Syrah has a long documented history in the Rhne region of Southeastern France, and it was not known if it had originated in that region. In 1998, a study conducted by Carole Meredith’s research group in the Department of Viticulture and Enology at University of California, Davis used DNA typing and extensive grape reference material from the viticultural research station in Montpellier, France to conclude that Syrah was the offspring of the grape varieties Dureza (father) and Mondeuse Blanche (mother).
Dureza is a dark-skinned grape variety from the Ardche region in France that has all but disappeared from the vineyards, and the preservation of such varieties is a speciality of Montpellier. Mondeuse Blanche is a white grape variety cultivated in the Savoy region, and is still found in very small amounts in that region’s vineyards today. Both varieties are somewhat obscure today and have never achieved anything near Syrah’s fame or popularity, and there is no record of them ever having been cultivated at long distances from their present home. Thus, both Syrah’s parents come from a limited area in southeastern France, very close to northern Rhne. Based on these findings, the researchers have concluded that Syrah originated from northern Rhne.
The DNA typing leaves no room for doubt in this matter, and the numerous other hypotheses of the grape’s origin which have been forwarded during the years all completely lack support in form of documentary evidence or ampelographic investigations, be it by methods of classical botany or DNA.
Instead, they seem to have been based primarily or solely on the name or synonyms of the variety. Because of varying orthography for grape names, especially for old varieties, this is in general very thin evidence. Despite this, origins such as Syracuse or the Iranian city of Shiraz have been proposed.[6]
The parentage information does however not reveal how old the grape variety is, i.e., when the pollination of a Mondeuse Blanche vine by Dureza took place, leading to the original Syrah seed plant. In the year AD 77, Pliny the Elder wrote in his Naturalis Historia about the wines of Vienne (which today would be called Cte-Rtie), where the Allobroges made famous and prized wine from a dark-skinned grape variety that had not existed some 50 years earlier, in Virgil’s age.[7] Pliny called the vines of this wine Allobrogica, and it has been speculated that it could be today’s Syrah. However, the description of the wine would also fit, for example, Dureza[2] and Pliny’s observation that the vines of Allobrogica was resistant to cold is not entirely consistent with Syrah.
