Domaine de Châteaumar produces wines from the Southern Rhône, where Mediterranean warmth and ancient soils shape bold, fruit-driven expressions. The winery's portfolio centers on the region's classic varieties: Grenache, Syrah, and Mourvèdre. Secret de Nos Vignes, their Châteauneuf-du-Pape, blends Syrah, Mourvèdre, and Grenache into a structured wine that has drawn attention from Wine Spectator, Wine Enthusiast, and Wine Advocate. At the Côtes du Rhône level, Cuvée Vincent Sélection showcases pure Syrah, while Cuvée Bastien Grenache isolates that variety's peppery, mineral character. These wines reflect the Southern Rhône's signature style: ripe dark fruit, spice, and the textural grip that defines the region's best expressions.
