A simple and approachable homemade probiotic soda recipe using water kefir grains that supports gut health with a bubbly, slightly tangy, and naturally sweet flavor.

Ingredients

Scale
  • 3 tablespoons water kefir grains
  • 4 cups (1 quart) filtered water (chlorine-free)
  • 1/4 cup (50g) organic cane sugar
  • 23 slices fresh lemon or 1 tablespoon fresh lemon juice
  • 34 raisins or dried figs (optional)
  • Flavorings for second fermentation (optional): fresh ginger slices, berries, mint, basil, or fruit juice

Instructions

  1. Dissolve 1/4 cup organic cane sugar in 4 cups filtered water. Stir until fully dissolved.
  2. Add about 3 tablespoons of water kefir grains to the jar along with lemon slices and 3-4 raisins or dried figs.
  3. Cover the jar with a breathable cloth or coffee filter and secure with a rubber band. Let ferment at room temperature (68-78Β°F) away from direct sunlight for about 48 hours.
  4. After 48 hours, strain out the grains and fruit using a plastic mesh strainer. The strained liquid is your base water kefir.
  5. For second fermentation (optional), pour the strained kefir into airtight bottles, add desired flavorings, seal, and leave at room temperature for 24-48 hours to build carbonation.
  6. Refrigerate the bottles once fizzy to slow fermentation. Serve chilled.

Notes

Use chlorine-free water to keep kefir grains healthy. Avoid metal utensils as they can harm the grains. Burp bottles daily during second fermentation to prevent explosions. Keep fermentation temperature between 68-78Β°F. If kefir smells overly yeasty or pinkish, discard and start fresh. Grains multiply over time and can be shared.
