Abstract
The study of ionic composition of wines prepared from grapes grown in 5 viticultural and winemaking regions of Crimea was carried out. The mass concentration of chloride anions was determined by the potentiometric method; cations of potassium, calcium, magnesium, sodium - by capillary electrophoresis; excess sodium - by calculation method. A total of 50 white and 40 red wines were studied. Preliminary variation ranges of the studied indicators were established for samples from each area, and their average values were determined. It was shown that the content of excess sodium in the samples does not exceed the regulated by OIV value of 80 mg/l. The research results will replenish the data bank created to characterize the geographical origin of Crimean wine products, and will be used in the development of elements in the identification system for wines with geographical status.
