Dureza is a dark-skinned French wine grape variety from the Ardèche department of south central France in the Rhône-Alpes region.[1] 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.[2][3]
It was historically used for production of red wine, but is hardly grown any more and is not part of the list of the allowed grape varieties of any French Appellation d'origine contrôlée wine though it can be produced under some vin de pays. In 1988 only 1 hectare of Dureza remained, while there were 11 ha in the late 1970s. However since the variety's relationship to Syrah was revealed, interested in Dureza has been increasing with Pascal Jamet introducing plantings of the grape to the Saint-Joseph AOC in the northern Rhône Valley for wine to be made under the Collines Rhodaniennes vin de pays.[2]
History
The Dureza vine is a member of the Vitis vinifera family of grape vines and is believed to be native to the northern Ardèche region of south-central France. At some point the vine spread eastward towards the Drôme and Isère regions. It was here that the variety likely came in contact with the Savoie wine grape Mondeuse Blanche where the two varieties created a natural crossing that became the international variety Syrah.[2]
Relationship to Syrah and other varieties
In 1998, DNA typing conducted at both the University of California-Davis and at the Institut National de la Recherche Agronomique in Montpellier established that Dureza was the father of the Syrah grape, with Mondeuse Blanche being the mother.[4][5][2]
Mondeuse Blanche is native to the Savoie region though it has been found in the Ain, Haute-Savoie and Isère department. The DNA evidence showing that Dureza, an Ardèche variety, and Mondeuse Blanche where the parent vines of Syrah helped to confirm that Syrah was indigenous French grape variety that originated somewhere in the Rhône-Alpes region with grape geneticist Dr. Carole Meredith speculating that the northern Isère region being the likely birthplace.[2]
DNA mapping has also revealed some relationship to the Italian wine grape variety Lagrein that is grown in the Trentino-Alto Adige/Südtirol region of northeast Italy though the exact relationship is unclear. The most recent research from Swiss grape geneticist Dr. José Vouillamoz completed in 2006 suggest that Dureza might be an "uncle" to Lagrein and connected together by another red Italian wine grape, Teroldego.[2]
Viticulture
Dureza is known as a vigorous vine, capable of producing high yields. The variety tends to ripening late in the season which linguist Jacques André and ampelographer Louis Levadoux have noted may account for the synonyms Serène and Serine being attached to the variety. Both synonyms, which are know more closely related to Dureza's similarly late-ripening offspring Syrah, are connected to the root of the Latin term serus which means "late".[2]
Synonyms and confusion with other varieties
Dureza is also known under the synonyms Duré, Duret, Durezza (when grown in the Annonay commune of the Ardèche) and Petite Duret (in the Drôme and Isère departments).[6] Historically it has also been known as Serène and Serine which are more widely recognized as synonyms for its offspring Syrah used in the Côte-Rôtie AOC.[2]
Dureza has sometimes been confused with Durif (which is also known as Petit Sirah), Peloursin (which is known under the synonyms Duresa, Dureza and Durezi) and Syrah.[2]
