An object of the present invention is to provide a method for washing and immersing high-purity rice for brewing with high-purity rice, which is capable of washing high-purity rice R with fine bubble water W and absorbing an appropriate amount of water without lowering the raw material utilization rate. SOLUTION: In the method of washing and immersing high-polished rice R for sake brewing, the high-polished rice R for brewing is washed and absorbed with fine bubble water W containing fine bubbles in water. The highly polished rice R was housed in the container 3 through which the microbubble water W can pass, and the high-polished rice R was immersed in the microbubble water W for washing and water absorption while being stored in the container 3. [Selection] Figure 1【課題】原料利用率の低下を招くことなく、微細気泡水Ｗで高精白米Ｒを洗浄し適度な水分を吸水させることができる酒造用高精白米の洗米浸漬方法を提供すること。【解決手段】酒造用の高精白米Ｒを、水に微細気泡を含ませて成る微細気泡水Ｗで洗浄し吸水させる酒造用高精白米の洗米浸漬方法において、前記高精白米Ｒを、前記微細気泡水Ｗが透過可能な容器３内に収容し、前記容器３内に収容したまま前記高精白米Ｒを前記微細気泡水Ｗに浸して洗浄し吸水させるようにした。【選択図】図１
