Durif
Summary
Durif is a variety of red wine grape primarily grown in Australia, California, France, and Israel. Since the end of the 20th century, wineries located in Washington's Yakima River Valley, Maryland, Arizona, Texas, West Virginia, Chile, Mexico's Baja California Peninsula, and Ontario's Niagara Peninsula have also produced wines from Durif grapes. It is the main grape known in the U.S. and Israel as Petite Sirah, with over 90% of the California plantings labeled "Petite Sirah" being Durif grapes; the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) recognizes "Durif" and "Petite Sirah" as synonyms for the same grape. It produces tannic wines with a spicy, plummy flavour. The grape originated as a cross of Syrah pollen germinating a Peloursin plant. On some occasions, Peloursin and Syrah vines may be called Petite Sirah, usually because the varieties are extremely difficult to distinguish in old age.
In the 1860s the French botanist François Durif kept a nursery of several grape varieties at his home in the commune of Tullins where he most likely had plantings of both Peloursin and Syrah. At some point the two vines cross pollinated and Durif discovered a new grape variety growing in his nursery. It was identified and named Plant du Rif (later Durif) by ampelographer Victor Pulliat in 1868.
As a conclusion of DNA fingerprinting at the University of California, Davis in 1997, Syrah was identified as the source of the pollen that originally crossed with Peloursin flowers. The grape's high resistance to downy mildew encouraged its cultivation in the early 20th century in areas like Isère and Ardèche, although the relative low quality of the resulting wine caused the grape to fall out of favor with local wine authorities. Today, it is almost nonexistent in France.
Australia and California are now the two leading producers of Durif. The grape can also be found in Israel, Brazil, Argentina, Chile, and Mexico.
Confirmed as recently as 1997, old plantings of Durif continued to be used to produce popular wine in the Rutherglen, Victoria region of Australia.
