Cognac is a wine brandy produced in France in a delimited region centered around Cognac, encompassing a large part of Charente, almost all of Charente-Maritime, and a few enclaves in Dordogne and Deux-Sèvres. To obtain the "cognac" appellation, it must comply with very precise production standards and rules. The skills involved in making cognac have been listed as part of France's intangible cultural heritage since 2020.

Distillation is carried out according to the principle of discontinuous distillation, known as repasse or double distillation. Only eaux-de-vie obtained by double distillation of wines from the current campaign are entitled to the "Cognac" appellation d'origine contrôlée.

The origin and authenticity of cognacs are guaranteed and specified in the Cognac Appellation d'Origine Contrôlée (AOC) specifications.
