DNA From 2,000-Year-Old Tuscan Seeds Reveals White Grapes Dominated Roman Chianti

Summary
80 grape seeds recovered from wells at Cetamura del Chianti let researchers reconstruct the largest genetic history yet from a single ancient vineyard site.
DNA markers showed most seeds came from one long-lived white-grape clone that persisted from Etruscan into Roman times, overturning expectations in a region now famed for red sangiovese.
Roman conquest later coincided with the arrival of additional grape varieties, suggesting vines were introduced from elsewhere in the empire.
Two ancient seeds from southern France were closely related to the dominant Cetamura clone, giving biological evidence of long-distance Roman agricultural networks that may have shaped standardized winemaking.
Could ancient Roman DNA reveal the lost grape varieties that once connected an entire empire's vineyards?
If ancient Chianti was a white wine, why did the region become world-famous for its red?
From White to Red: How a 2,000-Year-Old Grape Discovery Is Transforming Chianti’s Wine Story
Overview
Groundbreaking research published in June 2026 has transformed our understanding of Chianti’s winemaking history. Scientists analyzed 2,000-year-old grape seeds excavated from deep Etruscan wells at Cetamura del Chianti, revealing that the region was once dominated by a white grape variety during Roman times. This discovery, led by Oya Inanli, Laurent Bouby, and colleagues, challenges the long-held belief that Chianti has always been known for its red wines. Instead, it shows that a rich tradition of white grape cultivation existed long before the rise of Chianti’s iconic reds, fundamentally rewriting the region’s historical legacy.
