Tsuiki Copperware Sake Cup Blue

A life-long sake container which makes the sake becomes mellow. All containers are hand-made by craftesmen with hammers from a single copper plate.

■How the containers affect the taste of sake?
The bactericidal action of copper purifies the water in sake, which would eliminate the off-flavor of sake.
Especially for the dry sakes such as Special Junmai and Honjoz, the change in tastes would be even more significant.

■Special features
As the name implies, all containers are man-made products by striking a single copper plate to corresponding shapes and the roughness of the surface is the proof of this technique. This know-how is so difficult that each craftsman needs 4-year experience to become a maker of the container. This traditional technology is developed by the living national treasure Mr. NorioTamagawa and Mr. Itami Shimakura.
