 2010. It was often sold out due to small production. In recent years, they have raised money through crowd funding to purchase 2 new large wooden barrels to brew this sake in.
