Servings: 3 portions


  • 750 ml water
  • 40 g light brown sugar
  • 25-30 g organic water kefir grains


1st Ferment

  • Combine the water and sugar and stir until the sugars are completely dissolved.
  • Pour the sugared water into a Mason jar. Carefully place the grains into the sugar solution. Cover with a muslin or tea-towel and add a rubber band or string to keep it in place. Allow to brew at room temperature for 24-48 hours, no longer. Store away from direct sunlight.
  • When the water kefir is done brewing, simply strain the grains out and keep approximately 25ml for the next brew. You can now either start the next batch right away with the kefir grains, or make a SCOBY hotel (symbiotic culture of bacteria and yeast) in the fridge to store the grains until next time. (To do this add a teaspoon of light brown sugar to 20ml water and stir, add the grain and cover with a lid).

2nd Ferment

  • To get your water kefir carbonated, Return the kefir water to the jar and add fruit and herbs of your choice. Close the tight fitting lid and leave to ferment for another 24-36 hours. When fermentation has finished, transfer to lidded bottles and store in the fridge. Enjoy over ice.
