A popular Norman legend tells that during the "Invincible Armada" in 1588, one of the ships of the Spanish fleet that crossed the English Channel sank and washed ashore on the Normandy coast. The name of this boat, the "San Salvador" was given to the rocks bordering the coast. Then over time, the word "Calvador" and then "Calvados" a term that became the name of the region in 1789 and then that of its famous apple alcohol.
It was only in 1942 that Calvados received the appellation of controlled origin (AOC), a way of preventing the Germans from requisitioning it during the occupation because they could not seize the classified alcohols.
