Frequently Asked Questions

Is home fermentation safe?: Yes! Fermented foods like kombucha have been made safely at home for thousands of years. The acidic environment naturally prevents harmful bacteria.
How long does kombucha take to make?: A typical batch takes 7–14 days for first fermentation plus 2–4 days for carbonation. Total: about 10–18 days.
Do I need a SCOBY to start brewing?: Yes — you can get one from a friend, buy online, or grow your own from raw store-bought kombucha.
Is FermentLog really free?: Yes! Track up to 2 active batches, manage your jars, and access all recipes. No credit card required.
Can I track ferments other than kombucha?: FermentLog is starting with kombucha but supports kefir, sauerkraut, kimchi, and more coming soon.
