Record a brew

Choose a saved recipe. Actual values below are stored as a separate snapshot; changing a recipe later will not change earlier brews.

Compare two cups

Compare a pair, then choose one change for next time. Ratings are your preference, not a professional assessment.

Keep a backup

Export downloads all bean bags, recipes and brews as a JSON file. Import adds records after validation and keeps existing work. Do not put sensitive information in notes or share a backup unintentionally.

The journal is limited to 1 MB, 200 bean bags, 500 recipes and 500 brews. Existing bag IDs keep their current local stock during import; deductions are never replayed. Deleting or undoing a brew does not restore used beans. Deleted records can be restored with Undo until another deletion or reload. Privacy details.
