Domaine du Bois de Saint Jean operates in the Southern Rhône, where Mediterranean warmth and ancient soils shape wines of depth and character. The domaine works with the region's signature varieties: Viognier, Syrah, and Grenache. Madame d'Ust Côtes du Rhône, a Viognier-based expression, demonstrates the white wine potential of the appellation with aromatic intensity and mineral precision. La Ballade des Anglès Vacqueyras, a Syrah and Grenache blend, captures the darker, more structured side of Southern Rhône red winemaking—a wine of substance built on the region's warm-climate fruit and tannin architecture. Gadagne Côtes du Rhône Villages, a pure Syrah, rounds out the portfolio with the peppery, savory character typical of the grape in this terroir. The wines have been assessed by Wine Spectator, Decanter, Wine Advocate, Wine Enthusiast, and Falstaff.
