Domaine de Marcoux produces wines from Châteauneuf-du-Pape and the broader Southern Rhône, a region defined by warm Mediterranean conditions and ancient, complex soils. The winery's portfolio centers on Garnacha and Syrah-based reds characteristic of the appellation's bold, structured style. The Châteauneuf-du-Pape Vieilles Vignes, built from old-vine Garnacha, represents the estate's core expression—a wine that has drawn attention from Wine Spectator, Wine Advocate, Decanter, Wine Enthusiast, and Falstaff. The La Lorentine Lirac, a Syrah, Grenache, and Mourvèdre blend, extends the range into the neighboring Lirac appellation. A white offering, the Châteauneuf-du-Pape Blanc, made from Bourboulenc, rounds out the range with the mineral, herbal character typical of Southern Rhône whites. These wines reflect the terroir and varietal traditions of one of France's most storied red wine regions.
