Severny is a technical grape variety bred in 1947 at the Y.I. Potapenko All-Russian Grape and Wine Research Institute by pollinating the Severny variety with a mixture of pollen from Muscat of Alexandria, Muscat Blanc, and Muscat de Hongrie. This variety belongs to wine varieties with medium ripening; technical berry ripeness occurs in early September, and the harvest is usually conducted from late September to mid-October. Bunches have medium size, cylinder-cone shape, and medium density; berries are round, white, and medium-sized. Bushes are medium-sized, vigorous in youth, with one-year-old canes that mature to 52.7-73.8%.
Severny is distinguished by enhanced resistance to diseases and frosts, making it particularly valuable for cultivation in the southern zone of covered viticulture. Frost hardiness allows preserving up to 61.9% of healthy buds at temperatures down to -23°C, and up to -26°C on the soil surface. Berry infection by downy mildew reaches no more than 10%, and by gray rot—up to 20%. Sugar content in berry juice varies from 16.7 to 22%, acidity from 8 to 11.3 g/l, ensuring high-quality raw material for winemaking.
The variety is recommended for producing various types of wines—white table, dessert, strong, and sparkling—as well as for making juices and cognacs. Training bushes in the form of a high-stem double-arm cordone with drooping one-year-old growth allows obtaining high yields with minimal labor and material costs. However, the variety is prone to overloading with fruit, so strict control of bud loading is necessary to maintain quality and yield stability.
