PURPOSE:To obtain SAKE (rice wine) or such by automatic control in good productivity, by pretreating polished rice with an enzyme agent containing protease and amylase at <= a specific temperature, sterilizing the treated material of polished rice under boiling, liquefying the sterilized material with amylase and subjecting the liquefied material to alcohol fermentation. CONSTITUTION:A fermentation device 3 equipped with a raw material feed opening 5 at the top, a product output 17 at the bottom, a heating and cooling jacket 8 at the outside and a stirrer 1 in the interior is prepared. Then washed raw material rice is fed from the raw material feed opening 5 to the fermentation device 3, further water is added, fully absorbed in the rice, an enzyme agent containing protease and amylase is added to the device and the rice is treated at <=65 deg.C. Then, the treated material of the rice is sterilized under heating, cooled to about 65 deg.C and saccharified with amylase. Then the saccharified material is cooled to about 25-26 deg.C and subjected to alcohol fermentation with yeast to give the aimed SAKE.
