Description
Vostorg ('Delight') is a very early white grape from the Potapenko institute in Novocherkassk, Russia, bred by Ya. I. Potapenko, I. A. Kostrikin and A. S. Skripnikova and listed in the state register since 1992. Large bunches carry round to oval-round white berries of about 5 to 6 g with crisp flesh and a harmonious taste, and sugar can reach 26 percent. Ripe grapes hang well on the vine for weeks.
Characteristics
White table grape, also registered for wine; very early, around the first ten days of August at Novocherkassk (114 days); large conical bunches (336 g in institute trials, 500–700 g in the register); round to oval-round 5–6 g berries; crisp flesh; about 2 seeds; hardy to −25/−26 °C; good resistance to downy mildew and grey rot; no resistance to powdery mildew or phylloxera
Growing Tips
Vostorg is winter-hardy and grown uncovered around Rostov, where it withstands about −25 to −26 °C. It has good resistance to downy mildew and grey rot but is not resistant to powdery mildew, so spray for that. It is also not phylloxera-resistant; the institute recommends grafting onto Kober 5BB. Ripe bunches can hang 30 to 45 days.
