The young shoot of the variety has sparse prostrate hairs at the tip and is practically devoid of anthocyanin coloration. The young leaf is green with anthocyanin spots, with veins devoid of pubescence. The mature leaf is pentagonal in shape, medium-sized, has a bullate structure and three lobes with closed petiolar sinuses.
The bunch is characterized by medium size and medium density. The variety is a wine grape and is of interest for the study of adaptation to drought and high temperatures, as well as the possibility of cultivation at altitude. Due to its relict status, detailed agronomic data on yield and disease resistance are limited.
