About this app

Brew mead, cider, wine (and small-batch beer) with a recipe builder + logbook that doesn’t force you into spreadsheets.
FermentaCraft is offline-first and works without an account. Use it free, upgrade once for Offline Pro, or subscribe only if you want sync + device integrations.

No account required

Start a recipe, log a batch, track fermentation—no sign-in, no ads, no “connect your email.” Your data stays yours, and you can export/import anytime.
