The research work presents the results of studies of the composition of anthocyanins, monomeric forms of phenolic substances, oligomeric procyanidins, polymer forms of phenolic substances in wine materials Cabernet Sauvignon, Merlot, Syrah, Petit Verdot, Sangiovese, Marcelan obtained from grapes growing in the Crimea. It was found that the main coloring material in the wine materials under study was malvidin-3-O-glycoside. The proportion of this compound ranged from 42.9% to 54.3% in the total of all anthocyanins. The highest mass concentrations of oxybenzoic and hydroxycinnamic acids are determined in the wine material Marcelan. In the Sangiovese wine material, the highest concentrations of flavan-3-ols are determined. Mass concentrations of quercetin-3-O-glucoside in the test samples were 4-17 mg/dm3; quercetin - 1-7 mg/dm3. Mass concentrations of oligomeric procyanidins were in the range of 106-240 mg/dm3 and the highest value was determined in the wine material Marcelan, the lowest Cabernet Sauvignon. Mass concentrations of polymer forms of phenolic substances amounted to 1487-2998 mg/dm3.
