Fermolog started as a simple batch tracker and is now a full brewing companion. New since our first launch: Ask Fermo, an AI assistant that reads your batch details, community sharing with an Explore feed, a cellar inventory, reusable recipes, and calculators for backsweetening, carbonation and TOSNA. Now with beer, cider and kombucha support, on iOS, Android and web.

Fermolog helps you easily log, track, and visualize your home fermentation projects—whether you're crafting traditional wine, experimenting with mead, or creating fruit-based beverages.
