Peloursin is both the Durif grape of southern France and not the Durif at the same time. Either way, you would be hard pressed to find a wine outside of the south of France made from the Peloursin.
Long thought to be the Petite Sirah common in California, the Durif is a variety that originated in southern France in the 19th century when it was born from a cross of the obscure Peloursin and the more widely known Syrah. Petit Sirah can be one of a number of different clones so it is of no surprise that that name is used as a synonym. Durif wines are heavy and tannic, with notes of red and black currants. Durif was common in the southern French regions of Languedoc, Provence and Vin de Pays though it is rarely seen today.
