Château Signac produces wines from Chusclan, a distinguished sector of Côtes-du-Rhône-Villages in the Rhone Valley. The winery's portfolio centers on Grenache, Syrah, and Carignan—varieties that thrive in the region's warm, sun-exposed terroir. Cuvée Dame Blanche and Le Secret, both bottled at the Villages level, blend these grapes into structured reds that have drawn attention from Wine Advocate, Wine Enthusiast, and Wine Spectator. Cuvée Terra Amata, a Syrah-Grenache blend, rounds out the core range. These wines reflect the Rhone's tradition of Grenache-led blends with the peppery depth that Syrah brings to the southern valley's reds.
