Annotation

In the article it is noted that cultivation and introduction in the production of the Don native grapes varieties in the territory of Krasnodar Region will give the chance to make from them the high-quality and unique wines, and also will provide the increase in interest of producers in vine growing and wine-making branch. The objects of our research the wine materials from the following grapes varieties have been used: Bessergenevsky No. 7, Sibirkovy, Varyushkin, Granatovy, Muscat Hamburg. Processing of grapes raw for receiving of wine materials was carried out in 2015 in the shop of micro wine-making of the North Caucasian Regional Research Institute of Horticulture and Vitisculture. During the research the analyses of the physical and the chemical composition of the wine materials prepared from above-mentioned grapes varieties have been carried out using the method of a capillary electrophoresis in the laboratory of "Wine-making" Center a nd in the Center of collective use of NCRRIH&V with use of Capel-105 device. When the analyses are carrying out the standard techniques, and also the techniques developed by employees of NCRRIH&V were applied. The con-tent of organic acids and cations of metals in the samples from the studied grapes varieties is determined. The carried out analysis has shown that the greatest quantity of wine acid contains in the samples from grapes of Bessergenevsky No. 7. As a result of study of cationic composition of wine materials it is revealed that the researched samples have the high content of potassium (528,3-1811 mg/dm3) that is coordinated with literary information. All samples presented in a research have a harmonious taste, they have also the positive reviews and the high tasting assessment of experts-tasters of NCRRIH&V. It gives the grounds to recommend the grapes varieties studied by us for production of qualitative wine materials and wines.
