The circulating flow of mash in a deep fermentor for sake brewing was investigated by measuring the floating rate of clustered rice in the fermentor (8.0m×3.3mΦ).1) The circularing flow of mash was caused by the flotation of clustered rice due to the buoyancy of CO_2 gas produced in the sedimented zone of rice particles.2) The flotation occurred intermittently and continuously playing an important role in mixing the mash in the industrial large-scale fermentor.3) The floating mash which rose along the inside wall of the fermentor was rectangular in shape, and mostly about 30 cm in length and 20 to 30 cm in width. The minimum and maximum fluxes were 8.3 and 11.8g/cm^2・min(av. 10.1).The floatin mash near the center of fermentor was most frequently circulating, about 30 cm in diameter, and its minimum and maximum fluxes were 26.3 and 118.7 g/m^2・min(av. 56.2).
