The parentage information, however, does 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 Côte-Rôtie), 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. 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, and Pliny's observation that vines of Allobrogica were resistant to cold is not entirely consistent with Syrah.
