Archaeological excavations at the ancient site of Cetamura in Tuscany, Italy, have uncovered 2,000-year-old grape seeds from deep wells, whose ancient DNA analysis reveals that the Chianti region—now world-renowned for its red wines—was predominantly cultivating white grape varieties in antiquity. This discovery, dated to the Etruscan and Roman periods, completely redefines the region’s viticultural history and provides the most comprehensive genetic map of grape varieties to date, offering unprecedented insight into the origins of modern winemaking.
Genetic Legacy from Ancient Wells
Seeds recovered from ongoing excavations led by Nancy De Grummond of the University of Florida since 1973 demonstrate that ancient viticulture was far more advanced than previously assumed [1]. Led by researchers from the University of York, the genetic studies have produced the most extensive grape genome map ever derived from a single archaeological site [2]. These analyses confirm that Chianti, now synonymous with Sangiovese red grapes, possessed a completely different agricultural identity during classical antiquity.
Roman Empire’s Trade Networks
Researchers emphasize that the data not only illuminate grape varieties but also shed light on the vast agricultural and trade networks across the Roman Empire [2]. These ancient systems are considered foundational to today’s standardized wine production [3]. The genetic evidence demonstrates that grapevine varieties have persisted through centuries of migration, conquests, and cultural transformations, surviving to the present day across Europe.
Proof of Historical Continuity
Experts stress that while ancient white wines may not taste identical to modern counterparts, they exhibit strong genetic continuity. Although this discovery does not alter Chianti’s modern identity, it fundamentally updates historians’ and wine specialists’ understanding of the deep roots of the region’s winemaking tradition.
