“…The mass concentration of phenolic and coloring substances in the clones of Cabernet-Sauvignon, Merlot and Bastardo Magarachsky exceeded those of traditional varieties. In general, the value of these indicators of all studied wine materials corresponded to the values typical for the Western European ecological-geographical group [5][6][7][8][9][10][11][12][13][14][15]. Tasting assessments of the studied wine materials are presented in Figure 1.…”

The research has shown that clones of the Cabernet Sauvignon variety R-5 and R-8 are distinguished by higher rates of fruiting. The average bunch weight in clones reaches 188.7 ± 0.02 g (R-5) and 177.3 ± 2.6 g (R-8), exceeding the control. The yield per bush is on average 5.34 ± 0.21 kg and 4.25 ± 0.07 kg, exceeding the control by 1.54 - 1.23 times. Shoot productivity in terms of bunch wet weight in the Cabernet-Sauvignon R-5 clone is characterized as “high”. The clone of the Merlot R-3 variety has a high fruiting coefficient and a high fertility coefficient. The bunch weight of the clone reaches an average of 227.6 ± 4.3 g, the yield per bush is 6.3 ± 0.1 kg, exceeding the control. Shoot productivity in terms of bunch wet weight in the Merlot R-3 clone is characterized as “very high", in the control it is “high”. The clone of the variety Bastardo Magarachsky VCR-1 has a higher fruiting coefficient than in the control. The average weight of a bunch of a clone reaches 247.7 ± 1.4 g and exceeds the control (186.3 ± 9.14 g). The yield per bush is within 4.62 ± 0.2 kg, exceeding the standard variety by 0.85 kg. Shoot productivity in terms of bunch wet weight in Bastardo Magarachsky VCR-1 clone is characterized as “very high", in control this indicator is defined as “high”. The degree of variability of most traits in populations of standard varieties is characterized as average, which indicates the heterogeneity of the population and the possibility of further identification of new biotypes. According to the technological assessment, the indicators of wine materials in terms of physicochemical and organoleptic indicators, the introduced clones of the studied varieties were superior to the control varieties. In terms of the volume fraction of ethyl alcohol, mass concentration of volatile and titratable acids, all wine materials met the requirements of regulatory documents. Tasting scores of Cabernet Sauvignon wine materials were 7.7-7.9 points. The highest marks were obtained for the sample generated from clone R-8. Wine materials produced from the Merlot variety were noted as high quality, with pronounced varietal characteristics.

“…The main anthocyanins of Vitis vinifera grapes are monoglycosides of malvidin (more than 50%), peonidine, dolphinidin, petunidin, in a smaller amount -cyanidin and acylated monoglycosides of peonidine and maldivine [1][2][3][4][5][6].…”

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.
