Edaoke (small branch tub)

Edaoke is a small vessel used in the sake brewing process. The term is derived mainly from oyaoke (the large vessel, or "parent tub"). Edaoke are used when sake is prepared in several small vessels rather than one large one, which makes it easier to control the temperature of the moromi (fermentation mash). Using edaoke allows temperatures to be evened out and the progress of fermentation to be adjusted more finely, which leads to better quality. In this way, edaoke play an important role in sake production.
