The vodka flavored with bison grass is called Zubrovka. It is very popular in eastern and western Europe. It was illegal for some time in the US, due to a carcinogen in the bison grass. A Russian and a Polish version have been allowed to be imported again in the last couple of years.......sans the grass, but with the same flavor. I used to get the bison grass at a natural foods store in Berkeley before the ban and made my own version using a moderate priced vodka. Remember the Zubrovka scene in Maugham's "The Razor's Edge" (book and movie)?? Zubrowka Bison Grass Vodka is available in Ontario through the LCBO. They carry bison grass vodka by two different producers - Bak's and Fabryka Wodek Gdanskich. If I remember correctly, the bottles do have a couple of blades of grass in them, but I've never tried it, so I can't say for sure. Here's what the LCBO website has to say about it... "... absolute purity; the opening nosing presents a delightfully sweet and, well, grassy aroma that's more candy-like than fresh mown lawn-like -- with aeration, the aroma turns into a full-blown bouquet that's delicate yet assertive, nuanced yet perfumey in a floral way ... an intensely aromatic bouquet that's sweet in a floral manner, then the flavour expands in mid-palate to include atypical vodka tastes of cocoa, dark caramel and nougat. Score -- **** (out of 5). (F. Paul Pacult, Spirit Journal, June 1999)"
