The study of Shkoda grape of the new generation of selection of the National Research Center “Institute of Winegrowing and Winemaking named after V. E. Tairov” was conducted to identify the suitability of this sort to consume it fresh and use it in the winemaking.
The characteristics of Shkoda grape was given compared with wide district Karaburnu grape for table use in Odessa Region and sorts of a new selection grape – Arkadia, Flora, Muscat Pearl, Kardishakh. The mechanical analysis of the grape showed that Shkoda grape is a universal wine and table variety.
On the basis of the organoleptic estimation it is showed that Shkoda grape must be classified as the high-quality table variety of grape. Except for common factors (saccharinity and acidity) a number of indicators of chemical composition of Shkoda grape berry was identified as the additional quality criteria of table grape. It was established that the nutrition value of Shkoda grape is high.
The chemical composition and physical and chemical characteristics of the wort from Shkoda grape, considering biochemical characteristics of raw material and enzymatic action of the wort. The data analysis shows the possibility of preparation of wine materials from Shkoda grape as table and dessert. The organoleptical testing of red table dry wine material, prepared from Shkoda grape by fermentation of septum, showed that it is notable for the high organoleptic indicators. The dessert wine material received the low assessment because of the type mismatch.
