Kirsch is not actually a liqueur (as often thought) but a stone fruit brandy.

It can be produced using a variety of ingredients including cherries, prunes or plums. Slivovitz is comparable.

The crushed kernels of the fruit are included with the fruit juice before fermentation as they infuse the brandy with a fine, bitter tang. Baitz Kirsch is bottled for sale at high alcoholic strength (32% alc./vol.) and is unsweetened.
