The method comprises the following steps: S1, preparing raw materials; s2, primary steaming: pouring the soaked raw materials into a steamer pot, spreading, flattening, steaming with big fire, and adding mung beans and pea meal; s3, re-steaming: adding warm water into the primarily steamed raw materials, steaming for 1-1.5 hours with soft fire, then stopping fire, continuously braising for 1-1.5 hours in the pot, and then taking out of the steamer. S4, quickly taking out of the steamer, adding Xiaoqu, uniformly stirring after adding the Xiaoqu, spreading for cooling, and putting into a cylinder for culturing bacteria and saccharifying for 12-36 hours; and S5, after saccharification, adding yeast for sealed fermentation, wherein the fermentation time is about 30-40 days. According to the brewing method of the grain wine fermented by seven grains, the solid state fermentation process of simultaneous cooking, simultaneous fermentation and simultaneous distillation is adopted, the production process of the grain wine is simplified, the pea meal is added to improve aroma and improve the fermentation effect of Xiaoqu, and the mung bean flour can reduce the damage of drinking to gastric mucosa.
