Gueuche noir

Gueuche noir is a red French wine grape variety that has been historically grown in the Franche-Comté of eastern France but is now close to being extinct. Though its exact relationship has not yet been determined by DNA analysis, ampelographers believe that the grape variety is closely related to the Hunnic grape Gouais blanc which is notable for being the mother vine to several grape varieties including Chardonnay and Gamay. There also might be a relationship between Gueuche noir and the Jura wine grape Enfariné noir.
