FIELD: wine industry. SUBSTANCE: method involves preparing ammonium salt of melanin, pH 6-7. 100-200 mg/l of resulting solution is added to wine and mixed. Then wine is saturated with oxygen for 10-40 min. The flow rate of oxygen is based on W = C V/t submitted in the description of the invention. After saturation with oxygen, wine is seasoned for 12-16 h. Resulting sediment is filtered off. EFFECT: higher efficiency. 1 tbl
