BIOCHEMICALANDORGANOLEPTICPROPERTIESOFWINESMADEFROMREDGRAPEVARIETIESBRED IN ARRIV&W
The aim of the work is to study the biochemical and organoleptic properties of red table wines obtained from grape varieties of interspecific 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 observed in the must from the Denisovsky and Augusta grapevine varieties. The highest content of extractive, phenolic and coloring substances was noted in the experimental wine from the Augusta variety. The content of phenolic and coloring substances in the studied sample from the Cabernet Severny variety was almost two times less than in the control Cabernet Sauvignon. According to organoleptic analysis, the highest tasting score was obtained from the Augusta grape variety (8.7 points)
