Abstract
An important direction of the long-term plan for the development of viticulture and wine-making in the Crimea is the production of products with a geographical status. One of the signs that determine the origin of wines is their mineral composition, which depends on soil and climatic conditions and agrotechnical methods of cultivation. The aim of the study was to use the ratios of mass concentrations of potassium, sodium, calcium, magnesium cati-ons to assess the geographical position of wines made from grapevine varieties growing in different regions of the Crimea and Ukraine. A comparative analysis of the ratios of К+/Na+, K+/Ca2+, K+/Mg2+, Ca2+/Mg2+ cati-ons and tartaric acid to the sum of cations was carried out. A significant difference in the mass concentration of the sodium cation and К+/Na+ ratios in these regions has been estab-lished. The ranges of ratio of К+/Na+ cations for some Crimean enterprises have been speci-fied.
