The variety is a complex hybrid requiring the training of vines with a large stock of perennial wood. The crop maturation period is 140 to 155 days. Own-rooted vines are characterized as weak- or medium-growing.
Bunches have a conical shape and medium density; their average weight is about 1 kg. Berries are large, round in shape, weighing 10–15 g, with a color ranging from ruby-red to brown. The flesh is firm and crunchy, with a neutral taste.
The variety has low to medium resistance to fungal diseases, including downy mildew and powdery mildew, and requires regular treatments. Agrotechnics include pruning to 6–8 buds and mandatory crop load regulation: no more than one bunch per shoot.
