The invention provides a brewing method of mulberry wine with low alcohol concentration. The brewing method of the mulberry wine with low alcohol concentration comprises the following steps: (1) selecting raw materials; (2) carrying out squeezing and crushing; (3) carrying out treatment with pectinase; (4) carrying out fermentation, and terminating the fermentation by adding a yeast inhibitor, namely cinnamic acid or potassium cinnamate, at a dosage of 200-880 mg/L or adding the yeast inhibitor in coordination with SO(2); (5) carrying out separating and squeezing; (6) adding gel so as to be subjected to clarification; (7) carrying out freezing; and (8) obtaining a finished product. The brewing method of the mulberry wine with low alcohol concentration is scientific, rational, simple in steps, and easily controllable in conditions. Moreover, a fermentation inhibition technology combining the cinnamic acid or the potassium cinnamate with low temperature is creatively adopted; and fresh mulberry fruits, rather than mulberry fruit concentration, are used without water, so that fermentation is carried out by adopting pure mulberry juice, thereby preserving nutrients, fruit aroma and taste of the mulberry fruits to a maximum extent. In addition, alcohol fermentation is carried out by completely using sugar in the mature mulberry fruits without addition of artificial sugar. The mulberry wine with low alcohol concentration brewed by the method has an alcohol concentration of 1-7% (v/v) and a total acid concentration of 4-10 g/L, and is brighly ruby in color, clear, transparent, free of suspension, free of precipitate, sour-sweet and palatable in taste, mellow in wine texture and suitable for various of populations, including the men, the women, the elderly and the children, todrink.
