Domaine de Saint Siffrein operates in the Southern Rhône, where the region's warm continental climate and distinctive terroir shape wines of depth and structure. The domaine works with the classic varieties of the appellation: Syrah, Grenache, and Mourvèdre—grapes that thrive in this sun-exposed landscape. Au Bord du Chemin, a blend of Syrah, Grenache, and Mourvèdre, represents the domaine's approach to red winemaking, as does Terre d'Abel Châteauneuf-du-Pape, which emphasizes the same trio of varieties. The domaine also produces Châteauneuf-du-Pape Blanc from Bourboulenc, capturing the mineral and aromatic character possible in Southern Rhône whites. Wines from Domaine de Saint Siffrein have been assessed by Wine Enthusiast, Decanter, Wine Advocate, Wine Spectator, and Falstaff.
