Step 1

Pour water into the glass jar. Add the sugar and stir well to dissolve.

Step 2

Add the water kefir grains, the fig, and the lemon slice.

Step 3

Cover the jar with a cotton cloth and secure it with a rubber band.

Step 4

Let it ferment for 24 to 48 hours at room temperature, or until the fig has risen to the surface.

Step 5

Strain the contents of the jar. Keep the grains for your next recipe, collect the fizzy liquid (kefir) and compost the fruit.

Step 6

Add the cranberry juice to your water kefir. Mix well.

Step 7

Pour the cranberry kefir into a pressure resistant bottle.

Step 8

If desired, let the bottle ferment at room temperature for 24 to 48 hours to generate bubbles.

Step 9

After 24 hours, test the pressure in the bottles by opening the lid. If the level of fizz is satisfactory, place it in the fridge. If not, ferment a little longer.
