Gold Winner, The Vodka Masters 2008. The roots of the Zubrowka Bison Grass Vodka story reach to the Bialowieza Forest, located in the remote and mysterious land of North East Poland. Here grows the precious Bison grass, the natural ingredient so unique to Zubrowka. Here also roam the rare and protected Bison from which Zubrowka takes its name. Bison grass is picked by hand at the height of summer, carefully dried and then added as an extract to a luxury rye spirit, distilled in the time honoured way at the Bialystok distillery. Zubrowka Bison Grass Vodka can only be produced in Poland at the Bialystok distillery. Floral, herbaceous, vanilla and spring flowers are just a few of the many descriptions for Zubrowka.
