Autumn Black is a table grape variety of medium or medium-late ripening period, known for its high yield and good marketability. The bushes of this variety are vigorous with hermaphroditic flowers, which contributes to stable fruiting. The vine is characterized by increased growth rate, and an average of 1.3-1.5 inflorescences form on one shoot. The clusters are conical, medium density, weighing from 500 to 1500 grams, which makes them convenient for harvesting and transport.
The berries of the Autumn Black variety are large and very large, elongated or inversely egg-shaped, with dark blue skin covered with a waxy bloom. The weight of one berry is 6-7 grams. The pulp is fleshy, acid-sweet, with a sugar content of 16-18% and acidity of 7-8 g/l, which ensures a pleasant and balanced taste. Harvest maturity occurs in the second decade of September, which allows using this variety for late consumption.
Frost resistance of Autumn Black is medium or slightly increased; the variety can withstand temperatures down to -24...-25°C. However, with sharp fluctuations in soil moisture, the berries are prone to cracking and gray rot, so it is important to maintain regular soil moisture. Undamaged berries store well in the refrigerator for more than two months, which makes this variety convenient for long-term storage and transport.
