Behind the scenes
In the real world, Château Cissac wine is made in the Bordeaux wine region of France, specifically in the Haut-Médoc 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".
