OLLA BREW LAB · COFFEE COMPANION

Roast curves, brews and cuppings — one portable workbench.

SEC.02FIELD GUIDE

The Codex sits on your desk. The Field Guide walks the city.

Field Guide is built one city at a time, and four volumes are out — Tokyo 53, Osaka 38, Kyoto 36, Fukuoka 13, for 140 places in all. Every volume ships inside the app, so it reads offline, before you go looking for a signal.

  • 01Four cities, four volumes, 140 places: Tokyo 53, Osaka 38, Kyoto 36, Fukuoka 13
  • 02Fully offline — every volume downloads with the app
  • 03The list is chosen from public data by OLLA’s own algorithm, and keeps growing
  • 04Location only sorts the list on your device — never uploaded, never kept

SEC.03ROAST LAB

Put the iPad next to the roaster.

Roast Lab is a workbench for the roast floor: log events and controls as the batch runs, then replay, compare with a reference, and follow the same beans to the cup.

LIVE WORKBENCH · BATCH MEMORY

Less form-filling during the roast. More to learn afterward.

Every punch saves immediately, and timing comes from absolute timestamps — a lock screen never makes the roast clock drift.

01CHARGE → DROP

Punch events

Use large controls for charge, turning point, yellow, first crack, and drop. Each event lands on the curve.

02HEAT · AIR · DRUM · BT

Log the controls

Gas, airflow, drum speed, and bean temperature stay within reach, with large targets and haptics.

03DTR · LOSS · PHASES

Close the batch

OLLA derives total time, first crack, development ratio, and weight loss, then splits the three phases.

04GREEN → ROASTED

Track stock and output

Charging deducts green inventory, and the green record carries Green Physical, Defect Weighting, and Lot Status. Enter roasted weight and create the bean card.

IMPORT INTELLIGENCE · LOCAL PARSERS

Bring in the curves you already have.

OLLA detects the source from the file itself. Channels it cannot verify wait for you to map.

ROASTER PROFILES · VENDOR-VERIFIED

Pick your roaster. The right reader comes with it.

Thirty-five roaster models ship inside the app, every spec traced to the vendor's own documentation and left blank wherever the vendor does not state it. Choose the machine and OLLA fills in heat source, batch size and sensors, then ranks the import adapters that machine actually writes.

LOCAL-FIRST · YOUR DATA

Your files. Your data.

Files are parsed on-device, while batches and events are stored locally by default. iCloud is yours to switch on.

ON-DEVICE AI · ROAST SUMMARY

A summary drafted on your device.

On iOS 26 with Apple Intelligence, each batch gets an on-device summary draft.

CURVE MEMORY · REFERENCE

Replay the curve. Use it to guide the next batch.

Temperature and RoR share one timeline. A reference batch gives the next roast an overlay and a ghost.

  • Phase shading and event markers
  • Temperature channels and source RoR
  • Cursor readouts for BT and RoR
  • Reference curves, deviations, ghost

LAB REPORTS · A4 VECTOR

Every assessment can become a document you hand over.

Archive an assessment session and it exports as a Full Record: vector A4 in lab convention — context and extrinsic information, green physical assessment, cup descriptive and verdict, section by section — carrying your own studio name and signature. The two pages below come from one real export at full scale — not mockups.

SEC.05BEAN TO BREW

Start with the bag. Keep every brew and every cupping with the same coffee.

Photograph the bag and Apple Vision reads origin, variety, process, and roast date on your device. Confirm each field, then every brew and cupping stays with that coffee. A cupping can become a professional assessment: triggers downgrade a lot on their own, while moving up takes your confirmation — the engine drafts the hypothesis, you sign it.

01Label scan

Shoot the bag; four fields are read on device and saved to a bean card.

02Recipe timer

Pick a brewer and recipe, then follow water and pour prompts.

03Brew archive

Parameters and sensory scores in one entry; golden cups get a mark, and any record saves as a 4:5 share card.

04Professional cupping

Cup Profile 0-15, Quality Impression 1-9, and Cup Integrity across five cups; verdicts run from L5 REFERENCE to L1 REJECT.

SEC.06OLLA LAB · ASSESSMENT

Samples arrive blind. The engine drafts the hypothesis. You sign it.

Above cupping sits a professional assessment: samples are seated under blind codes, the readings feed the OLLA Lab Index, and the verdict lands on one of five OLLA Lab Classes.

OLI ENGINE · TRIGGER / OVERRIDE

Downgrades are automatic. Upgrades take a signature.

A trigger moves the class down without asking. Moving it back up takes a manual override, and the override itself stays in the record.
