The variety is a wine grape intended for the production of red wines. It belongs to the category of "forgotten" varieties and is considered part of the cultural heritage of the Trièves region, where it is often cultivated using organic farming methods.
Genetic studies have confirmed the variety's origin from a cross between Gouais blanc and Chatus. Official data on agronomic characteristics, including maturity groups, disease resistance, and morphological traits of clusters or leaves, are absent in open sources.
