Excellent! Żubrówka is my favorite, but there aren't too many types of Polish vodkas to chose from in US stores.
There are many PL vodkas in the US...where I am anyway :)
Chopin, Belevedere, Wybrowka, Alchemy, Harnas, Jazz (comes in the shape of a trumpet), Sniper..lol looks like an AK :), sobieski..more
Where in the US are you?
I don't know how true that is for the zubrowka..it's just a wiki. I'm not sure if neutralizing the grass would even take the flavor out. I'll tell you what. I have a bottle that I just brought back from PL and I'll go to the liquor store and buy one here to see if there's a difference. Keep in mind that there are a couple different bottles of zubrowka.
