Sheegene-20
ActiveVitis vinifera L. · Common grape vine

The vine has high growth vigor. Leaves are medium to large in size, five-lobed, with varying degrees of lobing. Clusters are large, cylindrical to cylindrical-pyramidal, often winged, ranging from medium-dense to very dense. Berries are medium to large in size, round, yellowish-green in color with a thick skin.
The variety is very late, with harvesting in Italy taking place in October. It demonstrates high and stable yields, as well as good adaptation to heat and cold winters. It possesses resistance to downy mildew and powdery mildew, however, due to the dense cluster, it is prone to grey mold in rainy weather.
The purpose of the variety is universal: it is used for the production of still dry, sweet, and sparkling wines, as well as a table grape. Wines are characterized by a straw-yellow color, pronounced acidity, and aromas of herbs, citrus, apricot, and dried fruits.
