@5erg I had to google kephir - it sounds absolutely disgusting!
Kefir is a fermented milk drink that originated in the Caucasus region. It is prepared by inoculating cow, goat, or sheep's milk with kefir grains. Traditional kefir was made in skin bags that were hung near a doorway; the bag would be knocked by anyone passing through the doorway to help keep the milk and kefir grains well mixed
@niftyknits interesting, it sounds so bad if you describe it hhahaha:D
but it tastes like umm......... non-flavored yoghurt. bessssssst food/drink for hangover
