Is Terroir Real? The Hundred-Year Fight Over What Makes a Great Wine Great

Roger Dion called terroir a social fact; Enjalbert and Pijassou answered with the soil. A century of scholarly debate over what makes a great wine great.

Walk into any tasting room in Bordeaux and you will hear the same story. The gravel banks of the Médoc, dropped by ancient rivers, drain the winter rain away from the vines and hold the summer heat; the limestone beneath Saint-Émilion gives Merlot its finesse; and this singular marriage of soil, subsoil, slope and climate — terroir — is why a great growth tastes like nothing else on Earth. The land made the wine. It was always going to.

For the better part of a century, professional historians and geographers have been arguing about whether that story is true — and the argument has never been settled. It is one of the richest debates in wine scholarship, and almost none of it ever reaches the back label. What follows is the debate itself, with each side given its strongest case.

The story everybody tells

The popular account of Bordeaux is geological. The Médoc's great estates sit on croupes — low gravel rises left behind by ancient rivers — that drain freely, force roots deep and reflect warmth onto ripening Cabernet Sauvignon. Saint-Émilion has its limestone plateau, Pomerol its clays; the Graves are literally named for their gravel. In this telling, the map of great wine is a map of soils, and the famous classifications merely ratified what nature had already decided. Terroir, in the consumer version, is destiny: the great vineyards were always great, and humans simply discovered the fact.

It is a satisfying story, and nearly every wine label, tour and website repeats some version of it. It is also precisely the story that the founder of modern French wine historiography set out to dismantle.

Roger Dion: terroir as a "social fact"

Roger Dion, a geographer and historian who held a chair at the Collège de France, published Histoire de la vigne et du vin en France, des origines au XIXe siècle in 1959. Reviewed at length by medievalists on its appearance — Wolff's 1962 notice in the Cahiers de civilisation médiévale among them — the book is still in print with CNRS Éditions and is still routinely described as the unmatched reference in the field. Its central thesis was, and remains, a bombshell: the hierarchy of French vineyards is a "fait social et non géologique" — a social fact, not a geological one.

Applied to Bordeaux, Dion's argument runs like this. The classified growths owe their wealth not to any inherent superiority of their soils but to a commercial strategy pursued since the Middle Ages: the deliberate production of quality wines for elite export markets, above all the English one. The turning points that historians can actually document in Bordeaux's rise are commercial, not geological — the thirteenth-century English trade that made Bordeaux the kingdom's wine port, the privileges that protected its wines from upstream competitors, the Dutch merchants' technical innovations of the seventeenth century, the invention of luxury claret for London around 1700. Where sustained elite demand existed, capital and expertise followed, and quality — with its price — was built, plot by plot, over centuries.

One point must be stated carefully, because Dion is routinely caricatured on it: he never claimed that soil does not matter. In his account, soil and climate are necessary but not sufficient. Favourable land is a precondition of a great vineyard — but favourable land is far more common than great vineyards. What separates a famous gravel rise from an anonymous one, he argued, is not the gravel; it is history — nearness to markets, and the accumulated decisions of merchants, proprietors and states.

The answer from the soil: Enjalbert, Pijassou and the Bordeaux school

The opposing position was staked out by the geographers of Bordeaux itself — and, in print, even before Dion's book appeared. In 1953 Henri Enjalbert published an essay whose title announces its programme: "Comment naissent les grands crus" — how great growths are born. For Enjalbert, the distribution of the great growths is no accident of commerce: it tracks specific, mappable physical conditions, and the task of the geographer is to identify them. The two theses would confront each other for decades.

Enjalbert's student René Pijassou gave that school its monument. Un grand vignoble de qualité : le Médoc (Flammarion, 1980) — two volumes, 42 plates, 196 figures — remains the academic reference on the Médoc, saluted in a major review by the geographer Louis Papy in the Annales de Géographie in 1983. Pijassou worked the archives and the ground at a scale no one has repeated, and in his pedology-centred account the physical endowment of the Médoc's gravel croupes plays the decisive role that Dion had denied it: the great estates and the finest gravels, he argued, coincide for a reason.

This was a school in the institutional sense too. In 1969–70, Alain Huetz de Lemps as director, together with Papy, Enjalbert, Pijassou and Philippe Roudié, founded CERVIN, a Bordeaux centre for research on vine and wine — a body that survives today as an association of researchers hosted at the ISVV, Bordeaux's institute of vine and wine science. The terroir school, in other words, did not merely answer Dion; it organised.

Round three: the deconstructionists

Since the 1990s a third wave has entered the ring, much of it anthropological and Anglophone. Robert Ulin, from his ethnography of Bordeaux's cooperative growers, argued that terroir functions as an ideology — a way of presenting a hierarchy built by history as if nature had ordained it. Marion Demossier, working on Burgundy, has analysed terroir as a constructed identity that growers perform as much as inherit. The historian Kolleen Guy has shown how wine regions were woven into French national identity itself, and Amy Trubek has traced how the "taste of place" was elaborated as a cultural category. A 2019 article in Global Food History, "Geographical Turns and Historical Returns in Narrating French Wine Culture", surveys this literature and its running argument with the geographers.

The point is not that this wave has won. Soil scientists and geographers continue to defend, refine and map the physical basis of appellations, and the deconstructionists continue to historicise them. The debate is live — conducted in journals and monographs, not settled in anyone's favour.

What both sides concede — and why it matters

Strip away the caricatures and the two camps are closer than their rhetoric suggests. Dion himself granted the physical preconditions: no one builds a great vineyard on land that cannot ripen grapes. And the pedological school never wrote soil-only history: Pijassou's two volumes devote hundreds of pages to proprietors, merchants and the London market alongside their soil maps. Both sides accept that great wine appears where favourable natural conditions meet centuries of sustained demand, capital and human choice. The fight is over the weighting — and over what the word terroir smuggles past you when it is used as a one-word explanation.

That is why the debate matters beyond the seminar room. When a back label credits a "unique terroir" for a wine's character and price, it is taking a position in a scholarly argument while pretending no argument exists. The classifications the trade still lives by were drawn up by brokers ranking estates on their long-run market prices — and whether those prices tracked geology, as Enjalbert and Pijassou maintained, or a market built by centuries of commercial strategy, as Dion insisted, is precisely the question. A hundred years in, the honest answer is both, in proportions still being argued — which is worth remembering the next time a label offers you geology alone.
