Dureza is a dark-skinned French wine grape variety from the Ardèche department of south central France in the Rhône-Alpes region. The grape is most widely known for being the father vine of Syrah—a discovery that confirmed that the Syrah vine was native to France and not introduced to the country from Persia, Sicily, Egypt or elsewhere, as had been speculated.
