Evaluation of must and wine from hybrids of Krasnostop Anapskiy varieties

The experiment studied the influence of the characteristics of new varieties and hybrids based on Anapa Krasnostop on the quality of grapes, technochemical parameters and taste characteristics of wine products. The paper presents research materials on must and dry wine materials from varieties and hybrids of grapes obtained by crossing F/U Dzhemete and Krasnostop Anapa by breeders of the Anapa Zonal Experimental Station of Viticulture and Winemaking. All new hybrid varieties are intended for technical processing. Grapes of medium and late ripening, high yield, relatively resistant to phylloxera. The Krasnostop Anapa variety, must and wine material from it were selected as control. Place of laying the experience of Anapa, Krasnodar Region, Anapa ampelographic collection. The vineyard is formed according to the type of spiral cordon AZOS-1. The planting scheme is 3.5 x 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 the amount of sugars sufficient to produce high-quality red wines - 19.9 -22.9 g/100 cm3. The must of the varieties Krasnostop AZOS, Kubanets and forms 59-24 had a significantly higher concentration of phenolic compounds than the control. The most optimal in terms of glucoacidometric index was the must of the control variety Krasnostop Anapa 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 highest concentration of substances of the polyphenol group was found in wines from the hybrid 59-24 and from the Krasnostop AZOS and Kubanets varieties. Coloring anthocyanin substances in the highest concentration were found in the studied wine materials from hybrid grapes 59-24 and 59-60, as well as the Krasnostop AZOS variety. The tasting analysis showed that the wines from the studied hybrids and varieties are not inferior or superior in organoleptic parameters to the control classic variety Krasnostop Anapa.
