Roman-era grape seeds reveal ancestry of modern wines

Updated: few hours ago

London, Jun 11 (PTI) A grape variety used in wine production in France today can be traced to an ancestral plant that was cultivated in the Roman Era, a study has found.

With the help of an extensive genetic database of modern grapevines, researchers were able to test and compare 28 archaeological seeds from French sites dating back to the Iron Age, Roman era, and medieval period.

Utilising similar ancient DNA methods used in tracing human ancestors, researchers from the UK, Denmark, France, Spain, and Germany, drew genetic connections between seeds from different archaeological sites, as well as links to modern-day grape varieties.

It has long been suspected that some grape varieties grown today, particularly well-known types like Pinot Noir, have an exact genetic match with plants grown 2,000 years ago or more, but until now there has been no way of genetically testing an uninterrupted genetic lineage of that age.
