What is "podpiwek"

Podpiwek is a Polish and Lithuanian non-alcoholic beverage (even though it contains a small amount of alcohol, about 0.5%).

It is usually made from grain coffee, hops, yeast, water and sugar, which undergo fermentation.

Often created as a byproduct during beer production, it was a common drink of women and children. Its popularity diminished during the 90s, due to the availability of new Western sodas and colas, but it is regaining some of its past popularity.
