Crous St Martin works the Southern Rhône's sun-baked terroirs, drawing from Châteauneuf-du-Pape and surrounding appellations. The winery's portfolio centers on Grenache-based blends—the region's signature—anchored by Syrah and Mourvedre for structure and depth. Gigondas Les Espaliers, a Syrah-Mourvedre-Grenache blend, leads the range, followed by the Grenache-forward Les Garde-Corps from Rasteau and the polyphonic Cairanne 'Les Goupilles,' which layers Syrah, Carignan, Mourvedre, and Grenache into a complex whole. These wines have been assessed by Wine Enthusiast, Wine Advocate, Wine Spectator, Falstaff, and Decanter. The Southern Rhône's warm, dry climate and rocky soils shape wines of ripe fruit and spice—the character that defines this corner of the Rhône Valley.
