| Popis: | Modern development of the Russian viticultural and winemaking industry is aimed at the production of competitive varietal premium wines. It is premised on acceleration of the breeding process of domestic wine grape varieties with the preset course of processing. The purpose of this workск was to study the ratio between the most important quality components of the wines made from two classical and eight promising grape varieties domestic breeding (by Federal State Budget Scientific Institution “North Caucasian Federal Scientific Centre of Horticulture, Viticulture and Winemaking”, hereafter - Institute) to determine the unique varietal particular qualities. The experiment was performed in 2013–2018. The grapes were picked from two plots located in the Central zone and in the Taman subzone, Krasnodar region. The red varietal wines were made according to the same technology and observing the same processing modes. The analytical research was performed repeatedly with qualification assessment of the results. Two-way-ANOVA was used to identify the impact factors upon the wine components. As a result, the following appreciable grape varieties of the Institute’s breeding were isolated, which demonstrated high accumulation of phenolic substances (over 3,000 mg/l) and anthocyanins (700–1100 mg/l) in wine: Vladimir, Granatovy, Kurchansky, Dmitri; the grape varieties with high accumulation of trans-resveratrol in wine: Vladimir (4.7 mg/l), Dmitri (4.7 mg/l), and Kurchansky (3.0 mg/l); the grape varieties for which wine the mass concentration of malic acid was by 2 to 2.5 times higher than the content of tartaric acid: Vladimir and Dmitri. It was shown that Antaris variety has low ecological plasticity and wine of this variety could be differ qualitatively depending upon edaphoclimatic conditions of the subzone. |
