based on chren (horseradish). Called "chrenovuha". I bet Poles have something similar... :)
I never heard (or tasted) anything like that, but I live in central Poland, so it may exist in some other regions.
Anyway, the most interesting alcoholic beverages were those used during the 80's:
- denaturat (denatured alcohol) with skulls and crossbones on the label, some people used to filter it through bread and drink.
- woda brzozowa (an extract of birch and acorus leaves on rectified spirit) used in theory
against dandruff, but also a substitute, cheap alcohol for heavy drinkers.
