BIOCHEMICALANDORGANOLEPTICPROPERTIESOFWINESMADEFROM-REDGRAPEVARIETIESBRED IN ARRIV&W

Abstract

The aim of the work is to study the biochemi-cal and organoleptic properties of red table wines obtained from grape varieties of inter-specific origin growing in the vineyards of the Novocherkassk branch of the experimental field of ARRIV&W. The research was carried out on red grape varieties of interspecific origin Denisovskiy, Cabernet severniy, Avgusta. After the research, the following results were obtained. The largest stock of phenolic and nitrogenous substances was ob-served in the must from the Denisovsky and Augusta grapevine varieties. The highest con-tent of extractive, phenolic and coloring sub-stances was noted in the experimental wine from the Augusta variety. The content of phenolic and coloring substances in the stud-ied sample from the Cabernet Severny variety was almost two times less than in the control Cabernet Sauvignon. According to organolep-tic analysis, the highest tasting score was ob-tained from the Augusta grape variety (8.7 points)
