The invention relates to a method for making a frozen dough through fermented-rice wine. The method comprises the following steps that 1, flour and water are mixed for sour dough fermentation, and a fermented dough is obtained; 2, the fermented dough and dietary alkali are mixed to be uniform, and a first dough is obtained; 3, activated yeast is added into the first dough, a modifying agent is added, the mixture is mixed to be uniform, and a second dough is obtained; 4, flour for secondary butt connection is added into the second dough obtained in the step 3, stirring is carried out, and a third dough is obtained; 5, the third dough is divided into blocks, rolled to be round and reshaped; 6, the rolled and reshaped dough is fermented, and the fermented dough is obtained; 7, the fermented dough is frozen at the temperature of -80--120 DEG C for 10-20 min, the center of the dough is at the temperature of -10--15 DEG C, and the frozen dough is obtained. The frozen dough prepared through the method has the advantages of being convenient to convey and store before being steamed and being free of crack and good in taste after being steamed.
