The variety is late-ripening: the period from bud burst to berry maturity takes 145–155 days, requiring an active temperature sum of approximately 3200°C. Vines are characterized by medium vigor and good cane maturation. Leaves are medium-sized, round, three- or five-lobed, and slightly dissected. The flower is hermaphroditic. Bunches are medium-sized, cylindro-conical, often winged, and of medium density.
Berries are white with a greenish tint, medium-sized, round, and possess a firm skin and juicy flesh. The variety is distinguished by high yield (9–13 t/ha) and the ability to maintain high acidity in hot climates. Wines from this variety have a light, fresh profile with aromas of citrus, green apples, and tropical fruits.
The variety has medium resistance to downy mildew and berry rot, while being sensitive to autumn frosts. Like other wine varieties, it requires regular training and shoot tying.
