01 - In a sanitized glass jar, dissolve the cane sugar fully in filtered water. Incorporate either water kefir grains or ginger bug and add fresh lemon juice. Stir gently using a non-metallic spoon.
02 - Cover the jar with a breathable cloth or coffee filter and secure with a rubber band. Ferment at room temperature (68–77°F) for 24 to 48 hours, until the mixture becomes lightly carbonated and tangy.
03 - Carefully strain out the kefir grains or ginger bug using a fine mesh strainer. Discard or reserve cultures for future use.
04 - Transfer the fermented soda base into a pitcher. Add fresh orange juice, lime juice, and mint leaves. Stir gently to combine without deflating the fizz.
05 - Fill glasses with ice cubes. Pour the mocktail over ice and garnish each serving with a thin slice of orange and additional fresh mint leaves if desired.
06 - Serve promptly to preserve freshness and carbonation.
