Water Kefir
Water kefir ferments into a bright, gently sparkling drink with clean sweetness and a soft tang from lemon and dried fruit. Tiny bubbles lift each sip while the grains quietly turn sugar into refreshing probiotic flavor.

Ingredients
- 8 cup hard water (tap water), divided
- 1/2 cup sugar
- 1/2 cup active water kefir grains, divided
- 1/2 lemon, cut into 2 wedges, divided
- 1/4 cup unsulfured dried fruit, such as dried figs, dried apricots, prunes, raisins and/or dates, cut into pieces, divided
Instructions
- Heat 1 cup water in a small saucepan until hot. Pour into a glass or plastic bowl. Add sugar and stir to dissolve.
- Divide the sugar water between 2 half-gallon jars. Add 3 1/2 cups of room-temperature tap water (65-70 degrees F) to each jar. Add 1/4 cup kefir grains to each jar and stir.
- Place 1 lemon wedge and 2 tablespoons dried fruit in each jar. Place cheesecloth over each jar and secure with a rubber band.
- Let the water rest at room temperature out of direct sunlight (65-80 degrees F) until bubbly, 48 to 72 hours. The warmer the temperature, the quicker the water will ferment.
- Using a nonmetal strainer, strain out the kefir grains and save for making another batch of kefir. Use the water kefir as is or continue onto a second fermentation to add carbonation.
- To make carbonated water: Divide the water kefir among bottles that have sealable, nonmetal lids. Leave 1 inch of air space at the top of each bottle. Seal the bottles and let rest for another 12 to 24 hours, then transfer to your refrigerator for another 2 to 3 days. You may want to "burp" the water each day to release the pressure, as sometimes the pressure gets to be too great and the water may explode.
