You must start with LIVE kefir grains to make successful kefir. In this video I show a jar of already finished kefir that has fermented the day before with both milk and kefir grains.
Update: We now recommend using 2-3 cups of milk per tablespoon of kefir grains. Check out the recipe on our website:
