A kirschwasser (/ˈkɪərʃvɑːsər/ KEERSH-vahs-ər; German: [ˈkɪɐ̯ʃvasɐ], German for "cherry water") or kirsch is a clear, colorless fruit brandy traditionally made from double distillation of morello cherries, a dark-colored cultivar of the sour cherry. However, it is now also made from other kinds of cherries. The cherries are fermented completely, including their stones. Unlike cherry liqueurs and cherry brandies, kirschwasser is not sweet.
The best kirschwassers have a refined taste with subtle flavors of cherry and a slight bitter-almond taste that derives from the stones.
