Domaine des Cassagnoles sits in Côtes de Gascogne, the southwesternmost corner of France's Vin de Pays du Comté Tolosan. The region's warm continental climate and sandy soils favor white wines of clarity and minerality. The domaine works primarily with Gros Manseng, a local variety prized for its balance of weight and acidity. Its Gros Manseng bottling and Reserve Selection Cuvée Gros Manseng both demonstrate the grape's capacity for structure and complexity. A Côtes de Gascogne blend of Ugni Blanc and Colombard rounds the portfolio—a traditional pairing that captures the region's lean, refreshing character. Wine Spectator and Wine Advocate have both assessed the winery's output.
