Domaine de Couron produces wines from Côtes-du-Rhône, the Southern Rhône's expansive appellation known for warm-climate reds built on Grenache, Syrah, and Mourvèdre. The winery's Côtes du Rhône Villages blend—its highest-rated offering—draws from these three varieties to create the structured, fruit-forward character typical of the region's best expressions. A standard Côtes du Rhône follows, anchored by Mourvèdre and Syrah with Grenache support. Beyond the classic Southern Rhône framework, Domaine de Couron also works with Marselan, a crossing grape, in an Ardèche red that sits at the appellation's experimental edge. The portfolio has been assessed by Wine Enthusiast, Wine Spectator, Wine Advocate, and Falstaff.
