Homemade Kefir Soda: Healthy Fizz!
A naturally fizzy, probiotic-rich fermented drink made from water kefir grains, offering a delicious and gut-healthy alternative to sugary soft drinks.
Ingredients
- 1/4 cup active water kefir grains
- 1/4 cup cane sugar
- 4 cups filtered water room temperature
- Optional - fruit juice or fruit slices for second fermentation
Instructions
- 1. Dissolve the cane sugar in a small amount of warm filtered water in a clean glass jar. Once dissolved, add the remaining room temperature filtered water to cool the mixture. 2. Add the active water kefir grains to the sugar water in the jar. 3. Cover the jar with a breathable cloth (like a coffee filter or cheesecloth) and secure it with a rubber band. This allows air exchange while keeping contaminants out. 4. Place the jar in a warm spot (ideally 68-75°F or 20-24°C) away from direct sunlight for 24-48 hours. The fermentation time will vary based on temperature and desired tartness. Taste periodically until it reaches your preference. 5. Once fermented, strain the kefir liquid into a clean bottle, separating the water kefir grains. You can store the grains in fresh sugar water in the refrigerator for future use. 6. (Optional Second Fermentation for Fizz & Flavor): For extra carbonation and flavor, pour the strained kefir liquid into flip-top bottles. Add your desired fruit juice, fruit slices, or other flavorings. 7. Seal the bottles tightly and let them sit at room temperature for another 12-24 hours. This creates the natural fizz. Periodically 'burp' the bottles (open and close quickly) to release excess pressure and prevent explosions. 8. Once desired carbonation is achieved, refrigerate the finished kefir soda to slow down further fermentation and enjoy chilled.
Notes
Experiment with different fruits (berries, citrus, tropical fruits) or flavorings like ginger, mint, or vanilla extract during the second fermentation. For a stronger fizz, allow more time in sealed bottles, but 'burp' them daily to prevent excessive pressure buildup. If your grains aren't fermenting, try adjusting the sugar-to-water ratio or ensuring optimal room temperature.
