Famille Chéty Since 1698Atmosphère by Château Mercier, no added sulfitesSulfur is one of the antioxidants in wine, naturally occurring in grapes.
Not adding sulfites, forces us to always control the atmosphere around the juice of
grapes and then the wine. For example, inerting tanks and pipes using CO2
gas naturally produced by fermentation. From this process came the idea
to call this wine "Atmosphère".
