Which of the following is NOT one of the crus of Cognac?

The term "crus" refers to the designated growing areas or terroirs within the Cognac region of France, which are classified based on their specific qualities and characteristics. Grande Champagne, Petite Champagne, and Fins Bois are all recognized crus of Cognac. Each cru has its own unique soil types, climate conditions, and grape varieties that influence the flavor profiles of the Cognac produced in those areas.

Grande Champagne is known for producing the most prestigious Cognacs, characterized by finesse and complexity. Petite Champagne also produces high-quality Cognacs, though typically they are considered a step below those from Grande Champagne. Fins Bois, while producing robust and fruit-forward Cognacs, is geographically larger and often yields spirits that mature more quickly than those from the first two crus.

The term "Grand Cru," however, is not applicable in the context of Cognac crus. "Grand Cru" is commonly associated with wine terminology, particularly in regions such as Bordeaux and Burgundy, where it denotes a vineyard or estate of high quality. In the Cognac classification, there is no designation of "Grand Cru," making it the correct answer to the question.
