Dried Milk Kefir Grains
Milk kefir grains are live active cultures consisting of yeast and bacteria existing in a symbiotic relationship. Once reactivated (instructions included) you just put them in fresh milk and they turn it into a tasty probiotic yogurt-like drink every day. With proper care, this little packet of grains will reculture indefinitely and will even reproduce, giving you a lifetime of kefir. Wow!
Contains the dried equivalent of 1 Tbsp fresh grains (enough to ferment 1 liter milk at a time to start, but they grow). Takes a few days to a couple weeks to reactivate by placing in 1 cup fresh milk each day.
