Grapevines, Graves, and Global Trade: 4000 Years of Wine History in France

Grapevines, Graves, and Global Trade: 4000 Years of Wine History in France

This comprehensive study follows 49 tiny grape pips – waterlogged seeds, dark and shrivelled but miraculously preserved – to tell a sweeping story of how grapevines were domesticated, traded, and carefully cloned across what is now France over roughly 4000 years. From Bronze Age river channels to Medieval town plots, each pip becomes a witness to changing tastes, trade routes, and agricultural know-how, revealing an extraordinary tale of botanical continuity and human ingenuity.

Bronze Age: Wild Vines in the River at Nîmes

The story begins in southern France, at Nîmes, between about 2300 and 2000 BCE. Here, archaeologists recovered grape pips from a former watercourse, a palaeochannel, where seeds were washed in and buried in wet mud. These seeds look and behave genetically like today's wild European grapevines, belonging to a wild western lineage that is still common in France's forests today. Intriguingly, several of the Nîmes pips are genetically identical – effectively from the same plant. In the wild, this most likely means that all those pips came from a single wild vine that had shed its fruit into the stream, rather than deliberate vineyard planting. At this stage, there is no sign that people in France were yet cultivating vines. Wine culture existed elsewhere, but here the vines were still part of the woodland, creating a baseline for understanding the dramatic transformations to come.

Iron Age Villages and Ports: Wild Grapes Meet Domesticated Vines

By the Iron Age, the scene shifts to a chain of remarkable sites in southern France. They form a patchwork of inland settlements and bustling coastal hubs, all caught up in Mediterranean trade. At Saint-Maximin, an inland Iron Age settlement around 625–500 BCE, researchers find the earliest pip in France whose genetic profile matches fully domesticated grapevines. This is precisely the time Greek settlers were founding Marseille on the coast. Marseille itself, dating from 600–400 BCE, also yields grape pips whose genetic signatures match domesticated vines. One pip from Saint-Maximin is genetically identical to a pip from Iron Age Marseille, even though the sites lie about 40 kilometres apart. This suggests that vine cuttings – not just wine – were moving between a major Greek port and its indigenous hinterland.

At Lattes, an important coastal settlement near the lagoon, pips dating between about 500 and 25 BCE tell an especially rich story. Some belong to truly wild French lineages. Others look like imports, genetically close to vines from the Balkans, Iberia and even further east. Still others are clear mixtures of wild and cultivated ancestry, implying deliberate or accidental crossing. One pip from Lattes carries almost 40% wild ancestry mixed with domesticated traits. It is a literal hybrid, capturing the moment when winegrowers began to draw local wild vines into the cultivated pool, perhaps seeking hardiness or adaptation to local soils and climate.

At Martigues, another coastal Iron Age site from 300–200 BCE, and at inland Vieille-Toulouse from 125–100 BCE, domesticated grapes again appear in the archaeological record. At Martigues, one domesticated genetic line appears again centuries later in Roman-period pips from Mauguio and Lattes, showing that this Iron Age cultivar did not vanish; it was carried forward into the new Roman world.

Roman Gaul: A Patchwork of Varieties and Far-Flung Origins

Under Roman rule, France – or Roman Gaul – becomes a dense network of vineyards, wine workshops and trade depots. Most of the pips in the study come from this period, recovered from wells, ditches, and waterlogged layers at sites scattered across the country. In southern towns such as Nîmes, Mauguio, Valros, Antibes and Magalas, Roman layers dating roughly from 0 to 400 CE yield pips whose genetic make-up is dominated by lineages now typical of French and Spanish wine grapes. These were the workhorse vines of Roman Gaul, already close cousins of the varieties that still underpin western European viticulture.

Yet this is no closed provincial market. Some Roman pips carry ancestry linked to grapes of the Levant and the Caucasus – regions associated with some of the earliest winemaking. A pip from Mauguio and pips from Valros and Horbourg‑Whir in the north-east display clear traces of these eastern lineages. Others show contributions from Balkan-type grapes. These long-distance arrivals likely came in as cuttings or perhaps as pips in imported fruit or wine residues, then crossed with local stock.

Roman wine was not confined to Mediterranean shores. At Troyes in northern Gaul from 33–200 CE and Horbourg‑Whir in the north-east from 0–50 CE, waterlogged seeds again reveal a mix of local and foreign heritage. Some pips are strongly linked to the French lineage, others have a Spanish tilt, and some carry traces from the Balkans and Caucasus. Limoges, in central France from 170–240 CE, yields a domesticated grape that will later prove to be a direct clonal ancestor of a Medieval vine far to the north. Already in the Roman period, growers in the interior were cultivating lines that would still matter many centuries later.

Evidence for Clonal Vines Moving Across the Empire

A striking feature of this research is the detection of genetically identical vines – clones – at different Roman sites. One particular clone turns up in Horbourg‑Whir in the north-east and also at Mauguio and Valros on the Mediterranean coast, more than 500 kilometres away. The most straightforward explanation is that cuttings from the same cultivar were moved through trade or estate networks and planted in widely separated vineyards. Other vines are not identical but closely related, equivalent to first- or second-degree relatives in human terms. For example, a grape grown at Iron Age Martigues appears as a near-relative in Roman Antibes and then again in Medieval Ibiza. Over more than a thousand years, this lineage seems to have passed through only a handful of sexual generations, with most reproduction achieved by cuttings.

Together, these patterns show that vegetative propagation – growing vines from cuttings so that each plant is genetically the same as its parent – was already a central part of viticulture by the mid-Iron Age and was commonplace under Rome. The vineyards of Gaul were not shifting patchworks of seed-grown plants; they were structured by enduring named or at least recognized varieties.

