Some châteaux look like all the others. And then there is Cos d'Estournel. The first time I parked in front of its famous pagodas, I understood in a second why this place has fascinated people for almost two centuries. You are not really in Saint-Estèphe. You are somewhere else.
Come with me for a full immersion at Château Cos d'Estournel, the Second Growth classified in 1855 that truly looks like no other. On the programme: a tour of the estate, the three-level gravity-flow cellar, a tasting of the 2025 vintage ahead of the Primeurs, and lunch at La Maison Estournel, the restaurant opened in 2021 by three-Michelin-star chef Jérôme Banctel. Spoiler: I did not come out of it indifferent.
The immersion in brief
- Château Cos d'Estournel, Second Growth classified in 1855, in Saint-Estèphe, in the north of the Médoc, 50 minutes from Bordeaux.
- Unique architecture with its three Asian-inspired pagodas, its Buland Darwaza door from the palace of the Sultan of Zanzibar and its two stone elephants at the entrance.
- A modern gravity-flow cellar on three levels, around sixty tapered stainless steel vats, among the most advanced in the Médoc.
- Owned by Michel Reybier Hospitality since 2000 (the group behind La Réserve Paris and La Réserve Genève).
- La Maison Estournel, a hotel and restaurant opened in 2021 in the heart of the vineyard, a bistronomic table by chef Jérôme Banctel (three Michelin stars at Le Gabriel, La Réserve Paris).
- "In the footsteps of the Maharajah" tour: 2 to 3 hours, 6 wines tasted, 750 € for 1 to 6 people.
1. Cos d'Estournel, a château like no other
Let's say it straight away: Cos d'Estournel stands apart in the Médoc landscape. When you drive up from Bordeaux and pass the long straight avenues of Pauillac, you expect another classic château with pale render and neat rows of windows. Instead, you come across pagodas. Three Asian pagodas set on the facade, as if someone had imagined an unlikely dialogue between Bordeaux and the East.
We owe this folly to one man: Louis-Gaspard d'Estournel, who began buying plots here in 1811. He was a character straight out of a novel. He traded his wines as far as Calcutta and Bombay in the 1830s, which was completely unusual for a Bordeaux château owner of the time. His travels in the East earned him the nickname "Maharajah of Saint-Estèphe". And he breathed that imagination into his château, down to the wildest detail: the Buland Darwaza door, in precious wood, comes straight from the palace of the Sultan of Zanzibar. Two stone elephants keep watch at the entrance. Truly, this is no ordinary Bordeaux château.
On the terroir side, we are back in Bordeaux. Cos is planted on an exceptional gravel and clay mound, on the border with Pauillac. The name itself says so in old Gascon: "Cos" means "hill of pebbles". Everything is there, in that tongue of gravel that drains and warms the roots, and gives cabernet sauvignon its legendary structure.
In terms of rankings, the estate was classified as a Second Growth in 1855, in the famous classification ordered by Napoleon III for the Paris Universal Exhibition. And its rank has never changed since. That is not trivial. It says something about the consistency of an estate that has known, for almost two centuries, what it has to say.
Since 2000, Cos d'Estournel has belonged to the Michel Reybier Hospitality group, which also owns La Réserve Paris, La Réserve Genève and Château La Mascaronne in Provence. That largely explains the turn taken in recent years towards the art of hospitality, which I will tell you about in the third part.
2. Inside the gravity-flow cellar, tasting the 2025 vintage
If the outside of Cos plays on flamboyance, the inside of the cellar plays on technical elegance. Opened a few years ago after a complete renovation, it is now considered one of the most advanced gravity-flow cellars in the Médoc. Three stacked levels let the grapes, then the wine, move by gravity, without ever being pumped aggressively. Some sixty tapered stainless steel vats await the harvest, plot by plot.
It was in this cellar that I was lucky enough to taste the Cos vintage ahead of the 2025 Primeurs. WSET 2 method in hand, I took my notes.
My tasting notes for Cos d'Estournel 2025
The 2025 vintage confirms the legend of years ending in 5 in the Médoc, which almost always herald great wines. The estate itself speaks of an ideal climate scenario, and you can taste it.
👀 Eye: deep, intense, almost opaque colour, with lovely purple glints on the rim.
👃🏼 Nose: remarkable aromatic complexity, dominated by bright red and black fruit (blackcurrant, blackberry, Burlat cherry), a touch of cedar and sweet spices that hints at the oak without shouting it.
