I love kefer, fermented foods of all kinds are great for our digestive system and mental health. My Korean Buddhist teacher used to feed me pressed pine pollen cookies that looked flowers and green tea.
I've made kefer and yogurt from raw cows milk. I don 't drink milk products sold in our store because they are cooked at a high pressure heat which deforms the protiens and makes my tummy hurt.
Excellent information @turkishcrew <3
