Insights

  • Scientists sequenced genomes from 54 grape seeds dated from the Bronze Age to the Middle Ages.
  • A 15th-century seed from a Valenciennes rubbish pit matches modern Pinot Noir, though researchers cannot tell if it was eaten or fermented.
  • Pinot Noir shows little genetic change over about 600 years because of clonal propagation.
  • Vegetative propagation appears from the middle of the Iron Age and persisted across sites and centuries.
  • Ancient DNA reveals long-distance transfers of domesticated grapes across the Mediterranean from Spain, the Balkans, the Caucasus and the Middle East.
