Château de Flaugergues produces red wines from Languedoc, the sprawling southern French region known for robust, sun-ripened blends. The winery's portfolio centers on Rhône varieties—Syrah, Grenache, and Mourvèdre—combined in different proportions across its range. Cuvée Colbert and La Sommelière Rouge, both built from these three grapes, represent the core of the estate's output and have drawn assessment from Wine Spectator, Wine Advocate, Decanter, and Wine Enthusiast. Les Galets Grès de Montpellier, a Mourvèdre-led blend, rounds out the lineup. These wines reflect Languedoc's warm continental climate and limestone-rich soils, which favor the ripeness and structure these southern Rhône varieties demand. The winery's approach emphasizes the interplay of these classic Mediterranean grapes rather than single-varietal expression.
