Live Organic Certified Water Kefir Grains

Buy with confidence…

Our water kefir grains are certified by the Irish Organic Association (IOA License No: 7812). We undergo regular inspections to ensure our cultures, ingredients used and food safety management systems are up to the highest possible standard. Our water kefir grains have been cultured in a meticulously clean environment and handled with care and respect.

A large variety of bacteria have been isolated and identified in water kefir grains. Known species are among four genus groups; Lactobacillus, Leuconostoc, Acetobacter, Streptococcus and Yeasts. So far anywhere from 40+ strains of bacteria and yeasts have been identified from water kefir around the world. Our water kefir grains are known to contain over 40 strains of bacteria and yeast making it one of the best sources known worldwide.

We pride ourselves on producing only the very best water kefir grains that have been grown by professionals with all safety standards in place, using only the finest ingredients available. Authentic water kefir can only be made by using real water kefir grains and not from any kind of packet or powder!

Water Kefir vs Milk Kefir

Water kefir typically contains less bacteria than milk kefir but offers a dairy-free alternative fermented drink that can also be consumed daily. It’s easy to make, and if looked after properly, our water kefir grains will produce water kefir indefinitely so from just one purchase you can make delicious water kefir for the rest of your life!

Fermenting at home has never been easier!

  • You will receive a generous amount of water kefir grains, sent in a liquid starter solution to keep them happy and healthy on their journey to you.
  • Our grains are extremely potent and 40 grams of kefir grains will produce approx 1L of water kefir every 24-48 hours.
  • Over time, your grains will grow and multiply. This means you can either make more kefir at a time or enjoy stronger kefir in the same time.
  • Our kefir is very easy to ferment: simply place the grains in sugar water, cover loosely and leave out of direct sunlight in a warm room for 24 hours or more, depending on temperature (full instructions provided).

So we finally got around to making a how to video..

This video is not shot with a with a fancy camera or made by a professional video producer, we just wanted to show you how to get started with water kefir. Making water kefir is not difficult and in simple terms – Add sugar and filtered water to a glass jar, stir the mixture to dissolve the sugar, add the water kefir grains, let it sit, take the grains out and you are done…

Excellent grains. Very glad that we purchased. Excellent customer service too!


Our products are living cultures and for best results they should ideally be used within 48hrs of receiving them. The faster the cultures are used the higher the success rate. It is normal for cultures to take 3-5 brews to fully settle into their new environment as they are very temperature sensitive and need time to recover from the shipping process. Please see instructions for more details.
