The variety belongs to the Black Sea ecological-geographical group. The growing season is about 170 days; ripening occurs at the end of September or the beginning of October. The vines are characterized by medium to high vigor and have large, five-lobed, wrinkled leaves with dense, rust-colored pubescence on the underside.
The variety has high fertility; however, excessive load on the vine leads to a decrease in the sugar content and extractability of the crop. Gamza tolerates drought well but is sensitive to winter cold and gray mold. The purpose of the variety is exclusively for processing — the production of red table and dessert wines.
