What each ingredient does

Mare's milk or cow's milk
Provides the base liquid and sugars that the cultures ferment into a sour, lightly effervescent drink.
Old koumiss
Supplies live cultures that start the fermentation, acting as the starter for the new batch.

The step that matters

Shaking the bottles often. Fermenting milk can separate and form firm curds that harden if left still. Regular shaking keeps the curd broken up and evenly mixed through the liquid.
