Muscardin is believed to be a clone the Mondeuse varietal of the Savoie region of France. It is one of the 13 permitted varietals in Châteauneuf-du-Pape, but has virtually disappeared; Château de Beaucastel and Château Rayas are among the only domaines that include it in their red blends. It has a distinctive floral bouquet and is pale in color.
