About this app

Brew better kombucha, batch after batch. Fermenta keeps every stage clear, from first fermentation (F1) through bottling, second fermentation (F2), chilling, and the first sip. TRACK EACH BATCH • See day-by-day progress, target dates, and the next step. • Get local reminders when it is time to taste, bottle, check carbonation, chill, or finish. • View active brews in Home Screen widgets and plan bottling, chilling, and ready dates in a calendar. KEEP A USEFUL BREW LOG • Record tea, volume, sugar, starter liquid, start dates, and notes. • Log flavor, pH, temperature, carbonation, and pressure releases at the relevant stage. • Split one batch into bottle groups and choose from 40 built-in flavors or add your own. • Rate finished batches, add tasting notes, brew a favorite again, and share a clean summary card. LEARN AS YOU BREW • Follow a practical guide to first and second fermentation. • Find quick answers in troubleshooting, FAQs, and the glossary. • Scale tea, sugar, and starter liquid for any volume with the ratio calculator. • Answer a few questions and compare real reference photos in the guided mold check. PRIVATE BY DESIGN Your brewing data is stored on your iPhone. When iCloud is available, batches, custom flavors, and SCOBY hotels sync through your private iCloud database. Fermenta works offline, with no account, no ads, and no cross-app tracking. Brew as many batches as you like, one at a time. Fermenta Pro is an optional one-time purchase that unlocks unlimited active batches and the SCOBY hotel. No subscription. Fermenta offers brewing guidance, but it cannot determine whether a batch is safe to drink. If a batch has an unusual odor, shows mold, or seems unsafe, do not drink it.
