Matyas Janos — a table grape variety developed in Hungary by hybridizing the 'Shasla Fioletovaya' and 'Muscat Ottonel' varieties. This variety is characterized by its early-to-medium ripening period and high yield, reaching 150–200 centners per hectare. The vines have medium vigor, and young shoots are distinguished by a vinous-red bark with strong web-like pubescence. Leaves are medium-sized, deeply lobed, with three or five lobes. Bunches are cylindrical or cylindroconical, medium-sized, and can be loose or compact.
The berries of the Matyas Janos variety are medium-sized, nearly round, bright vinous-red in color with a bluish bloom that turns purple as the berries ripen. The berry skin is relatively thick, and the flesh is fleshy and slightly crisp, with a distinct muscat aroma and low acidity. The sugar content of the berries is 17–19%, and acidity is 4–5 g/L, making them especially appealing for fresh consumption.
This variety requires careful management, including fertilization and protection from adverse weather conditions, as it is susceptible to mildew and gray mold. Its winter hardiness and cold tolerance are below average, which may result in significant losses of buds and shoots after open winter dormancy. For proper vine formation, pruning by the spur method on 5–7 buds is recommended. Despite these characteristics, the variety is popular due to the high quality of its berries and their muscat aroma.
