Whatever Webster might say,
Schnapps is spelled Schnaps in Germany.
Schnaps - in Germany - is a generic term for mostly clear, high-proof alcoholic drinks. Most of the classical kinds of Schnaps are distilled from berries and certain fruit (i.e. cherries).
Schnaps is predominantly found in the south of Germany and in Austria. The french equivalent to Schnaps is eau de vie. Similar drinks exist in former Yugoslavia, Poland and the Czech Republic. Schnapsdrossel is a slang term for an alcoholic.
