This red grape variety comes from the island of Sardinia(Italy). It must not be confused with the varieties Barbera, Barbera del Sannio or Carignan (Mazuelo), despite seemingly suggestive synonyms or morphological or name similarities. The parentage is unknown; possibly there is a relationship to the Barbera variety. The late-ripening vine produces red wines with a high acidity, which are mainly used as acid-boosting blends. It is grown exclusively in Sardinia, mainly in the provinces of Cagliari, Nuoro, Oristano and Sassari. In 2016, 70 hectares of vines were reported with a decreasing trend (Kym Anderson statistics).

I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
