Domaine Oratoire Saint Martin produces wines from Cairanne, a village appellation in the Southern Rhône known for structured reds and aromatic whites. The domaine's portfolio centers on the region's classic varieties: Grenache and Mourvèdre for red wines, Viognier, Roussanne, and Marsanne for whites. Les Douyes Cairanne, a Mourvèdre and Grenache blend, represents the domaine's approach to red winemaking, while Haut-Coustias Cairanne Blanc showcases the white varieties typical of the Southern Rhône. The Cuvée Prestige Cairanne, built on Grenache and Mourvèdre, rounds out the core range. These wines have been assessed by Decanter, Wine Advocate, Wine Spectator, Wine Enthusiast, and Falstaff.
