What is the minimum aging requirement for Calvados?

The correct answer regarding the minimum aging requirement for Calvados is indeed two years in oak. Calvados is an apple brandy from the Normandy region of France, and its production is regulated to ensure quality and authenticity. According to the regulations, Calvados must be aged in wooden casks for a minimum of two years before it can be legally labeled as such. This aging process allows the spirit to develop its flavors and aromas, taking on characteristics from the wood of the barrels, which enhances its complexity.

The other options present aging periods that exceed the minimum requirement. While longer aging can lead to more refined and nuanced flavors, the legal standard for Calvados is specifically set at two years. Thus, it is essential for those studying beverage regulations to understand this requirement as it reflects not only the quality assurance practices in production but also compliance with regional laws governing the classification of spirits.
