Humagne rouge is a grapevine variety originated from the Aosta valley (Italy) but it is primarily cultivated in the Valais (Switzerland). A grey form of this variety was observed for the first time in 2000 on a shoot of a Humagne rouge vine in the experimental vineyard of Agroscope RAC Changins at Leytron (VS). The grafting material resulting from this vine shoot was multiplied and introduced in the collection of the Centre viticole du Caudoz in Pully. The grey character of the berries could be confirmed in 2004 on all the bunches carried by the vines of third year. We propose to name this new varietal form «Humagne gris».
