His philosophy

Questioning, audacious, groundbreaking.

We're all entrepreneurs. The winemakers for whom we work and the consultants at Oenoteam. Being entrepreneurs means giving our all to a project and grouping together to achieve a common goal. It's about transmitting knowledge and passion in a durable way. It's about trusting yourself and each other, and always respecting peoples' differences. Strong relationships are an absolute necessity for success.

His clients

I can express myself through 19 grape varieties of every colour, through organic, biodynamic and conventional agricultural techniques, through famous estates or little-known ones. In each case, beyond the human, technical and financial aspects, the objective is to position or consolidate the estate within its own environment - in terms of its geography, competitors, management systems - whilst taking into account its DNA and its people. Every estate deserves the equal attention and commitment, so that's my common denominator.

I am sharing with you my vision for three properties for each of which my involvement has had an obvious and different kind of impact. These are wines that have found their place, their balance and their identity in a global sense.

Confidence and trust
Château Haut-Veyrac

Saint-Emilion Grand Cru

Owner: Guillaume Claverie
Surface area: 10 hectares
Number of wines: 1 (AOC Saint-Emilion Grand Cru)
Consultant Oenologist: Julien Belle since 2013

Here, we bring together technical work and modernity with expressiveness and aromatic clarity. To achieve this we first had to get to know each other. To exchange and identify the unique character of each plot of vines, avoiding the easy option that a property with all its vines in a single block allows. Our aim is to produce an excellent wine that everyone can access.

Trust is our keyword. Each member of the Haut-Veyrac staff, from the vineyard team to the wine tourism team and the owners is regularly consulted. Each person has a voice and reflects the multi-facetted environment in which the property is evolving today. We listen to consumers and work with trust to bring out the diversity of a singular property.

Creating a signature
Château du Bousquet

Côtes de Bourg

Owner: Vignobles Castel
Surface area: 65 hectares
Number of wines: 1 (Côtes de Bourg Red AOC)
Consultant Oenologist: Julien Belle since 2014

Here are 65 hectares of incredibly diverse terroir. Collaborating with Antoine de Oliviera, Technical Director, we have established a relationship of trust with a real human dimension. We concentrate on the core identity of Château du Bousquet, adjusting and fine-tuning our goals vintage after vintage, and respecting the unique character of Côtes de Bourg. It is crucial to reveal its distinctive characteristics: expressive aromatics and precise tannins. The blending and ageing processes therefore require constant, rigorous work. The château is already a reference for quality in Côtes de Bourg, and my job is to reinforce the signature style given by the estate’s very particular terroir.

A grand restoration
Château de Cérons


Owners: Xavier and Caroline Perommat
Surface area: 26 hectares
Number of wines: 3 (2 Graves Red AOC, 2 Graves Dry White AOC, 1 Cérons AOC)
Consultant Oenologist: Julien Belle since 2008

This adventure begins in some of Bordeaux’s most historic but lesser-known vineyards, which are staunchly defended by many in the winemaking profession. Since 2008, I have accompanied Xavier and Caroline Perromat (from Haut Bailly) through a family transition that began in 2012 as they embarked on a new adventure to restore this noble property to its former glory. The wines are emblematic, with something of a Chablis or Sancerre touch to them, but with Graves at their core and an unusual range of subtleties. This Cérons-specific character is upheld wholeheartedly by Caroline and Xavier, who manage the property with real energy and dynamism.

We spend time together, we discuss, we ask questions and we move forward with exactness. The result might be called a Cérons in the Graves, or a Graves in Cérons. Whichever way you choose to look at it, there is nothing else quite like it.

His philosophy

Respecting diversity, encouraging singularity, remaining loyal

I'm very fortunate to be among the next generation of in-the-field oenologists who are in contact with the technical teams every day. My vision and understanding of this profession have been built through teamwork at Oenoteam. Like my associates, I spend three quarters of my time at the estates but oenological analysis always supports my actions. The lab is my research center, the soil my testing ground.

His clients

I consult for a highly diverse group of Bordeaux estates, from entry-level Bordeaux to Premier Grands Crus Classés. My aim is for each property I work with to have its own identity and wines that withstand the ages with perfect integrity. Time is the silent test for Bordeaux’s finest wines, and an oenologist’s success in helping to constantly improve quality can only be judged over many years. 

