Only in 1928, the production of Żubrówka, according to a slightly modified recipe, mainly due to the availability of bison grass, was moved to Białystok, and then in 1936 to Brześć. It was then that a blade of bison grass was put into each bottle of Żubrówka to give it a unique smell of coumarin, reminiscent of fresh hay. Throughout the period of the People’s Republic of Poland, Żubrówka was produced in Polmos in Białystok, becoming an export commodity and the pride of the Polish alcohol industry. By launching our Kniejówka, we decided to return to the roots of vodka made of bison grass, to the original recipe according to which it was produced in the interwar period in our factory, without the characteristic blade of grass in the bottle. Our Kniejówka is made of rectified rye spirit, which is mixed with a decoction of turmeric. The maceration process takes place in two stages – water and alcohol, and the resulting essence is seasoned and cleaned of sediments and possible impurities.
