Built for Real Makers
Everything a cider maker or winemaker needs to log, measure, and manage — all in one app.
Log specific gravity (SG and Brix), pH, titratable acidity (TA), free and total SO2, YAN (yeast assimilable nitrogen), temperature, and volume at every stage. ABV is calculated automatically from your gravity readings. Track trends over time with built-in charts.
Record apple or grape weight, juice yield, and extraction efficiency for every pressing session. Track fruit costs per kilogram, link pressings directly to batches, and compare yields across seasons and varieties.
Every ingredient you add to a batch is costed automatically. The app calculates cost per litre and cost per bottle across your entire production. Inventory stock is deducted as you use items in batches and bottling runs.
Browse in-app guides covering apple varieties for cider, grape varieties for wine, yeast strains with grape pairings, tannin management, fermentation faults, blending formulas, SO2 management, and more. Learn while you make.
What Makers Say
"Finally an app that understands the full process from pressing to bottling. Everything is tracked in one place — gravity, SO2, additions, costs."
Home Orchard, UK
"The team feature is brilliant. My whole crew logs readings and additions from their phones, and I can see everything from my desk."
Small Cidery, USA
"I switched from spreadsheets and haven't looked back. The calculators alone save me time every brew day."

FAQ
Yes. You get up to 10 batches and 10 pressings, all calculators, analytics, exports, inventory, tank management, and guides completely free forever. Your data is stored locally on your device. Pro unlocks unlimited batches, cloud sync, team sharing, and access on all your devices.
Absolutely. Fermentation Buddy is built for both cider and wine makers. It includes grape variety guides, wine yeast pairings, SO2 and chaptalization calculators, and tracks all the measurements wine makers need — specific gravity, pH, titratable acidity, free SO2, and more. It works equally well for mead and other fermented beverages.
You can log specific gravity (SG and Brix), pH, titratable acidity (TA), free and total SO2, YAN (yeast assimilable nitrogen), temperature, and volume at every stage of fermentation. The app calculates ABV automatically from your gravity readings.
Fermentation Buddy is available on Android (Google Play), Web (any browser at app.fermentationbuddy.com), Windows, macOS, and Linux. With a Pro subscription, your data syncs across all platforms automatically.
You keep access until the end of your billing period. After that, your data stays safe in the cloud but you'll switch to local-only mode with up to 10 batches. You can re-subscribe anytime to restore full cloud access.
Pro Team and Business plans let you create a group and invite members. Everyone gets both a personal workspace and a shared team workspace. The group owner controls membership and can include non-Pro users who get Pro access through the team plan. Great for cideries, wineries, and homebrew clubs.
Yes. On Android, Fermentation Buddy connects to RAPT Pill and Tilt digital hydrometers via Bluetooth for automatic gravity and temperature readings directly into your batch log.
Web subscriptions are handled through Stripe, a secure payment processor. On Android, payments go through Google Play. Both options offer the same Pro features and you can cancel anytime.
Free on Android and Web. No account needed — start logging batches in minutes.
