The aim of the research was to study the influence of the characteristics of new varieties and hybrids of Krasnostop Anapsky on the quality of grapes and technochemical parameters, and taste characteristics of wine products. The authors in the paper present research materials on must and dry wine materials from hybrid varieties and forms of crossed pairs of grapes (F/U "Dzhemete" × Krasnostop Anapsky) bred at the Anapa Zonal Experimental Station of Viticulture and Winemaking. All new grades and hybrid forms are of technical direction and average term of maturation. Productivity is high, tolerant to phylloxera. The must and wine material from the Krasnostop Anapsky variety was used as a control. The research was carried out in Anapa, Krasnodar Territo-ry, Anapa ampelographic collection. Formation of vineyards "Spiral cordon AZOS-1". The feeding area is 3.5×2.0 m. As a result of the analysis of the must from the studied varieties and hybrids, it was revealed that all the studied varieties and hybrids, with the exception of the 59-60 form, accumulated a sufficient amount of sugars to produce high-quality red wines – 19.9–22.9 g/100 cm3. The must of varieties Krasnostop AZOS, Kubanets and forms 59-24 had a concentration of phenolic compounds significantly higher than the control. The most optimal in terms of glu-coacidometric index was the wort of the con-trol variety Krasnostop Anapsky and forms 59-49 and 59-24. The wine materials of most of the studied varieties and hybrids were not inferior to the control in terms of alcohol concentration. The largest amount of phenolic substances was found in experimental wine materials from grapevine varieties Krasnostop AZOS, Kubanets and hybrid form 59-24. In the studied wine materials, the largest amount of substances of the anthocyanin group was found in samples from the Krasnostop AZOS grapevine variety and in hybrids 59-24 and 59-60. According to the results of the tasting analysis of wine materials from the studied varieties and hybrids, it was revealed that they are superior or not inferior in organoleptic parameters to the control classic variety Krasnostop Anapsky.
