Plain-language explanations appear beside the decision they support. Open the deeper lesson only when you want it.
BREW RATIOHow much water for the coffee?
A 1:16 ratio means 16 grams of water for every gram of coffee. Start with the recipe, then adjust by taste.
Learn about recipes →GRIND SIZEWhy does finer or coarser matter?
Finer coffee usually extracts faster; coarser coffee extracts slower. Change one step and keep the rest stable.
Learn about grinding →EXTRACTIONWhat do sour and bitter suggest?
Sour can indicate too little extraction; bitter can indicate too much. Baristuno treats this as a clue, not a verdict.
Learn about taste →CONTINUING YOUR COFFEE JOURNEY
Measure the grind for this cup.
COFFEE TERM · D50What does the grind number mean?
D50 is the middle particle size: half of the measured coffee is smaller and half is larger. Use it to compare your own settings—not as a universal perfect number.

02Restore a backup
Versions 1–7 are migrated to the current structure before anything is written.
03Move from another journal
Import Beanconqueror JSON/ZIP exports or a broadly compatible brew-history CSV.

Import is additive: matching backup IDs are updated, while journal imports create new records. Files are read on this device and are not uploaded as files. Account deletion still removes your stored data and sign-in permanently.

COFFEE TERM · CONFIDENCEWhy Baristuno sometimes recommends repeating
One cup can be noisy. Confidence rises when several comparable brews point in the same direction, so repeating can be a better experiment than changing immediately.
