Behind the scenes
In the real world, Château Cissac wine is made in the region of France, specifically in the  appellation, and not here. Nevertheless, the bottle Nicolas is holding, once you get a sharp shot of it on the table, unmistakably says both "Chateau Cissac" and "Appellation Corbières Contrôlée".
