This article presents the results of studies of wines obtained from Chardonnay, Sauvignon Blanc, Riesling, Pinot Noir, Cabernet Sauvignon grapes grown in the Krasnodar Region in 2012-2016, in the territory of the �Semigorye� geographical object (Novorossiysk). The peculiarities of the mineral composition of wines, in particular inorganic cations (ammonium, potassium, sodium, magnesium, calcium), in the wines produced by the wine company � Imenie �Sikory� LLC, are revealed, depending on the grape variety and crop year. Joint correlation dependencies are established. Inorganic cations were determined by the method developed in the Scientific Center �Wine-making� FSBSI NCFSCHWV. It is established a higher mass concentration of potassium in Chardonnay and Sauvignon Blanc wines, compared with Riesling, indicating a higher photosynthesis productivity and intensive vegetation of grape plants of these varieties. The minimum, maximum and average mass concentrations of inorganic cations reveal the the peculiarities of the �Imenie �Sikory� LLC, caused by the natural conditions characteristic of the Semigorye geographical object. The results of the analysis show the correlation between the content of elements K-Na, K-Mg, Na-Mg. The correlation between elemental content and grape variety is significant for K, Na and Mg. The total concentrations of inorganic cations ranged from 354 to 1387.6 mg / dm3 and from 905 to 1682.9 in white and red wines, respectively. The results of this scientific work can be the basis for the development of a modern system for assessing the quality and authenticity of wine products in the Russian Federation, as well as be used for regional identification of wines of various origins.
