This clone is characterized by more vigorous growth and the formation of larger bunches, ensuring a yield 20–25% higher than that of the original variety. In cool years, the grapes show better sugar accumulation performance, gaining 0.5–1.0 degrees more on the must scale.
The variety belongs to the earliest ripening group among Olaszrizling clones. It also shows lower susceptibility to powdery mildew (Oidium) compared to other variants of the variety.
