i. Biography
Stephane Dupuch’s work is built on inheritance, but the relevant detail is what he did with it. At Château Sainte-Marie in Entre-Deux-Mers, a fifth-generation estate on 78 hectares in Targon, he took over in 1997 and moved the property to organic viticulture. That choice kept the family line intact while changing the farming behind it. On this kind of estate, continuity is not only a matter of ownership; it is also a method.
The Climb
In the regional trade, representation can sit alongside production. Stephane Dupuch held the presidency of the syndicate of wines of the Entre-Deux-Mers, a role that placed him inside the appellation’s working structure as well as within his own vineyard. The position points to the dual demands of the job: reading a site closely while speaking for a wider wine region. Today, Stephane is owner & winemaker of Château Sainte-Marie, a position he has held since 1997.
Today
Since 1997, Dupuch has run Château Sainte-Marie in Targon as both owner and winemaker. The estate is the family property he inherited from his father, and the wines come from organic farming in Entre-Deux-Mers, Bordeaux. The wines are defined by the estate’s own material conditions: Old-vine Sémillon and Merlot blends. The mix links varietal choice to vineyard age and to Bordeaux place, keeping the emphasis on what the property can produce rather than on an outside style. Under organic viticulture, the estate’s identity reads as both inherited and actively maintained. Fifth-generation continuity gives that choice added weight. At Château Sainte-Marie, the move to organic viticulture came from an inheritor working within a long family line, not from a new owner arriving on blank land. Dupuch’s career shows how a historic property can change method without losing its place in the family record.
Signature
Stephane's signature wines include Petite Marie, Vieilles Vignes, Madlys, and Alios. The names sit within the broader identity of Château Sainte-Marie, where each bottle reflects the same steady alignment of inheritance, place, and practice.
Recognition
Dupuch’s major public recognition in the provided career arc is appellation leadership: he formerly served as president of the syndicate of wines of the Entre-Deux-Mers. For a winemaker tied to a fifth-generation estate, that presidency connects private inheritance with collective Bordeaux identity. His long tenure from 1997 to present at the Targon estate is also the frame through which his work is understood. The central achievement is sustained organic viticulture at a 78-hectare family property, carried through wines associated with Entre-Deux-Mers and Old-vine Sémillon and Merlot blends.
