It has small compact clusters and small berries. It is very sensitive to grey rot, with late bud break but early ripening. As for the wine parameters, it has high colour intensity and anthocyanin content, high acidity and medium alcohol content. Sensorially, it stands out for its purple colour, typical varietal aromas of green peppers with balsamic and spicy notes, a well-structured mouth with notable acidity and tartness and medium persistence.
It is not grown anywhere else in the world, making it a very interesting grape to support the uniqueness, differentiation and diversity of Rioja wines. DNA analyses seems to relate it to the Castets variety, which has practically disappeared in France, its country of origin.
