Place Live Kefir Grains (1/2 teaspoon) into a pint-sized mason jar of Milk (1 pint).
Cover it with a plastic lid, coffee filter, or a tight (woven) cloth like a tea towel secured with a rubber band around the lip of the jar.
Set on a counter away from the light. The ideal room temperature is 75 degrees F, If it’s colder it will take longer to ferment. It will take 12-36 hours depending on the grains’ strength, temperature, and your personal taste. It is usually ready within 24 hours.
Strain the Live Kefir Grains through a fine meshed strainer into a mason jar, cover with a lid, and store in the refrigerator. It is ready to drink or use. Reserve the Kefir grains!
You can use the strained grains to start the same process over again to make the next batch of Kefir. If you need to take a break from Kefir making, place the grains in a small mason jar, fully cover grains with milk, and seal it with the mason jar lid.
For longer term storage, follow the steps through #5 but place in the freezer. It will take longer to activate them but with little effort, your grains will be as good as new. Enjoy!
