Additional Details about Milk Kefir Grains

  • Milk kefir grains are dehydrated active cultures consisting of yeast and bacteria existing in a symbiotic relationship. Milk kefir grains need to be rehydrated using pasteurized dairy milk (not raw milk) before regular use. Once milk kefir grains are rehydrated, they can be transitioned to raw milk. Milk kefir grains can be used to culture coconut, soy, or rice milk once rehydrated, but must be rehydrated in dairy milk first. Milk kefir grains require regular refreshing in fresh dairy milk (as soon as the texture changes.)

Too little of an amount

There was just too little of kefir in the bag. Maybe that’s the reason mine has finally activated after 2 weeks of trying. And i am still not sure if they’re activated. Disappointed

We're so sorry for the confusion with the Milk Kefir Grains! You only need about 1/2 to 1 tsp. of milk kefir grains to create a quart of kefir per day, and if you have more than that, it can start curdling and separating. Please feel free to contact our customer support - we can get your grains going strong!

It took much longer for the grains to reach a point where they were producing kefir then the instructions suggested (the extremely hot weather may have had something to do with that) so I turned lot of good quality milk in to curds and whey during the first two weeks and almost gave up. I'm very glad I persevered because, sometime in the third week, after cutting the quanity I was using, the milk stopped separating and began to thicken at the 12 hour point and had become a beautiful thick kefir after the full 24 hours - exactly as the instructions said it would. Overall, I am very happy with my purchase.

Kefir Grains

After a month, I have yet to see my grains multiply. The milk does thicken, but no added grains. I cannot use all of it & have dumped some. How much longer do I have to wait?

We're sorry your grains haven't grown quite yet! Check out our article on how to encourage them to grow and multiply:
very easy...still going strong.

Started about eight months ago. Grains are robust and growing over time. Almost like pets once you get used to their life style. After making too much too fast we've learned how to slow it down or speed it up by using the fridge. Too fast and you get curds, which just makes harder to screen or filter but it's still fine. If you aren't home everyday or have long days out you can simply place your milk w grains in fridge until you have time and then get it out and place at room temp for 8-12 hrs...screen and start over. We use the fridge to time and control our production. we have a quart or so of finished product in fridge for daily use. If your a milk drinker then just drink Kefir.

Easy and great

My go to for kefir Grains. I've been on kefir for over 2 years now and will never stop.
