Pierre Graffeuille et Matthieu Dumarcher produces wine under the Vin de France designation, working outside the constraints of France's traditional appellation system. This freedom allows for unconventional blending across regions and varietals. The winery's flagship wine, Odyssée, combines Cabernet Sauvignon, Shiraz, Mourvèdre, Petit Verdot, and Grenache into a structured red that draws on the richness of southern French grape traditions. Decanter has rated the wine at 93.3 points, recognizing the precision of its composition. The blend's architecture—anchored by Cabernet and Syrah with supporting notes of Mourvèdre and Petit Verdot, brightened by Grenache—speaks to a winemaking approach that values balance and complexity over single-varietal purity.
