Wake up call! Here’s a pick-me-up drink with caffeine and probiotics all in one glass. This cold brew coffee water kefir soda drink is light, refreshing, low sugar and perfect served on ice.


MAKES: about 4 cups


4 cups first ferment water kefir

3 shots or 3/4 c. espresso, cooled to room temp.


  • Make the first ferment and leave the jar in a warm place for 24-48 hours.
  • Strain the grains and add the espresso to the swivel top bottle with the first ferment water kefir.
  • Seal up the swivel top bottle and leave it in a warm place for 24 hours for the second ferment.
  • Open slowly, strain and enjoy!


Increase espresso amount if you really like a stronger coffee flavour.

Add 1 tsp vanilla or a shot of coffee flavouring for a boost.

It may take a bit longer than usual for the fizz to build because there is no added sugar in the second ferment.

This coffee water kefir soda will give your body a big boost of probiotics, magnesium, B vitamins, folate, vitamin K, electrolytes and enzymes.

It contains 3 grams of sugar.
