De Sousa Champagne: Biodynamic Grand Cru Chardonnay From Avize
Some producers you discover slowly. De Sousa was the opposite for us. One glass of their Chardonnay, poured in a cool cellar in Avize, and we knew. It had that rare combination of precision and warmth, like a perfectly cut stone that still somehow feels alive.
This is the story of a family estate in the heart of the Côte des Blancs, why they farm the way they do, and which bottle we would open first.
A Family Estate in the Heart of Avize
De Sousa is based in Avize, one of the great Grand Cru villages of the Côte des Blancs, the long chalky slope south of Épernay where Chardonnay is king. The family farms roughly 10 hectares, most of them in some of the most respected villages in the region: Avize, Le Mesnil-sur-Oger, Cramant and Oger.
It is a family house in every sense. The estate was shaped by Erick De Sousa, a pioneer of biodynamics in Champagne who died in 2023. Today his three children, Charlotte, Julie and Valentin, run it, and every decision, from the vineyard to the cellar, is made by the family itself. Because the family farms its own vines and makes and bottles its own wine, De Sousa controls the whole chain from vine to glass.

Biodynamics, With Horses
What sets De Sousa apart is a deep commitment to biodynamic farming, long before it became fashionable. The conversion began in 1999. Organic certification followed in 2010, and full Demeter biodynamic certification in 2013.
In practice that means no synthetic chemicals in the vineyard, herbal preparations to support the life of the soil, and a farming calendar that follows natural rhythms. It also means horses. Part of the vineyard is still ploughed by horse rather than tractor, because a heavy machine compacts the soil and damages the fine network of roots and microbial life underneath.
When we walked the vineyards, the difference between a horse-ploughed row and a tractor-ploughed one was visible in the soil texture alone. Looser, darker, more alive. If you want to understand why this matters, our guide to organic champagne explains the principles.
Old Vines and Chalk
The average vine age at De Sousa sits around 45 years, which is remarkable even by Côte des Blancs standards. Old vines produce fewer grapes, but those grapes carry more concentration. Their roots go deep into the chalk, an ancient seabed compressed over millions of years, which drains perfectly and gives the wines their striking mineral freshness.
In the cellar, every parcel is vinified separately, with indigenous yeasts and manual riddling (remuage). That patience shows. Each wine carries the fingerprint of the slope it came from.
The Style: Precise, Mineral, Generous
If you are new to the style, De Sousa is a beautiful introduction to what Blanc de Blancs can be: champagne made only from Chardonnay. Expect citrus, white flowers, a chalky, almost salty edge, and a long, clean finish. But De Sousa adds something more: a ripeness and texture that come from old vines and from oak ageing for some cuvées. These are not austere champagnes. They are precise and generous at the same time.
Where to Start: Cuvée des Caudalies
If you only try one, make it the Cuvée des Caudalies. It is one of the most special bottles we stock.
A caudalie is an old French unit for measuring how long the flavour of a wine lingers after you swallow: one caudalie equals one second. The name is a promise, and the wine keeps it.
Caudalies is made from Grand Cru Chardonnay from vines more than fifty years old. The wine is vinified entirely in oak barrels, which gives it depth and a rich texture you can feel. The blend combines wine from the current harvest with a reserve the family started in 1995 and has been feeding ever since: a true perpetual reserve. The result marries freshness and maturity: delicate oak, ripe yellow fruit, and a long, precise finish.
Pour it at 9 to 11 °C rather than ice cold, in a tulip or white wine glass, and give it time in the glass. It changes with every sip.
Food With De Sousa
Chalky Grand Cru Chardonnay is a dream at the table. A few matches we love:
Oysters and scallops, raw or lightly seared
Turbot or sole with a beurre blanc
Aged Comté or a mature Beaufort
Poultry with morels and cream, for the oak-aged cuvées
Why We Chose De Sousa
We wanted a producer on our shelves who represents what biodynamic champagne can be, and De Sousa went beyond that brief. This is a family that has invested decades in farming practices most producers are only now beginning to explore. They did it out of conviction, not marketing.
That is exactly what The Champagne Fox is about: real people, real places and real choices you can taste. You will find De Sousa alongside the other families we work with in Meet Our Growers.
