A recent scientific study has uncovered fascinating insights into the ancient history of wine production in France, revealing that humans have been cloning grapevines—including the globally celebrated pinot noir variety—for over two millennia. This discovery not only sheds light on the origins of viticulture in one of the world’s most renowned wine regions but also highlights the deep cultural and biological connections humans have shared with wine throughout history.
Wine has long been intertwined with human civilization, celebrated in art, literature, and religious texts across the globe. From frescoes in Pompeii to mentions in the Bible, and from traces found in King Tutankhamun’s tomb to 9,000-year-old pottery in China, wine’s presence is a testament to its enduring significance. Yet, despite its prominence, the exact timeline and methods by which humans first produced wine as we know it today have remained elusive. Scientists have grappled with understanding when and how early humans transitioned from merely gathering wild grapes to intentionally cultivating and propagating specific grape varieties for winemaking.
This puzzle has become clearer thanks to a recent study published in the journal Nature Communications. Researchers analyzed the DNA extracted from nearly 50 ancient grape seeds—referred to as pips—unearthed from archaeological sites across France. These seeds span an extensive historical range, dating from approximately 2300 B.C.E. during the Bronze Age, through the Iron Age, and up to around 1500 C.E. in the late Middle Ages. This nearly 4,000-year window offers a rare, long-term perspective on grape cultivation and winemaking practices in a region famed for its viticulture.
One of the study’s senior authors, Ludovic Orlando, a research director at the Center for Anthropobiology and Genomics of Toulouse, described the findings as “very surprising.” By comparing the DNA of these ancient seeds with those of modern grape varieties, the researchers identified clear genetic evidence that ancient winemakers in France were not simply domesticating wild grapes but had begun cloning grapevines as early as the mid-Iron Age, around 500 B.C.E. This means that instead of breeding new grape varieties through seeds—which introduces genetic variability—these early vintners were propagating grapevines by taking cuttings from existing plants, ensuring that new vines were genetically identical to the parent. This practice of cloning allowed winemakers to maintain desirable traits consistently across generations.
Perhaps the most striking revelation from this genetic analysis was the identification of a medieval grape seed, dating back to the 15th century, that was genetically identical to the pinot noir grape variety still widely cultivated and adored today. Pinot noir is renowned globally for its delicate flavor profile and is a cornerstone of many prestigious wines. Orlando noted the remarkable continuity, stating, “We found the very same plant, 600 years ago in the 15th century—the century of Joan of Arc.” This discovery illustrates that pinot noir has not only persisted through centuries but has been carefully preserved and propagated through cloning to maintain its precise genetic makeup. The grape variety’s enduring popularity underscores the value placed on its unique qualities by generations of winemakers and consumers alike.
While the genetic data can confirm the identity and propagation methods of ancient grapevines, it offers limited insight into the flavor of wines produced from these grapes centuries ago. Wine’s taste is influenced by a complex interplay of factors including the grape variety, fermentation techniques, environmental conditions (terroir), and winemaking additives. Orlando emphasizes that wine is “a complex biocultural product,” reflecting both biological and cultural elements. Although DNA can reveal certain traits such as sugar content and grape size, the sensory experience of wine—its aroma, texture, and flavor—remains shaped by many variables beyond genetics alone.
This research not only advances our understanding of the history of viticulture but also highlights the broader relationship between humans and their environment. Wine serves as a lens through which we can view human culture, preferences, and technological innovation across millennia. The deliberate cloning of grapevines in ancient France reveals an early sophistication in agricultural practices and an appreciation for the qualities that certain grape varieties could bring to wine. As Orlando reflects, “Think about which your favorite wine or my favorite wine—it tells something about you, as well as about your culture.”
The study’s findings resonate with the ancient proverb famously quoted by Pliny the Elder: “In wine there is truth.” This truth extends beyond the beverage itself to the story of human ingenuity, tradition, and continuity. By
