World Calvados Day was launched by a planet-positive brand Avallen Calvados on October 20 in 2020, to celebrate the apple brandy from Normandy. 

Why October 20? Well, first of all, it’s right before National Apple Day (celebrated on October 21) and second of all, autumn is the most important season for Calvados production. Apples (and pears) are harvested, juiced and turned into a deliciously applelicious brandy.
