Champagne received official French Appellation d’Origine Contrôlée status in 1936.
AOC status legally defines the conditions under which wine may use the Champagne name. These conditions cover the geographical area, permitted grapes, vineyard practices, yields, production methods, and maturation requirements. The designation protects the regional identity rather than merely describing a style of sparkling wine.
Champagne’s legal protection developed through several earlier measures, including efforts to define the production zone and prevent misleading use of the name. The 1936 AOC recognition belongs to the modern French appellation system created in the twentieth century.
A sparkling wine made elsewhere cannot legally be called Champagne in the European Union, even if it uses the same grapes or traditional bottle fermentation. “Champagne” therefore identifies both a place and a regulated regional product.
