Å»ubrÃ³wka, the â€œBisonâ€ brand vodka, has been produced in Poland for more than fifty years. Since 1999, â€œPolmosâ€ BiaÅ‚ystok has become the sole manufacturer of this unique and very aromatic dry vodka. It is prepared from a base of distilled luxury spirit and a tincture of bison grass, which grows only in the nearby BiaÅ‚owieÅ¼a Primeval Forest. Its particular feature is a blade of bison grass placed in every bottle. Serve straight up, or mixed with apple juice.
