Kvass starter? I typically just use yeast, old rye bread, raisins, and sugar. Maybe added lemon for taste at the end.

This recipe is similar to how I make mine (in Russian): https://www.gastronom.ru/recipe/55100/domashnij-kvas-iz-hleb...

TIL.. When I saw kvass being made I was too young to know how it works.