👄 Palate: a powerful, structured and deeply elegant wine. Cabernet sauvignon and merlot dominate. A texture that is already silky, almost caressing. And that is the real marker of the vintage: 2025 is a Cos that can be drunk young, that can be approached today, without giving up any of its impressive ageing potential. And that is The Trend of 2025.
A grand cru that is no longer afraid of being enjoyable. That is what I took away, and believe me, that was not always the case in this category ten years ago.
3. La Maison Estournel: the table by Jérôme Banctel
And then there is La Maison Estournel. Opened in 2021 in the heart of the Cos vineyard, right in the Saint-Estèphe appellation, it extends the experience of the estate well beyond the glass. The concept is crystal clear, and it is precisely what sets it apart from the other wine tourism addresses I know in the Médoc.
A bistronomic table by a three-star chef
The kitchen at La Maison is entrusted to chef Jérôme Banctel, who holds three Michelin stars for Le Gabriel at La Réserve Paris. Here he offers modern, refined and contemporary bistronomic cooking, centred on local and seasonal produce, much of it from the estate's garden. The menu changes almost every day. What I took away: the standards of a starred chef, but without the ceremony that can sometimes weigh things down. It is precise, clear and generous.
And of course, pairing with the wines of Cos is available on request, at lunch and at dinner. It is the exercise that really makes the trip worthwhile: matching a cuvée born a few metres from your plate, in the cellar next door, with a dish built to show it off. Few wine tourism experiences in Bordeaux offer this level of coherence.
A discreet hotel in the heart of the vines
La Maison Estournel is also a luxury hotel with around twenty rooms and suites, in the spirit of a very high-end private house. An intimate atmosphere, far from the big classic palace hotels. A discreet spa, a pool, spaces opening onto the vines. To be completely transparent with you, I have not stayed there yet, so I will not talk about the overnight experience here. But the atmosphere I saw over lunch suggested that the hotel experience is very much worth the trip. I will tell you more as soon as I have tried it.
The whole place aims for one thing: a complete immersion in the world of a Grand Cru Classé, but in a contemporary, high-end version. And that is new in the Médoc landscape.
4. My practical tips for a successful visit
Now, the practical side. If you want to experience this immersion yourself, here is how I recommend going about it.
Which experience should you choose?
The château offers two main formats, by reservation only.
- "In the footsteps of the Maharajah": a 2 to 3 hour visit, the gravity-flow cellar, the vineyard and 6 wines to taste. 750 € for 1 to 6 people, then 125 € per additional person. It is the essential immersion, perfect in my view for a first visit.
- "The Treasures of the Maharajah": same length, but the tasting includes four older vintages of Cos d'Estournel. 1,800 € for 1 to 6 people, then 300 € per additional person. For enthusiasts who want to work through a vertical and understand how Cos evolves in the cellar.
How to book and get there
- Tour bookings: visite@estournel.com or +33 5 56 73 15 50.
- Address: Cos S, 33180 Saint-Estèphe.
- Allow 50 minutes by car from central Bordeaux, via the D2 (the legendary Route des Châteaux).
- If you are planning to taste, do as I did and use a private transport service. I recommend Efandji High-Ends Transports, which handles these château trips wonderfully.
When should you go?
My two favourite seasons to visit Cos are April, during the Primeurs (the buzz is unique, you taste things you will not see again for two years), and September, just before or during the harvest (the light on the pagodas at 6 pm, really, treat yourself). In summer the estate is calmer, which is also lovely for a quiet half day followed by lunch at La Maison.
Should you combine it with La Maison Estournel?
In my opinion, yes, without hesitation. A tour of the château in the morning, lunch at La Maison Estournel in the afternoon, and you leave with a complete understanding of the estate, from grape to plate. That is how I spent my day, and it is what I recommend to readers who really want to capture the spirit of the place.
My take, in a few words
Cos d'Estournel is not a château like the others. Not in its architecture, not in its history, not in the way it welcomes visitors. Where many classified growths still settle for opening their cellar to hurried groups, Cos has chosen a real immersion, polished down to the details, and now extended by an exceptional table. The 2025 vintage I tasted only confirmed my impression: this estate knows how to reinvent itself without letting go of any of its rigour. And that is rare.
➡️ So, shall we head up to Saint-Estèphe? Tell me in the comments or on Instagram if you have already visited Cos, and what stayed with you.
🙏 A huge thank you to Elio Gastaldello and the whole Cos team for the welcome, and to my partner for the day for the photos.
