Żubrówka [ʐuˈbrufka] ( listen), also known in English as Buffalo Grass Vodka or Bison Grass Vodka is a dry, herb-flavoured vodka that is distilled from rye and bottled at 40% alcohol by volume (80 proof). Its flavour is unique and is described as having woodruff, vanilla, coconut, and almond notes. The rye distillate is flavoured with a tincture of buffalo grass (Hierochloe odorata). This grass grows in the Białowieża Forest (which is partly in Poland and partly in Belarus) and elsewhere. A blade of buffalo grass is placed in each bottle of Żubrówka. While such piece of grass may be used mostly for decorative purposes, in mass production alcohol is infused with bulk amount of grass in order to obtain beverage's taste and yellowish color. The name Żubrówka comes from żubr, the Polish, Belarusian, and Ukrainian word for the wisent (European bison), which is particularly fond of eating buffalo grass.
Żubrówka is usually served chilled and mixed with apple juice (a drink known in Polish as tatanka or szarlotka; known in the UK as a Frisky Bison; and in the US as a Polish Kiss). It is sometimes served over vanilla ice cream. A Black Bison is Żubrówka mixed with black currant juice. Another common mixer is ginger ale.
