Fontaine du Clos produces wines from Vacqueyras, a distinguished appellation in the Southern Rhône Valley. The winery's portfolio centers on the region's classic varieties: Grenache and Syrah for red wines, with Grenache Blanc, Roussanne, and Marsanne for whites. Pince Lapin Vacqueyras, a Syrah and Grenache blend, represents the winery's red wine expression, while Castillon Vacqueyras offers a similar varietal pairing. On the white side, Castillon Vacqueyras Blanc combines Grenache Blanc with Roussanne and Marsanne—a traditional Southern Rhône approach that captures the region's mineral and aromatic character. The wines have been assessed by Wine Advocate, Decanter, Wine Enthusiast, Wine Spectator, and Falstaff.
