How To Freeze Kefir Grains For Long Term Storage

How Do You Freeze Kefir Grains?

The question of long term storage comes up quite frequently. First let me say that I do not recommend freezing water kefir grains. I find they store better dehydrated. So these instructions are for freezing milk kefir grains.

  1.  Strain the milk kefir grains from the kefir. 
  2. Gently rinse the grains with fresh clean water.
  3. Blot your milk kefir grains gently with a paper towel to soak up most of the water. 
  4. place the grains in a small mason jar or zip lock bag
  5. Add a couple of tablespoons of milk powder.
  6. Pop into the freezer.

I don't know how long the grains will stay viable like this. I have kept some in the freezer for 2 years and they worked when I took them out.

  1. I have been successful making Coconut kefir and it tastes great. The ‘Coconut Milk’ in tetrapaks if you notice are ‘Coconut Beverage’. They also are homogenized but I don’t know if that will cause bad kefir as regular milk is homogenized too. But they are loaded with additives which I didn’t like as I felt this might harm the grains. I used canned coconut milk but you should read the label to see if there are additives that might affect your grains or the kefir process. I try to find ones that have the fewest extra ingredients. They always seem to be the most expensive – of course. I like adding a banana and cocoa powder and blending. Or a banana and pineapple and blending. Almost like a pina colada. 😉

  2. Can I put Kiefer grains in milk in the fridge for a week instead of freezing? I am reducing my consumption, as I have been drinking a half cup for a wk and I am nauseated and need to make less until I build up a tolerance. How long can I freeze the kiefer milk itself?

    I heard kiefer can be made with almond milk as well, but the grain has to be transferred bk into the dairy. What is the process.

    I also read the body attacks itself if you have an auto immune condition with dairy, thryoid, and gluten proteins as they are similar and therefore dairy and wheat should be avoided by those with auto immune.

    1. Hi Vicki Thanks for your questions. You absolutely can absolutely put the kiefer grains in milk in the fridge. They will continue to ferment the milk, only much more slowly. I have not frozen fermented milk, just the grains. Freezing the milk will not hurt the bacteria, but the liquid will be much thinner and watery. Different texture. Here is an article I wrote on making kefir with non-dairy milk

      An auto-immune condition is very complicated. If dairy and wheat trigger symptoms, then definitely avoid it. Personally I eat very little wheat based products and no dairy unless it is fermented. Everybody and every body is different. Crohn’s is an auto-immune disease and some people with Crohn’s have healed their condition with kefir.

      Lots of times, it is trial and error.

    1. Hi Shantelle You can try but apparently, when frozen in liquid, the liquid expands while freezing and there is a chance for the cells to burst and become damages. In theory… you can freeze yogurt and the bacteria live even though the consistency changes so kefir might be the same. I have just never done it that way based on what I have read. If you try it, could you come back and let us know how it works? That’s how we grow our knowledge here! Thanks so much for stopping by!
