Plum brandy by John Spottiswood.

Distilled from plums, plum brandy is usually colorless and quite potent. Slivovitz = slivovic = slivowitz ( SHLIV-uh-vits) is made in Serbia and Bosnia from blue plums, and is very highly regarded. Other varieties include mirabelle (made with yellow plums), quetsch (Alsatian plums), pflümli, and light green prunelle.
