Domaine de la Janasse produces wines from Côtes-du-Rhône in the Southern Rhône Valley. The winery's portfolio centers on Châteauneuf-du-Pape, the region's most prestigious appellation. Its Châteauneuf-du-Pape Prestige, built on Roussanne, demonstrates the white wine potential of this traditionally red-focused terroir. The Châteauneuf-du-Pape Chaupin blends Mourvèdre, Syrah, and Grenache—a composition that captures the Southern Rhône's signature dark fruit intensity and structure. The Châteauneuf-du-Pape Vieilles Vignes, made from old-vine Grenache, expresses the depth and complexity that mature vines bring to the appellation's signature variety. These wines have been assessed by major critics including Wine Spectator, Wine Advocate, Decanter, Wine Enthusiast, and Falstaff. The winery's focus on Châteauneuf-du-Pape reflects the Southern Rhône's commitment to bold, age-worthy reds and the occasional white of substance.