I want to present three estates to you, all of which are special to me for different reasons and all with one thing in common: terroir that is treated with respect.

Respecting identity
Château Canon

Saint-Emilion Premier Grand Cru Classé B

Owner : Chanel
Surface area: 34 hectares
Number of wines: 2 (AOC Saint-Emilion)
Consultant Oenologist: Thomas Duclos since 2012

I first discovered Château Canon in 2000, while I was a student, and it was Canon that first made me want to work in this field. The property has a real sense of identity and style, and I immediately felt the need to understand how and why the wines were so special.

I work with closely with Nicolas Audebert, Estate Manager, and Stéphane Bonnasse, Technical Director. The team stands for and demands high precision in everything that we do, from fixing specific harvest dates for each plot to sorting every barrel of press-wine. Chateau Canon is as timeless and anti-conformist as its wines are balanced and delicate. I firmly believe in Canon, and am happy to be a cog in the wheel of a magnificent property whose best years still lie ahead.

Perfect balance
Château Ragon Bel-Air

Bordeaux and Bordeaux Supérieur fom Landerrouat

Owner: The Sorges family
Surface area: 300 hectares
Number of wines: Sold in bulk
Consultant Oenologist: Thomas Duclos since 2007

Here the vines are machines of production. I know the Sorges family very well and have been coming here for around 10 years. They started small 60 years ago, with just 6 hectares; today they are one of the key players in the quality Bordeaux and Bordeaux Supérieur market. Efficiency and streamlining are buzzwords and we must capitalise on everything. The Sorges have equipped the 60,000 hectolitre vat room with high-performance equipment to improve quality. The latest addition was the integration of thermo-vinification tools.

It is an estate where I strive to guarantee consistent quality and the reliability that comes with a well-made finished product, without perceptible variation between vintages. Thanks to their hard work, it’s a success.

Pomerol style
Château La Cabanne


Owner: Vignobles Jean-Pierre Estager
Surface area: 10 hectares
Number of wines: 1 (AOC Pomerol)
Consultant Oenologist: Thomas Duclos since 2012

Making wine in Pomerol is sacred. In this small appellation every terroir is pushed to express its utmost identity, and to be distinct from its closest neighbours. Here everything is about honesty; and perhaps more so than anywhere else, the vintage counts for everything. La Cabanne is in the Estager family’s DNA; over many generations, they have developed an understanding and mastery of the terroir. We must work together to become ever more precise, ensuring that the wines remain fresh and silky 30 years down the line.

Marie-Laure Badet Murat
Her philosophy and mission


In 2018, I joined Stéphane, Thomas and Julien to involve myself in an oenological project that excites us: reinforcing the link between oenological analysis and the in-the-field work by creating a state-of-the-art laboratory as a technical tool to help winemakers anticipate and make better decisions.

My attachment to the land, and years working on a thesis, led me to become passionate about analysis and orientate my career towards this domain.

Having run and developed a modern laboratory for 12 years, and driven by a desire to share my knowledge, I also became a consulting Professor at Bordeaux Sciences Agro and an expert scientist certified by the national Ministry for Education, Higher Education and Research.

My role within the team:
To provide and develop precision analytical services to support decision-making.
To work in a scientific and analytical monitoring capacity to drive improvements in the analytical tools, always with the same objective: to guide the practician in their technical choices and in their search for oenological precision.



As a group of 4 consultants, we have a strong unified vision of technical analysis: it is a decision-making tool that should form part of the relationship between wine producer, laboratory and winemaking consultant. We stand by the importance of analytical monitoring, which enables us to understand a vast range of different client-specific variables and make the right decision in every instance.

Our equipment

New investments every year ensure that we remain at the cutting edge of oenological science. All of our analytics are double-checked so as to assure accurate results. Innovation is a core focus. Thanks to a carefully chosen, wide range of equipment (much of it in duplicate to ensure that we are able to meet high demand at key moments in the winemaking cycle and to lower the risk of technical failure) we offer a wide range of services in different areas: from grapes to wine, but also vegetal material and other materials that are in contact with the wine.
