TECHNOLOGICAL ASSESSMENT OF NATIVE RED DON ABORIGINE GRAPEVINE VARIETIES
The results of technological evaluation of red Don native wine varieties of grapevine grown on ampelographic collection of the Institute are presented: Krasnostop zolotovskiy, Varuskin, Zemledar, Stariy Gorun, Syphon Cherniy. These varieties were used to make natural table wine samples according to the classical technology. The research was carried out in the laboratory of winemaking technology in micro-wine production. The mass of one batch of grapes was 5-10 kg. The main physical and chemical indicators of grapes, as well as giuco-acidometric index and an indicator of technical maturity, were determined. In the prepared wine samples, the main chemical parameters were determined, and an organoleptic assessment was performed. As a control variety, Krasnostop zolotovsky was taken, which is included in the State register of varieties approved for use in the Russian Federation. Reresults of three years of testing the conclusions about the feasibility of using varieties: Varuskin, Zemledar, Stariy Gorun, Syphun Cherniy for the expansion of production of wine with geographical status.
