DNA from 2,000-year-old grape seeds points to origins of modern winemaking
Summary
Scientists studied DNA from 2,000-year-old grape seeds found in Tuscany, Italy, revealing that the grapevine varieties were part of the Roman Empire’s advanced farming system. The research showed that white grapes were most common at the site, which was surprising because the region today is known for red wines.Key Facts
