Milk Kefir Grains
Product Review (submitted on August 30, 2013):
The shipped grains re-hydrated quickly and easily.
The Cultures for Health grains are very active. 1/2 tsp of my grains cultures a cup of milk in less than 24 hours. I keep discarding grains, but it doesn't slow it down! It's like a hungry pet that wants to eat all the milk in the house!
The grains make more kefir than I can drink so 3 months ago, I put the grains (in kefir, so not a lot of food for them) into the fridge and left it there. I assumed they were dead, but I started to feel bad and decided to revive them. They're alive! After a few not-quite-right batches, they're just as active and tasty as they were before the neglect.
Kefir is amazing stuff!
