"Calvados is distilled from specially grown and selected apples, of which there are over 200 named varieties. It is not uncommon for a Calvados producer to use over 100 specific varieties of apples, which are either sweet, tart, or bitter, with the latter category of apple being inedible. The fruit is picked (usually by hand) and pressed into a juice that is fermented into a dry cider. It is then distilled into eau de vie. After two years aging in oak casks, it can be sold as Calvados. The longer it is aged, the smoother the drink becomes."
