OLLA Brew Lab

OLLA ROAST LAB · ROAST WORKFLOW

A roast log that stays useful after drop.

Import an existing profile or record a batch beside the roaster. OLLA keeps the curve, events, controls, inventory, cupping, and brew results connected—so the next decision starts with evidence instead of memory.

FROM PROFILE TO CUP

One batch. Four useful stages.

Roast Lab is designed as a field notebook and analysis companion for serious home roasters, sample roasting, and working roast teams.

01

Import

Bring in a curve from supported roasting software or a mapped text file.

02

Record

Punch events and log gas, airflow, drum speed, BT, and notes while the batch runs.

03

Review

Replay temperature and RoR, compare profiles, and choose a reference for the next roast.

04

Connect

Carry the batch into inventory, bean cards, cupping, brewing, and lab-style reports.

IMPORT · LOCAL PARSERS

Use the curves you already own.

Parsing runs on the device. OLLA detects common delimiters, time axes, temperature units, events, and available channels, then leaves uncertain mappings for you to confirm instead of silently guessing.

LIVE BATCH · IPHONE + IPAD

Built for the moments when timing matters.

Large targets keep essential actions close. Every event is saved immediately, and the roast clock is derived from absolute timestamps so a lock screen or interrupted session does not introduce drift.

  • Charge, turning point, yellow, first crack, and drop markers
  • Gas, airflow, drum speed, bean temperature, and batch notes
  • Drying, Maillard, development, DTR, total time, and weight loss
  • Green-coffee deduction, roasted output, and bean-card creation

CURVE MEMORY · COMPARISON

Replay the curve. Make the next batch more deliberate.

Temperature and RoR share one timeline. Scrub to any point, compare event timing, set a reference curve, or follow a live ghost during the next roast.

  • Playback, speed control, and cursor BT / RoR readouts
  • Phase shading, event markers, and multiple temperature channels
  • Reference overlays, event deviations, and live ghost
  • Three-batch comparison with PDF and PNG outputs

ROAST TO CUP · RTC

The record continues after the roaster stops.

A roast becomes more useful when it can be read beside the coffee it produced. Link the batch to a bean card, resting window, cupping sheet, brew logs, and a report you can archive or discuss with a team.
