Not growing

I did exactly what they told me to do for the second batch and the kefir has not done anything. There's no lovely yeast smell to it that should be there. I am disappointed that we ran into this again. I wanted to support an independent business, but I think I'll go back to Amazon to get the ones that worked for me the last time.

Water kefir grains are known to multiply, but at times they are reluctant to do so. Even if they do not multiply, with proper care, kefir grains can be used indefinitely to brew milk kefir. Generally kefir grains take 6 to 8 weeks following rehydration to begin multiplying.

Great Grains!

I have purchased grains from other sources in the past. These are the best!


I love water kefir and this culture works perfectly.

Great product, easy to use

So far I ordered tempeh starter and water kefir grains. The tempeh turned out great. I’m still experimenting with the water kefir. I live in the tropics and I had trouble with tiny ants getting into the sugar water. I ended up submerging the jar into a water as a barrier for the ants. After the 1st fermentation it tastes too sweet and flat for my taste so I moved straight to 2nd fermentation. It’s fun to experiment with these products. I really enjoy watching the „How to“ videos and the explanation included in the packages is great and easy to follow. An awesome company making healthy probiotics more accessible and easy to prepare.

Didn’t work at all

I rehydrated the kefir grains exactly according to the directions. Then I put the kefir grains in coconut water. They never made kefir coconut water. They just sat in the coconut water taking up space. I had to throw the whole batch out. What a waste!

We're so sorry your water kefir grains don't appear to be working! First, make sure to give them enough time to 'wake up' in sugar water before switching to coconut water. Please feel free to contact our customer support team so we can get them turned around!
