Inka is a Polish roasted grain beverage and brand. 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.

Inka is traditionally a mixture of roasted barley, rye, chicory and sugar beat. Cereals make up 70% of the beverage. The original Inka drink has no other ingredients and therefore has no artificial flavorings or colorings.

Inka is popular as a coffee substitute because of its more complex and sweet flavor profile, owing to the sugar beet .This is in comparison to straight roasted chicory root for example, which is another popular coffee substitute.

As an export, Inka is generally consumed in Canada and the United States.

The Inka brand also sells the Inka beverage in fortified and flavored versions. The fortified version, sometimes known as Inka Health, is fortified with Magnesium. Flavored Inka comes in caramel, chocolate or milk flavor.
