I dried off my goats for a bit of a break from milking.
I then froze some of my milk kefir grains, I dried some of them. And I decided to experiment with some more.
I used powdered milk and fed them on this. They are producing, they are growing.
So, even powdered milk works! Good to know in a survival situation, if you can't get fresh milk, you can still keep some milk kefir grains going.
I have used one box of powdered milk, all winter, and it is a small box. My goal was just to see if they would grow and work, I didn't use my best kefir grains in this experiment. And I didn't offer them fresh made milk everyday.
