Kombucha fermentation creates real pressure. This calculator provides estimates for carbonation levels based on general formulas.
Always use pressure-rated, flip-top bottles designed for carbonation. Never reuse standard thin-glass kombucha bottles or sauce jars, as they may explode.
Always store fermenting bottles in a container (like a plastic bin) to contain any accidental breakage.
