01 -  In a clean glass jar, dissolve the cane sugar thoroughly in filtered water. Add the water kefir grains or ginger bug along with fresh lemon juice. Stir gently using a non-metallic spoon to avoid reaction. 
 02 -  Cover the jar with a breathable cloth or coffee filter and secure with a rubber band. Allow to ferment at room temperature (68–77°F) for 24 to 48 hours, or until the mixture develops a light fizziness and tangy aroma. 
 03 -  Remove the water kefir grains or ginger bug using a fine mesh strainer. Discard or save cultures for future batches. 
 04 -  Pour the fermented base into a pitcher. Add fresh orange juice, fresh lime juice, and mint leaves. Stir gently to incorporate the flavors while preserving carbonation. 
 05 -  Fill serving glasses with ice cubes. Pour the soda mocktail over the ice. Garnish with a thin slice of orange and additional mint leaves if preferred. 
 06 -  Serve immediately to enjoy optimal fizz and freshness.
