Food / What is your favorite Polish Vodka? [653]

[Moved from]: Polish liquor ('wódka korzenna')

My friend once brought a bottle of Polish liquor. She said it's vodka. The label on the bottle said something like "korzana". The drink was strong and sweet, amber in colour and had anise flavor. I was not able to trace thus far, never saw it in the stores. Maybe someone can give me some prompts.
