Abstract
The paper presents the results of technological evaluation of red wine varieties breeded by All-Russian Research Institute for Viticulture and Winemaking: Vesta, Cherny, Zhemchug, Au-gusta, Teremnoy, Mugofir. These varieties are characterized by high sugar accumulation. Li-queur wines were prepared using classical tech-nology. The research was conducted in the la-boratory of wine technology in micro-wine production. The weight of one batch of grapes was 10–25 kg. The main physical and chemical parameters of wort and wine were determined. Wine distillate was used as an alcoholic agent. For maintaining and enhancing the varietal aroma of grapes we used technology of frac-tional alcoholization. With the help of degusta-tions, organoleptic characteristics of the ob-tained samples of liqueur wines were carried out, as a result of which preliminary conclusions were made about the feasibility of using the studied varieties for the preparation of red li-queur wines. All the studied grape varieties can be recommended for the production of liqueur wines, pink and red.
