01 - In a sanitized glass jar, dissolve cane sugar in filtered water. Incorporate water kefir grains or ginger bug, along with fresh lemon juice. Use a non-metallic spoon to mix gently.
02 - Cover the jar with a breathable cloth or coffee filter, securing with a rubber band. Leave to ferment at room temperature (68–77°F) for 24 to 48 hours, until the mixture becomes lightly carbonated and tangy.
03 - Remove kefir grains or ginger bug using a fine mesh strainer. Discard, or reserve cultures for future use.
04 - In a pitcher, blend the fermented soda base with orange juice, lime juice, and mint leaves. Stir gently to combine.
05 - Fill serving glasses with ice cubes. Pour soda mocktail over ice, garnishing each glass with an orange slice and additional mint as desired.
06 - Serve immediately to retain optimal effervescence and freshness.
