Kirschwasser (pronounce [ˈkɪɐ̯ʃˌvasɐ]), German for "cherry water", often known simply as Kirsch (from German "Kirsche" for "cherry") in the English-speaking world, is a clear brandy made from double distillation of the fermented juice of a small black cherry. It is colorless because either it is not aged in wood or it is aged in barrels made of ash. The cherries used recently can be either sweet or sour, but in the past the sour morello cherry was used with the stone crushed and included. As the morello cherry was originally grown all around the Black Forest in southern Germany, the drink is believed to have originated there.
