The variety possesses weak to moderate vine vigor. Leaves are medium or small in size, dark green, entire to five-lobed, with a characteristic blistered surface. Bunches are medium to large, cylindrical-conical in shape, and fairly dense. Berries are medium, round or short-elliptic, acquiring a greenish-yellow or golden hue with dark spots upon ripening.
Buds break early, which makes the variety vulnerable to spring frosts; berry ripening time is medium to late. The variety is distinguished by high fertility and yield, however, it is sensitive to powdery mildew, gray mold, and sour rot, showing only moderate resistance to downy mildew and black rot. The resulting wines are usually light, with pronounced acidity.
