We are currently proudly supporting the Citizen Science project:

“The Citizen Science project is part of the EU funded MASTER project and is happening in collaboration with Teagasc, APC Microbiome Ireland, and VistaMilk. The aim of the project is to look at the microbial diversity of water kefir throughout an extended period of fermentations. The citizen scientists were given our water kefir grains and equipment to ferment water kefir at home for ~5 months. During this time, water kefir samples will be collected by the researchers and analysed for their microbial composition to investigate how water kefir grains are adapting to different fermentation settings and practices.”

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…
