Bar-sur-Seine is a commune in the Aube department in the Grand Est region of north-central France.
Most Champagne vines are grown in the Marne department (on Cretaceous land) in the Marne valley (to the west of Château-Thierry) and on a series of lands straddling the Tertiary and Cretaceous (Avize, Vertus, Sézanne etc.)
Champagnes of Aube are very eccentric and very southern compared to other Champagnes and are grown on Jurassic lands which makes them distinctive. This area of Aube Champagnes includes other neighbouring communes such as Les Riceys and Bar-sur-Aube.
