Step 1

Puree: Remove and discard the peel from the limes. Use a handheld immersion blender or countertop blender to puree the lime flesh, mint leaves, and sugar into a smooth pulp (add a splash of kombucha if needed to get things moving). Strain mixture through a wire mesh sieve to remove fibers, collecting the minty lime juice.

Step 2

Bottle: Transfer kombucha into fermentation bottles*, leaving about 3 inches empty at the top. Equally distribute mint lime juice into bottles. Seal tightly.

Step 3

Ferment: Place in a dark, room temperature area for 3 to 10 days, until it reaches the carbonation level you like. This process will go faster in warmer climates, and slower in cooler climates.

Step 4

Enjoy: Chill in the fridge before serving. Can be stored in the fridge, tightly sealed, for several weeks.
