Château d'Or et de Gueules produces wines from the Rhone Valley, drawing on the region's classic Mediterranean varietals. The winery's portfolio centers on rosé expressions that blend Mourvedre, Syrah, and Grenache—grapes that thrive in the Rhone's warm climate and stony soils. Trassegum Rosé, a Mourvedre and Syrah blend, leads the range. Cuvée Gueules layers Syrah, Mourvedre, and Grenache into a more complex frame, while Les Cimels Rosé adds Cinsault to the mix, broadening the aromatic profile. These wines have been assessed by Wine Advocate, Decanter, Wine Spectator, and Wine Enthusiast. The house demonstrates a clear commitment to the dry rosé tradition of southern France, where these varietals achieve both structure and freshness.
