What's New in FERMNTR
2.7.0
September 14, 2026
This update brings AI to your recipes and turns your brew system into a real brewery: - Create recipes with AI: describe the beer you want and the AI recipe assistant builds a complete recipe for your brewery. It checks the numbers against the style and can use what's in your inventory. - Edit recipes with AI: ask it to swap a hop, raise the ABV or scale up the batch, and it rebalances the rest so the beer still tastes like itself. Nothing changes until you apply it. - The AI features are powered by Apple Intelligence and require iOS 27 on a supported device. FERMNTR doesn't charge for them, but Apple's own terms and usage limits apply. - Brew systems are now breweries, built from the vessels you actually own. Pick from over 130 real models like BrewZilla, Grainfather, Anvil and Spike, and FERMNTR works out the water and volume numbers for you. - Equipment checks warn you when a batch doesn't fit your brewery or the kettle is too small. - Add your own equipment steps, like whirlpool, chilling, transfer or cleaning, and they show up automatically on every brew day with that brewery. - Plus bug fixes and stability improvements for a smoother experience.
