Hah it's not a duty, but a pleasure to mention about it

Well, żubrówka is a species of grass, perennial. However, european bisons do not feed on it. Still, it's quite important one - its blade is added to each bottle of Vodka Zubrowka. This is one of most popular vodka in my country, and quite cheap, considering its quality

It is said that it tastes best with apple juice, yet I can't say as I've never tried it. I'm curious if it's known in your parts guys?
