Jean de Cournuaud

The Path

Study at Université Montpellier I gave Jean de Cournuaud a rigorous starting point, and the work that followed reads as a steady accumulation of practical judgment. In 2018, a technical-director role in Saint-Émilion placed him in one of Bordeaux’s most closely watched winemaking settings, marking a clear step in a career built on technical responsibility rather than display. Today, the work at Château Mazeris in Saint-Michel-de-Fronsac, France, is defined by the pairing of winemaker and vine grower. Jean de Cournuaud holds both responsibilities, which keeps vineyard and bottle in the same line of sight. That dual role says as much about the estate as it does about the person: the craft is continuous, and the decisions made in the vines carry straight through to the wine.

The Work Today

At Château Mazeris, the dual title of winemaker and vine grower keeps the job grounded in two connected disciplines. One side is agricultural, seasonal, and exacting; the other is cellar-based, shaped by timing and controlled adjustment. Jean de Cournuaud’s role asks for both, and the value of that arrangement is clarity: the fruit is not treated as separate from the wine, and the wine is not separated from the place that produced it. That continuity is the defining feature of the work. The estate is not a backdrop but the center of the operation, and Jean de Cournuaud’s position at Château Mazeris reflects a practice built around close reading of site and crop. For another artisan, the point is familiar: the craft is strongest when vineyard and cellar are treated as one conversation.
