The Krymchanin grape variety is a mid-season technical variety recommended for cultivation in the North Caucasus region. The vegetation period lasts about 128-138 days with a sum of active temperatures of about 2900°С. Bushes are vigorous or medium-sized, with large five-lobed leaves of medium lobing and a corrugated surface. Bunches are cylinder-conical in shape of medium density, weighing about 150-200 g; berries are small or medium-sized, round or oval, dark blue-black in color with a firm skin and juicy flesh. Berries contain 2-3 seeds, and must sugar content reaches 18-27%, with acidity of 8-11 g/dm³, providing a simple but pleasant taste. The variety is characterized by increased resistance to diseases such as downy mildew and powdery mildew, which allows reducing the number of sprays to one or two per season instead of the usual five to eight for less resistant varieties. Frost resistance reaches -24°C, ensuring its winter hardiness at a medium level. Krymchanin is capable of fruiting from replacement buds and does not require pollinators. Bush training is recommended as multi-armed, fan-shaped on a vertical trellis with pruning to 5-8 buds; load per bush is 40-50 buds and 25-30 shoots after shoot thinning. Planting area is 3.0x1.5 m with trunk training, suitable for non-sheltered zones. Krymchanin prefers fertile soils and southern slopes with good exposure, where it can be cultivated even on trunks. Yield is average, reaching 125-138 c/ha. Berries are used primarily for the production of red table and fortified wines, with a tasting score of about 7.8 points. The rootstock for the variety is often Cobber 5BB. Thanks to its characteristics and resistance, the Krymchanin variety is a reliable choice for viticulturists seeking high-quality technical grapes with good yield and resistance to unfavorable conditions.
