Le Mas des Collines produces wines from the Southern Rhône, where Grenache and Syrah thrive in the region's warm, wind-swept terroir. The winery's Gigondas—a blend of Grenache and Shiraz—captures the intensity and structure characteristic of the appellation's best expressions. A Côtes du Rhône, built on Syrah and Grenache, offers a more approachable entry point to Southern Rhône character. Both wines have been assessed by major critics including Wine Spectator, Wine Advocate, Wine Enthusiast, and Decanter, reflecting the winery's standing within the region's quality conversation.
