Saint-Julien: Vineyards, Cellars, People, and Place is the latest addition to the Académie du Vin Library's Exploring the Appellations of Bordeaux series, written by Marc Bouffard. Compact in geography but outsized in reputation, Saint-Julien is home to some of the Médoc's most celebrated Grands Crus Classés — and this book sets out to explain, with rigour and warmth, exactly why.
Bouffard approaches the appellation from the ground up, opening with a meticulous account of Saint-Julien's terroir: the two glacial gravel terraces shaped over 2.5 million years, the moderating influence of the Gironde, and the 17th-century Dutch drainage works that transformed a swampy peninsula into one of the world's great wine regions. He then turns to the human story — the winemakers, the châteaux, and the restless spirit of innovation that has defined Bordeaux from Peynaud's fermentation breakthroughs to today's precision viticulture and climate adaptation.
The result is a book that rewards both the curious newcomer and the seasoned Bordeaux enthusiast. It is a portrait not just of an appellation, but of a living community of growers and thinkers who, as Bouffard puts it, are still very much succeeding — vintage after challenging vintage. The two passages below, drawn from different points in the book, offer a taste of both its scope and its spirit: the first plants us firmly in the land itself; the second lifts the gaze toward history, science, and the future.
The lie of the land
Most readers who decide to open a book dedicated to Saint-Julien will not be novices to Bordeaux, but I think this isn't the worst place to start for those who are. Regardless of the level of expertise, there's some setting of the scene that needs to be done as a basis for the coming focus on Saint-Julien's Grands Crus Classés. This begins with the AOC's terroir. Bordeaux is divided into two banks by the Gironde estuary, itself formed from the rivers Garonne (originating in the Pyrenees) and Dordogne (coming from the Massif Central). Saint-Julien sits on the Left Bank of the Gironde on the Médoc peninsula. The waters of the Gironde play a major influence in the AOC's terroir, cooling it when weather is hot and heating it when weather is cool, with the numerous influences on ripening in moderation, promotion of air flow, and mitigation of threats such as frost.
In her excellent work Inside Bordeaux (2020), Jane Anson delivers a wonderful masterclass in geology as it pertains to Bordeaux's formation and soil types. Most pertinent to the understanding of Saint-Julien is that cycles of glacial formation and melting beginning 2.5 million years ago led to sequential periods of erosion in the Pyrenees and deposition of gravel onto the Médoc peninsula. The eras in which these deposits were made bear the names 'Mindel' and 'Günz'; they form two terraces – Terrace 3 and Terrace 4. The latter is closer to the Gironde and is home to the three Léoville châteaux, Langoa Barton, Ducru-Beaucaillou, and Beychevelle. Terrace 3 is home to the estates in the western half of the appellation.
The two terraces are gravel-rich, composed of sandy gravels and gravelly sand (so called depending on their proportions). It doesn't seem totally clear that there is a neat division of one terrace being comprised solely one kind of gravel; according to local sources the plateau of Beychevelle is comprised of Günzian gravel and the plateau of Saint-Julien of Mindel (like Pauillac), though both together form Terrace 4. The general trend is to see gravel of shallower depth as one moves westward in the appellation, but there are exceptions, such as at Château Gruaud-Larose. The eastern, southern, and southwestern edges of the more-western Terrace 3 are also hugged by older, deeper soil types at lower altitudes as one comes down off the higher plateaus – these are composed of Molasse du Fronsadais (a particular soft limestone) and clay/limestone. The iron-rich sandstone subsoil, alios, is also found in the vineyards of Château Talbot.
To the west of Saint-Julien, there are still patches of Terrace 3 and Grands Crus Classés of the Haut-Médoc indeed sit on them – but the terroir is different and less regular. To the east of the vineyard land – between the easternmost reaches of vineyard and the Gironde – is a wet, grassy area referred to as the palus or palu; it is too wet for vine cultivation here and it floods regularly. This area can become rather dramatically waterlogged; Lilian Barton Sartorius recounts a story about the palus flooding, prompting the need to rescue grazing cattle that were up to their necks in water! Immediately to the south of Beychevelle and Branaire-Ducru (which delimit the southern border of Saint-Julien), there is a broad stretch of palus that separates the Saint-Julien AOC from the next village of Cussac.
Most of the Médoc was once as swampy as the palus can be today. The peninsula was drained by Dutch engineers in the 17th century, increasing the amount of arable terroir dramatically. The land that was uncovered was understood from the outset to be of fine quality, particularly for the quality of the wine it would produce. The rapid expansion of vineyard sites producing subtly different wines inspired a kind of 'vine frenzy', with planting increasing rapidly throughout the last part of the 17th century. The drainage ditches (jalles) can still be seen today, augmented by numerous fosses (more recently dug drainage ditches), which keep the Médoc relatively dry. The Jalle de Juillac – its name a charming portmanteau of 'Julien' and 'Pauillac' – demarcates the northern boundary of Saint-Julien where it meets Pauillac, and the Jalle du Nord runs along the appellation's southern boundary.
