Żubrówka is a dry, herb flavored vodka. The vodka is infused with a special grass that grows in the Białowieża forest in Poland to give it it's characteristic taste and yellowish color. The bottle also contains a blade of the grass that a bison may or may not have peed on. That doesn't bother me, it's pretty delicious.
Żubrówka has been made since the 16th century. While a form of Żubrówka can be found at select liquor stores in the US, it is not the same as the Polish version. Importing it was banned in 1978 by the Bureau of Alcohol, Tobacco, and Firearms because the grass contains a toxic compound.
Żubrówka is traditionally served chilled and mixed with apple juice, a drink known in Poland as tatanka or szarlotka. Add lime and mint for a Polish mojito.
