The Brew Log is the core of the OneCup workflow: plan a recipe, brew it, save it, then change one variable next time and compare. Records stay on your device.
What you can do
- Save dose, water, ratio, temperature, time, yield, taste tags, rating, and notes.
- Duplicate your last brew and tweak a single field.
- Compare any two brews and see exactly which fields changed.
- Export to CSV or back up to JSON; restore from JSON on another device.
Your brew logs are saved in this browser only (localStorage). They are not uploaded to our servers. Use Export (CSV / JSON) to back them up before clearing your browser data or switching devices. No ads are shown in this workspace.
