Final answer:
Cognac is a type of brandy that must come from the Cognac region of France, adhering to strict production regulations under the Appellation d'Origine Contrôlée (AOC) system to be labeled as Cognac.
Step-by-step explanation:
Cognac must come from the Cognac region of France to be rightfully called Cognac. This is a legally defined and protected appellation, meaning that only brandy produced in this specific area, following strict production methods, can be marketed under the name 'Cognac.'
The process includes specific requirements such as the types of grapes used, the distillation process, and the aging period, which must take place in oak barrels from the region.
The importance of origin in the naming of beverages can be seen in other drinks like Champagne, which similarly must come from the Champagne region of France. This exclusive naming is part of the Appellation d'Origine Contrôlée (AOC) system, which France and other European countries use to ensure quality and authenticity of traditional products.
