Researchers also discover that the ancient vines of Chianti, famed for its red wines, produced white fruit

DNA extracted from 2,000-year-old grape seeds found in ancient wells in Tuscany has enabled scientists to map the most extensive genetic history of grapevines recovered from a single site, revealing that vineyards of the Roman era formed part of the empire’s sophisticated agricultural network that might have influenced the development of modern winemaking.

The research led by scientists at the University of York also found that white grapes once dominated the site in Chianti, an area of Tuscany famous for its red Sangiovese wines.
