Zubrowka...A rye based vodka made only at the POLMOS BIALYSTOK distillery in Poland. This is the real stuff , not sold in the U.S. due to the massive amounts of coumarin contained in the single blade of Bison Grass floating in the bottle. Lots of fakes on the market , so beware. This Polish vodka has been around 400 years and is a legend in Poland. Lots of reviews of Zubrowka around,some claim to taste menthol , some taste vanilla or wood.I taste only a very slightly herbal , mild , mellowness over the alcohol flavor,it really smooths it out.No "green grass" type of flavor at all, but maybe a slight "golden hay" taste ( ??? ) I drank mine chilled and neat ,I wanted the full flavor.Many Poles drink it with "cloudy" apple juice ,which I believe in America would be "unfiltered" apple juice.A gift from my good pal Vlad, I am very greatful ! http://www.eater.com/drinks/2015/11/3/9660102/bison-grass-vodka-Zubrowka
