Ancient Grapes: Roman Chianti Grew White Berries
14 Jun
Summary
- DNA from ancient seeds reveals Roman Chianti primarily grew white grapes.
- Vineyards formed part of a sophisticated Roman agricultural network.
- Genetic links suggest long-distance trade of grape varieties across the empire.
Scientists have unveiled the most extensive genetic history of grapevines from a single ancient site, utilizing DNA from 2,000-year-old grape seeds found in Tuscan wells. The findings indicate that the Chianti region, now renowned for its red wines, was predominantly cultivating white grapes during Roman times.
The research, centered at Cetamura del Chianti, analyzed seeds preserved in oxygen-free mud. A dominant white-berried variety, passed from Etruscans to Romans, was maintained for centuries, surprising the research team. This discovery challenges the region's modern wine identity.
Following the Roman conquest of the settlement, new grape varieties emerged at Cetamura. Genetic analysis revealed the dominant ancient vine was closely related to seeds found in southern France, providing evidence of extensive agricultural networks across the Roman Empire. These networks may have influenced the standardized production of wine seen today.
