Ancient Tuscan grape DNA rewrites winemaking history

Researchers extracting DNA from 2,000-year-old grape seeds found in ancient wells across Tuscany have traced the genetic ancestry of modern European winemaking back to Roman times, the Guardian reported this week. The discovery maps the most extensive genetic history of grapevines recovered from a single archaeological site, revealing that the vines which gave rise to Chianti's red wines once produced white fruit. The findings illuminate how viticulture evolved across central Italy during the Imperial period and beyond.

The research carries implications for understanding how grape varieties spread and adapted across the Apennine regions. Abruzzo, like Tuscany, sits at the heart of Italy's wine belt and shares similar continental and Mediterranean climates that shaped ancient and modern viticulture alike. The genetic markers recovered from Tuscan wells offer a baseline for tracing how varieties migrated southward and adapted to the higher elevations and cooler winters of the Apennine interior, where Abruzzo's own wine traditions took root.
