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.