Medieval Grapevines: Old Roman Lines and Famous Names

The research does not stop with the end of empire. Medieval pips from Aurillac, Auvillar, Nîmes, Valenciennes and the island of Ibiza show that the Roman genetic mosaic persisted into a Christian, feudal world – and that some vines we know today were already in place. In Aurillac from 800–900 CE, a pip carries a strong dose of ancestry linked to grapes from the Levant and Central Asia. At Auvillar from the 11th–13th centuries, pips again show the familiar French and Spanish lineages, but with continued traces of more distant contributions from wild eastern vines. Medieval viticulture in inland France was still drawing on a deep and mixed genetic pool set up in earlier centuries.

Two Medieval pips from Ibiza, dating from 1027–1160 CE, reveal close kinship with Iron Age and Roman vines from southern France. One of these Ibiza seeds is genetically identical to a modern Portuguese white grape, 'Folha de Figueira'. This shows that a cultivar still grown today on the Atlantic fringe was already travelling around the western Mediterranean a thousand years ago, its cuttings moving between islands and coasts.

Perhaps the most eye-catching episode comes from Valenciennes in northern France, where waterlogged layers from the later Middle Ages produced grape pips dated between about 1100 and 1500 CE. These belonged to vineyards in a northern town well outside the classical heartlands of Mediterranean viticulture. Two pips from Valenciennes are genetically dominated by the same western European lineage that defines many modern French wine grapes. When compared to a broad panel of living varieties, one Medieval pip from Valenciennes matches modern 'Pinot Noir' exactly: they are clones of the same plant line.

This means that by the 14th or 15th century, a vine genetically indistinguishable from today's 'Pinot Noir' was already being cultivated, far from Burgundy itself. The research also notes that 'Pinot Noir' has many close relatives across Europe and is a key parent of other famous grapes. Here, the Medieval pip from Valenciennes becomes a single, tangible point where Medieval viticulture and the modern global wine industry are literally joined at the seed.

Graves, Channels, and Town Ditches: The Archaeological Settings

What gives this study its distinctive flavour is the variety of archaeological contexts in which the pips were found. Many come from waterlogged layers: ancient river channels at Nîmes, town ditches at Lattes and Troyes, wells and wet pits in Roman and Medieval settlements. These damp, airless conditions preserved not only the shape of the seeds but also their DNA. Some sites, such as Lattes, Martigues and Saint-Maximin, are rich protohistoric settlements where houses, workshops and graves crowd along trackways and harbours. Others, like Limoges and Aurillac, are later urban centres, where grape pips lie in the backfill of pits and drains alongside pottery, animal bones and other everyday refuse. At Valenciennes, the seeds come from Medieval urban deposits in a northern town that would never make a modern wine map, yet harboured one of the most important cultivars of all.

These pips are not funerary offerings but remnants of pressing, winemaking and discard – yet they serve a similar role to that of richly furnished burials. Each seed ties local communities to distant regions: Greek traders at Marseille, Roman merchants hauling amphorae along the Rhône, Medieval growers on Ibiza swapping cuttings linked to Portuguese vineyards.

Wild and Cultivated Encounters

The research reveals a Mediterranean world in motion, where grape varieties did not stay politely at home in their native valleys. Instead, they travelled by ship and cart, tucked into amphorae, baskets, and bundles of cuttings, moving between the Levant, the Caucasus, the Balkans, Iberia and what is now France. Ancient DNA from grape pips found in wells, ditches, and harbour mud shows that the vineyards of Roman and earlier Gaul were already global in outlook. The wild grapevines show a remarkable genetic stability across this entire time span. When focusing on clearly wild individuals, their DNA remains stubbornly wild, with no detectable input from cultivated vines, despite the spread of viticulture around them. This matches modern observations in southern France, where pollen from vineyards hardly ever manages to leave a lasting genetic mark on wild populations.

If anything, the movement of genes tends to go the other way: from wild into cultivated vines. This fits previous genomic work showing that most introgression – that is, genetic mixing – has been from wild vines into vineyards, not from vineyards back into the wild. Hybrids seem to do poorly if they try to live unaided in forests, but they can be very useful in managed vineyards.

From Wild Forest Vines to Cloned Medieval Classics

Across all these sites and centuries, the research uncovers a long arc. In the Bronze Age, the forests of southern France already housed the wild grape lineages that still ramble along riverbanks today. In the Iron Age, Greek-style viticulture arrived, bringing domesticated vines, while local growers experimented with crossing these with native wild stock. Under Rome, Gaul's vineyards filled with a blend of local and imported varieties, some carrying genes from as far away as the Caucasus. Cuttings of prized vines were moved up and down the Rhône valley, across to the Rhine frontier, and out into the western Mediterranean. In the Middle Ages, many of these lines persisted, now woven into monastic estates, town gardens and island plots – and among them, early forms of 'Pinot Noir' and a Portuguese white that are still with us.

By following seeds from muddy channels and town ditches, this research turns French viticulture from an abstract tradition into a set of very specific vines, travelling bodies of plant material, maintained by careful human hands from the Bronze Age woodland to the cellars of the modern wine trade. The archaeological sites themselves become way-stations in the biography of these long-lived plant individuals, whose cuttings moved with merchants, settlers, and pilgrims – and whose descendants still fill bottles today. Each tiny seed becomes a witness to 4000 years of human choices, environmental adaptation, and the patient work of countless generations who selected, propagated, and cherished particular vines across the changing landscapes of France and the wider Mediterranean world.
