Researchers conducted DNA tests on 28 samples of grape seeds dug out of waterlogged wells, dumps and ditches at archaeological sites across France. The results, published today in the journal Nature Plants, show strong connections between modern wine grapes and those used as far back as the Roman period.
To propagate grapevines, farmers often use cuttings from a preferred plant to grow new, genetically identical vines. The practice means that, theoretically, the DNA of an ancient grape and a modern grape of the same variety should be the same. Though many wine varieties we know and love allegedly have ancient pedigrees, it’s hard to know whether the pinot noir or syrah we drink today is really the same type of wine that filled the cups of French monks or Roman magistrates.
