Bison Grass? Never heard of it. But they say you can make vodka out of almost anything and the Poles have figured out a way. I had a shot of this stuff straight and then again with a twist over ice. Normally I'd tell you vodka has no flavor, just a burning sensation. Well, I'm pleased to say this vodka did have hints of flavor, grassy as you might have expected. If you've ever chewed on a long piece of grass there is a flavor there, combine that flavor with vodka and you have Zubrowka Bison Grass Vodka. I prefered it with lemon.
Maybe I'm just not a connoisseur of vodka yet.
