Zubrowka, also known in English as Buffalo Grass Vodka or Bison Grass Vodka, is a brand of dry, herb-flavored vodka that is distilled from rye and bottled at 37.5% alcohol by volume (75 proof). Its flavour is unique and is described as having woodruff, vanilla, coconut, and almond notes. The rye distillate is flavored with a tincture of buffalo grass (Hierochloe odorata), which also gives the spirit its yellowish color. This grass grows in the Bialowieza Forest (which is partly in Poland and partly in Belarus) and elsewhere. A blade of buffalo grass is traditionally placed in each bottle of Zubrowka, though this is largely decorative. The name Zubrowka comes from zubr, the Polish, Belarusian, and Ukrainian word for the wisent (European bison), which is particularly fond of eating buffalo grass.
