One of the main parameters of wine quality is crystalline stability, which is determined by the physical and chemical composition of wine. By the method of capillary electrophoresis 7 samples of wines produced in the wine-growing district of Sevastopol were analysed. It was shown that the mass concentration of potassium was in the range of 480-1181 mg/dm3, calcium - 58-132 mg/dm3. The sum of mass concentration of potassium and calcium in wines is 669-1313 mg/dm3; their ratio is 9-11.
