A recent study has traced the genome of Pinot Noir grape seeds found in a medieval rubbish pit in Valenciennes, France, suggesting that this grape variety has been present for longer than previously thought. The research indicates that Pinot Noir has changed little over the last 600 years, preserved through clonal propagation techniques. Winegrowers are now seeking to revive ancient grape varieties for their resilience and insights into climate change. The study also highlights the historical trade of grape varieties across the Mediterranean, revealing long-distance exchanges dating back to ancient times.
