Three Tips for Getting Your Milk Kefir Grains to Grow

march4 052

One of my favorite things about milk kefir is the continual growth of the grains. It gives you the option of making as much kefir as you could want, sharing the kefir love with friends, or using those kefir grains for something totally different, which we will be exploring later on in this series.

While the grains can be perfectly healthy without multiplying, I love the encouragement it gives me when I see them multiplying – they just seem happy.

But it’s not always as simple as keep on feeding them. Last time we explored how you need to increase the volume of milk you culture as your grains increase. This time lets explore a few other tips that I have found helpful in encouraging those grains to grow.

1. Agitate them.

Don’t annoy them, shake them. Rosalyn, a contributor here on the blog and a Customer Service Rep for CFH, gave me this little tip and it really did help. Sometimes the grains can get stagnant either at the top of the culturing jar or the bottom. Giving the jar a gentle shake every now and again through the culturing process will allow the grains access to the milk in other areas of the jar.

Fresh milk equals more food for the grains to feast on, which makes them happy and want to multiply.

2. Keep them cozy and consistent.

One of the biggest struggles I have had is keeping my milk kefir grains at a consistent temperature in the winter. If your home has cold swings, say at night or between stoking a wood stove, then you’ll want to find a place to keep them that is as insulated as possible. Wrap them in a towel or keep them near a heat source, but not too close. Temperatures over 90 degrees can also negatively effect milk kefir.

3. Keep them small.

When you first receive your milk kefir grains they are very small. As they rehydrate and gain vigor they usually grow in size and in number. If you find that your kefir grains are getting larger but are not multiplying, you could try very gently breaking them apart by rubbing them between your fingers. This increases the surface area which increases their ability to take in nourishment from the milk, which may result in grains that multiply.

So, those are my main tips.

Do you have any tips for helping milk kefir grains multiply?

    Thank you so much for these tips. I’ve never heard these before. I think I’m ready to retry milk kefir!

  2. says

    Yes, thank you! I am getting ready to start round 2 of kefir culturing at my house. My first batch never grew at all, and very so tiny after a too-long hibernation in the fridge that I gave up on them.

    i keep the grains in the fridge (covered with fresh milk) in between making batches of kefir. Should I actually be keeping them in a warm spot all the time?

      Robin – I believe you can do it either way, so long as you feed them frequently enough. The refrigerator slows down the fermentation process rapidly, so you don’t need to feed them daily in that scenario. How long do the kefir grains go in the fridge between making batches?

    What is the best way to get the grains out of the kefir? I have the white plastic strainer from Cultures for Health and it does not work to pour it thru….thanks

    I am still in the rehydrating phase I think. It’s day 4 and today I got my first batch with the slight sourness to it. Yesterday it was too warm and I made curds and whey…should have stuck to the12 hour vs the 24 hr marker. But my grains are SO small I can’t hardly even tell where they are. I mean I think they are about the size of a grain of sand. I feel like I am trying to distinguish them from the curds. Is this normal and when will they become large enough to really identify? Thanks.

    I have learned over the past year that fresh raw milk will make them grow beautifully. I have used store bought organic milk for the past year while making my kefir milk and they never grew. I recently found raw milk close by and they absolutely love the raw milk. After the first fermentation I noticed my grains plump up.

      Thank you Michelle.
      I will go with the shaking and raw milk.
      I came here looking for answers and I do believe I have found them.