By this point, it may seem clear why blind tasting with a goal of determining a Médoc's village of origin can be difficult, if not outright folly. One AOC, yet two different terraces which extend to neighboring AOCs, with some properties in Saint-Julien overlapping or sitting between the two terraces. My goodness. Nevertheless, Saint-Julien still somehow manages to convey a character of equilibrium, borrowing some of the power of Pauillac and some of the elegance of the better Margaux properties, to create what could reasonably be perceived as an archetype of Bordeaux. Even more meaningful than the character of the appellation as a whole is the individual character of each of Saint-Julien's Grands Crus Classés, their complexity reflecting the geologic complexity of their origin. They are great personalities in the wine world. So, open a bottle of Saint-Julien, pour a glass, and enjoy the long tour.
Later in the book, Bouffard turns from the physical foundations of Saint-Julien to the intellectual and human ones — tracing a tradition of scientific curiosity and open-minded innovation that he argues has always set Bordeaux apart.
A tradition of innovation
One last point is crucial to recognise. Michael Georges at Léoville Las Cases recounted a quote of Emile Peynaud's: 'innovation is Bordeaux's tradition'. So, we must look to the past and to the future simultaneously. Tradition is sometimes right, sometimes wrong. We should learn when to stick with it and when to depart from it. To address new challenges, we should accept the need to test new ideas – even if sometimes we don't like the results and revert to the way things were done. In this regard, Bordeaux has perhaps always led the wine world.
Consider Peynaud's own work with Ribéreau-Gayon in understanding the malolactic fermentation. After clarifying that there actually was a second fermentation, it was a struggle to convince many winemakers that malolactic fermentation was a good thing for red Bordeaux! This is long forgotten. Now everyone simply does it for red wines; with malic acid converted to softer lactic acid, harmony is improved, and the drinking window is broadened.
When Peynaud was brought in to consult at Léoville Las Cases in 1959, the property sometimes suffered from stuck fermentations, which Professor Peynaud found was to be the result of fermentation temperatures soaring into the 30s Celsius – so hot that the yeasts were killed before they could complete the fermentation. Whereas ice was previously added to the vats to prevent this problem (famously across Bordeaux in 1947), Peynaud counseled careful temperature monitoring and the withdrawal of a portion of wine from the vat to allow it to cool when the must became too hot. At the same time, Las Cases dealt (perhaps paradoxically) with extraction difficulties. Peynaud increased the overall vatting time essentially to the duration it sees today. The wine made first year he consulted – 1959 – was in my opinion a clear step up at the property thanks to these fundamental innovations.
Peynaud was carrying on the legacy of scientific observation and enquiry that had brought Bordeaux through its darkest days in the 19th century. Bordeaux led the way in grafting French vines onto American rootstock to combat phylloxera. In the same era, a cadre of individuals recognized the anti-fungal property of copper. Bouillie Bordelaise – a mix of copper sulfate and quicklime, effective against both downy mildew and powdery mildew (oïdium) – was developed in 1878, forever changing the world of organic farming as a result.
The legacy of innovation continues today. It is often assumed that innovation means more technology will be used in winemaking, but many times the opposite is the case. Léoville Las Cases has the largest private oenological laboratory in Bordeaux (perhaps anywhere) and Lagrange and Ducru-Beaucaillou are also particularly innovative places. Cornelis van Leeuwen at the University of Bordeaux has been mentioned far too few times in this book given his important work in helping to understand the science of terroir and of the vine. Despite the research that has been done over the past couple of decades, we have not seen more gadgets but rather fewer. We have seen a better understood and more balanced ecosystem, fewer synthetic interventions, and a lighter touch in the winery and barrel cellar. What we're seeing now is the application of scientific principle to study every decision, and that approach has brought people closer to their terroir and to their vines – not farther from them.
Bordeaux is well suited to lead the way in adapting to climate change and Saint-Julien is playing a key role here. Some very hot and sunny growing seasons of the distant past produced ripe wines of only moderate alcohol (the perfectly sun-kissed 1949s, for example). The reasons for this are multifactorial – vineyard health, vine material, canopy heights, picking dates, and vinification choices all likely played a role. Understanding how certain outcomes were reached is helpful; the goal is not to be reactionary, but rather to learn lessons that might be useful today. So much of that wisdom has been lost, and one of the goals of this book is to preserve it for the future.
