Château Coussin produces wines from Provence, the Mediterranean region renowned for its dry rosés and mineral white wines. The winery's Sainte Victoire Côtes de Provence Rosé, a blend of Shiraz, Grenache, and Cinsault, achieves a pale salmon hue and the region's characteristic freshness—a wine that has drawn attention from Decanter and Wine Enthusiast. The César à Sumeire Blanc, made from Vermentino, and the Côtes de Provence Blanc, a blend of Rolle and Vermentino, showcase the aromatic, crisp character typical of Provençal whites. Both white offerings reflect the limestone soils and maritime influence that define the appellation's mineral-driven profile.
