Żubrówka Bison Grass Vodka is a flavored Polish vodka, which contains a blade of bison grass in every bottle. The Żubrówka brand name is also used on bottles of conventional vodka, labeled as Żubrówka Biała. The grass is sourced from the Białowieża Forest, hand-picked and dried under natural conditions.

Vodka is a clear distilled alcoholic beverage. Different varieties originated in Poland, Russia, and Sweden. Vodka is composed mainly of water and ethanol but sometimes with traces of impurities and flavourings. Traditionally, it is made by distilling liquid from fermented cereal grains and potatoes since the latter was introduced in Europe in the 18th century. Some modern brands use corn, sugar cane, fruits, honey, and maple sap as the base.
