Inka is a Polish roasted grain beverage. Developed in the late 1960s during communist rule, Inka has been produced in Skawina since 1971, a centre of coffee production since the early 20th century. Presently it is manufactured by GRANA Sp. Z O.O. While it was used in part as a coffee substitute to alleviate coffee shortages in the 1970s, Inka remains popular, in part to the fact that it is caffeine-free.
