Since the 13th century, the vokka has been heralded for its supposed aphrodisiac and virility-inducing qualities. Until the 1970s, bison grass vodka was banned from the US because of its reputation as a medicinal drink. Hey, I didn't say it, but I know you're thinking it - hallucinatory? mind-altering?
I tried zubrowka for the first time at a Polish restaurant in Santa Monica, Warszawa. The server poured the clear, though slightly ivory-tinted lquid into a shot glass and said I should try it straight to really taste the difference from regular vodka. It had a very distinctive taste - something like a slightly sweet vanilla mixed with herb - though the flavor wasn't overpowering. It was pretty tasty, and certainly much nicer to drink straight vodka that had a little bit of flavor to it than say, straight Belvedere.
More recently, I tried zubrowka in a cocktail at a vodka lounge. The bartender mixed the bison grass vodka with apple juice, which seems to be a fairly common mixer for the stuff. I didn't like it at all - it tasted like alcoholic herbal apple juice. I'd rather have bison grass vodka straight.
Both occcasions, I did not notice either the aphrodisiac or virility properties of the vodka. Oh well.
