i. Biography
Since 2017, Jean-Marc Domme has been winemaker and technical director at Château Marjosse in Grézillac, France. The work there is built on patience, parcel-by-parcel attention, and separate vinification that lets each part of the estate stand on its own. Limited-quantity micro-cuvées from the most notable plots extend that logic: small lots, handled with restraint, to keep nuance intact.
The Path
Bordeaux Sciences Agro gave Jean-Marc Domme the technical base for a career centered on precision and terroir. That training shows up in a cellar and vineyard method that stays close to parcel character, with each decision shaped by structure, observation, and the specifics of the ground. From 2020, he has worked as oenologist at Château Marjosse in Bordeaux, bringing that technical discipline into the estate’s wines. The role sits inside the same larger framework: preserve identity, work carefully, and use the cellar to sharpen what the vineyard already gives.
The Work Today
At the Grézillac estate, winemaking and technical direction sit together in Jean-Marc Domme’s role. That combination links vineyard expression to cellar execution, with the parcel remaining the basic unit of work rather than the estate being treated as one uniform source. At Château Marjosse, the method is separation, selection, and timing. Distinct plots are kept apart instead of blended into one voice, so each can contribute its own character to the final wine. The practice is measured and exact, with clarity and fidelity to place as the governing aim.
Signature
Gros Bec is among Jean-Marc Domme’s signature wines. It reflects the same parcel-level discipline that shapes the broader work at Château Marjosse: restrained handling, clear sourcing, and a preference for specificity over generalization.
Acclaim
The micro-cuvées define the recognition attached to this work: small-quantity wines drawn from the estate’s most notable plots and vinified separately to protect their differences. The distinction comes from the method itself—careful parcel separation, limited scale, and a refusal to smooth rare material into something broad and anonymous.
