The variety received the 1976 Plant Variety Protection and in 1982 recommended to the list varietals added. In France, it is legal in all wine-growing regions except the region of Alsace. The crossing was made by the French ampelographers Paul Truel on the grounds of the Domaine de Vassal, trying Winery of the INRA Montpellier. The aim of the new variety was to create one of the Grenache similar variety that is suitable for a continental climate in the high altitudes of the Mediterranean. Since the variety matures very early, the risk of frosts in autumn and raw rot is minimized. Sensitive but the variety is resistant to powdery mildew and the Eutypiose.

In France, approximately 341 hectares of vineyards were planted in 2007 with Portan (Source ONIVINS, ). The largest share lies in the Aude department.
