YANYKH ZERVA

Yanykh Zerva is a Crimean grape variety belonging to the Eastern ecogeographical group. It is a mid-late ripening variety, reaching maturity in the middle or third decade of September. Bushes have medium or high vigor, and their medium height allows for successful cultivation in Crimean conditions. Leaves are of medium size, asymmetrical, predominantly three-lobed, less frequently five-lobed, weakly dissected, with a grooved blade and edges curved downwards or funnel-shaped. Flowers are hermaphroditic, which promotes good pollination. Bunches are medium-sized, cylindrical, sometimes branched and loose, weighing about 290-310 grams. Berries are of medium size, elongated, asymmetrical, with a thin edible black skin with a dark purple or blue-black tint, covered with a dense waxy bloom. The flesh is crisp, fleshy, with a harmonious taste, and the juice is colorless. Berries contain 15 to 20 g of sugars per 100 cm³ and titratable acids within 5-8.5 g/dm³, providing a balanced taste and making the variety suitable for both fresh consumption and the production of table and dessert wines. The variety is characterized by medium yield, about 75 centners per hectare, and medium susceptibility to fungal diseases such as mildew, oidium, and gray mold. It has good winter hardiness, withstanding temperatures down to -21°C, and is also resistant to periodic droughts. Despite the fact that the variety is not widely distributed and currently occurs mainly in collections, it is of interest due to its taste qualities and adaptation to the climatic conditions of Crimea.
