Fermolog
The brewing companion for home wine/mead makers and brewers
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.
Hey Product Hunt! 👋
I first shared Fermolog here a year ago as a simple batch tracker. Since then it has grown into a full companion for home winemakers, mead makers, brewers and cider makers, so I'm back with a fresh launch.
I started Fermolog because I wanted one clean place for everything about my batches, instead of scattered notes, spreadsheets and photos.
Here is what it does today:
🍷 Batch timeline: log notes, photos, ingredients, gravity readings and planned tasks from brew day to bottle
📈 Readings and charts: track gravity, pH and temperature, with ABV calculated automatically
📖 Recipes: turn any batch into a reusable recipe, or split a batch in two 🧮 Calculators: ABV, OG estimator, gravity/Brix, backsweetening, carbonation, TOSNA nutrient schedule and unit converters
🍾 Cellar: see how much you produced, how much is left and how old each bottle is 🌍 Community: publish batches and recipes with a share link or QR code, and explore what other brewers are making
🤖 Ask Fermo: an AI assistant that reads your batch details (ingredients, readings, notes, yeast) and answers your fermentation questions in context
It works for wine, mead, beer, cider and kombucha, and it is free on iOS, Android and web.
I'm a solo developer and I build this based on what brewers ask for, so I would love to hear from you: what is the one feature you wish your current tracking method had?
Thanks for stopping by, and cheers! 🍻
