Frequently Asked Questions
Does kombucha need salt?
No. Kombucha is fermented by a SCOBY (symbiotic culture of bacteria and yeast) that feeds on sugar. Salt would inhibit the fermentation process.
Can I add salt for electrolytes?
You can add a tiny amount to finished kombucha for electrolytes, but never to the fermenting batch. Keep any additions under 0.1%.
