Bean On Bar
BREWING
Start with the bean, then choose the path that matches your cup: filter brewing, espresso, Bean On Bar guidance, your own recipe, or a roaster-style recipe saved to the specific coffee.
Use origin, process, roast age, variety, and tasting notes to choose a first recipe, water temperature, grind range, pour structure, and drawdown target.
Use the same bean clues differently: dose, yield, shot style, temperature, grind-by-flow, and taste feedback guide the next adjustment.
APP FLOW
The app makes brewing useful even before a perfect bean record exists. It asks what bean context you have, then whether you want filter guidance, espresso guidance, or a saved recipe.
Use a safe baseline when you just want to brew now and adjust after tasting.
Use the current OCR/autofill fields: process, roast age, variety, origin, and tasting notes.
Pull from My Beans, keep recipe history attached, and use “Brew again” as a repeatable ritual.
Let the app choose a starting recipe and show why the brewer, ratio, temperature, grind, and timing fit.
Choose shot style, dose, yield, bean profile, and taste feedback when the same coffee is brewed under pressure.
Save a recipe locally and match it by roaster and bean name until a verified roaster recipe library exists.
Change dose, water, grind, temperature, and steps live; the app scales the structure around your input.
APP FEATURES
The website can explain the logic, while the app turns the selected recipe into an active brew session tied to the exact bean you scanned or saved.
Timer steps adapt to dose, brewer, bean signals, and the selected recipe. In the app, prompts can stay open while you brew.
Turn the recommended or custom recipe into timed step prompts, water targets, browser notifications, and vibration where supported.
Attach the exact recipe, dose, grind, temperature, and tasting result to the bean so it becomes part of your coffee memory.
Compare attempts over time: first brew, adjusted brew, roaster recipe, community recipe, and your personal best version.
Share a plain-text recipe summary, import your own roaster recipe locally, or try a recipe someone used successfully with the same bean once the community layer is live.
WHY THIS WORKS
The app gives a practical recipe quickly. This page can afford to show the recipe, the signal trail, customization, and what to change after tasting.
Washed, natural, anaerobic, roast age, roast level, variety, origin, and tasting notes change the target extraction.
V60 favors clarity, Switch can add sweetness and body, Orea is fast and repeatable, Origami can emphasize aromatics, espresso needs ratio control.
Scale water, yield, and pour structure from the chosen dose instead of forcing one fixed recipe. This mirrors the app's custom dose calculator.
Sour, bitter, thin, hollow, muted, or boozy cups get different next-step adjustments.
BREW TOOLS
The app now treats brewing as a session you can run, adjust, save, and return to—not just a static recipe card.
Show an approximate micron target by default, then translate to starter settings for supported grinders like Timemore Sculptor 064S, Varia VS6, Varia VS4, and 1Zpresso ZP6 Special.
Browser timers, notifications, and vibration are used where available, with clear limits for iOS/Safari background behavior.
Bookoo Themis Mini/Ultra Web Bluetooth support is being tested where browsers support it, with clear device limits and never a fake live reading.
Save what tasted sour, bitter, thin, hollow, muted, or boozy so the next brew starts from actual experience.
FILTER + ESPRESSO
The app now separates filter guidance from espresso dial-in, but the principle stays the same: the bean profile should shape the recipe before the brewer or machine takes over.

Future roaster submissions should override generic recommendations when verified.ESPRESSO TAB
Espresso deserves its own space because the same bean behaves differently under pressure. Bean On Bar keeps the guidance practical: choose a recipe style, set dose and yield, then adjust one variable at a time.
Modern specialty, turbo / fast light roast, classic balanced, ristretto sweetness, or long clarity shot.
Use identified or saved bean clues when available, or choose light, fruit-forward, medium, or dark as a starting profile.
Start from a realistic dose, override yield when needed, and keep ratio visible so adjustments stay understandable.
Sour, sharp, bitter, dry, hollow, fast, or slow shots each point to a different next move.
