The variety has medium to small, dense, conical bunches. The berries are medium-sized, oval-shaped, dark blue in color with a thick waxy bloom and skin of medium thickness. The leaf is rounded, five-lobed, with characteristic dense pubescence on the underside. The flower is hermaphroditic.
The variety reaches maturity in medium to medium-late terms. It is characterized by low yield and weak resistance to frost, fungal diseases, and grey rot. Due to the presence of many synonyms, the variety is often confused with other grape varieties, such as Graciano or Mazuelo.
