Can I generate HACCP records?

Yes. Fermento builds HACCP plans with a decision tree for hazards and critical control points, keeps monitoring and verification logs with corrective actions, and exports PDFs for audits.

Does Fermento work offline?

Yes. Everything is stored locally, and reminders fire without a network connection.

Is there Apple Watch support?

Not yet. The current version is for iPhone and iPad.

Fermento is free to download. Some features, such as HACCP plans, are part of a paid plan.

Questions

What is Fermento?

Fermento is a fermentation journal for iPhone and iPad. It keeps every batch on schedule with timelines and reminders, and logs pH, salt, weight, photos and notes in one place.

Which ferments can I track?

Sourdough feedings, kombucha brews, sauerkraut, kimchi and pickles, miso, tempeh and koji, cheese, charcuterie, mead and wine, vinegar, plus custom categories for anything else with a timer.

Does it calculate brine percentage?

Yes. Brine percent by weight, baker's percentage for dough hydration, and salt ratios for lacto ferments, in grams or ounces. A simple version of the calculator is on this site.

Can I track starters and SCOBYs?

Yes. Starters, SCOBY hotels and kefir grains have their own records with health, feeds and lineage, so you can see which batch came from which culture.
