Joubertin is a red French winegrape variety that was historically grown in the Savoie wine region of southeast France. The grape was once prized for its productivity and high yields but its plantings have declined as the grape has fallen out of favor and it is now on the verge of extinction.[1]
Various synonyms have been used to describe Joubertin and its wines including Jaubertin, Pinot Joubertin, Plant d´Aix, Plant de la Claye and Plant de la Mure.
