An international team of archaeologists and geneticists have compared the genomes obtained from 28 grape pips, discovered at nine archaeological sites in France, the oldest pip dating to some 2,500 years ago. These genomes were then compared to a modern grape DNA database. One grape seed, unearthed at a medieval site in the center of France and dated to around 1100 CE, was found to have DNA identical to Savagnin Blanc. That’s the grape used to produce a wine known in France as Vin Jaune, and in Central Europe as Traminer. The lineage of this one grape has been maintained for 900 years!
The study also found that humagne blanche, a white grape grown in the Swiss Alps, is related to grapes grown by the Romans in southern France. It confirms stories of the Romans bringing grapes and wine into Switzerland.
