Marrenon produces wines from the Southern Rhône, where Grenache and Syrah define the region's character. The winery's Les Belles Échappées Gigondas blends Grenache with Syrah, drawing on the appellation's reputation for structured, fruit-forward reds. Inventa Les Vallons showcases white varieties—Grenache Blanc and Vermentino—offering the crisp, mineral-driven profile typical of Southern Rhône whites. The Grand Marrenon Rouge, built on Syrah, rounds out the portfolio. These wines have been assessed by Wine Enthusiast, Wine Spectator, Wine Advocate, Decanter, and Falstaff.
