Ancient Chianti vines bore white grapes, DNA reveals

Researchers have extracted DNA from 2,000-year-old grape seeds discovered in ancient wells across Tuscany, revealing that the vineyards of Roman-era Chianti—the region now synonymous with red wine—actually produced white grapes. According to the Guardian, the analysis represents the most extensive genetic history of grapevines recovered from a single archaeological site, and demonstrates that Roman vineyards formed part of the empire's sophisticated agricultural network. The finding challenges the popular narrative of Chianti as a continuous lineage of red-wine production stretching back to antiquity.

The discovery carries particular weight for Tuscany's wine identity and its standing in the international market. Chianti's global brand rests partly on historical narrative—the idea of unbroken tradition and terroir rooted in Roman times. The Guardian's reporting suggests instead that the region's viticultural character has shifted fundamentally over two millennia. The white-producing vines of the Roman period gave way to the red varieties that define modern Chianti Classico and Chianti DOCG wines.
