Calvados is a French apple brandy from the French region of Basse-Normandie. It is made from specially grown & selected apples of which there are 200 varieties. A combination of sweet, tart and inedible bitter apples are used to get the right balance of flavour. These are then harvested, pressed into a juice and fermented into a dry cider which is then distilled into an eau de vie. To be classed as a Calvados this must then be aged in oak casks for a minimum of 2 years. The aging process usually lasts longer than this as the longer the process the smoother the drink becomes.
