Gilles Troullier produces wines from Côtes Catalanes, a subregion of Pays d'Oc in southern France known for its Mediterranean climate and diverse terroir. The winery's portfolio centers on indigenous and regional varieties suited to the warm, dry conditions of Catalonia. L'Esprit du Temps, a Grenache wine, represents the core of the range and has earned recognition from Wine Advocate and Wine Spectator. Le Pas del Gazeil, made from Lledoner Pelut—a rare Catalan variety—offers a distinctive expression of local character. The winery also produces L'Imprévue Pet Nat, a sparkling wine blending Grenache Gris and Grenache Blanc, capturing the aromatic potential of white Grenache varieties in a lighter, effervescent form. These wines reflect the winery's focus on Grenache in its multiple expressions, a grape that thrives in the Côtes Catalanes and yields wines with depth and regional authenticity.
