Step-by-step instructions to ferment your own water kefir.

DAY 1

Step One: Prepare the water

Bring 4 cups of unfiltered water to a boil. Pour in your brewing jar. Add a 1/4 cup of cane sugar. Stir until dissolved, and allow to cool to room temperature.

Step Two: Add the grains (cultures)

Add a 1/4 cup of live water kefir grains to the sugar water. Close the lid but do not seal it. Leave in a consistently warm spot for 24-48 hours for the “first ferment”.

DAY 2

Step Three: Strain the water kefir

After the first ferment, strain the water kefir into a swivel top bottle using a nylon strainer and funnel. Save the grains, and return them to the brewing jar. Cover with clear water, seal and leave in the fridge until the next brew.

Step Four: Second fermentation

This is when you flavour your water kefir. We recommend adding 15 pieces of crystallized ginger and a 1/4 cup of pineapple juice into the first ferment liquid. Seal the bottle and place on the counter for 24 hours in a consistently warm spot to build fizz. “Burp” the bottle every 8 hours to avoid an overflow. Sometimes it may take more than 24 hours to build fizz, which is normal.

Step Five: Serve your water kefir

After carbonation builds in the second fermentation, put the bottle into the fridge to cool. Gently open, pour and enjoy!

Step Six: Rinse and Repeat

Sanitize your equipment, and repeat the process. It’s fun to experiment with different recipes! Click here to discover more ways to flavour your drink.
