Why it matters
Without AI, inconsistent roasts, misaligned development times, off-flavor development, and delayed cupping feedback reduce origin fidelity and complicate scale-up and wholesale commitments.
From design to safety
Design
AI-guided roast profile design
The system reads target origin data, charge temperature targets, drying curve, Maillard development expectations, and cupping criteria to propose an initial roast profile and development ratio, plus a traceable baseline for repeatable results.

- Maillard development planner
- roast profile curve editor
Build
Hardware and recipe integration
Integrates calibrated thermocouples, burner controls, and roast profile software with the roastery’s PLC/SCADA to ensure traceable baseline roasts and repeatable curve generation, with documented interlock checks.

Worked example
Catching a new origin’s development window
Illustrative scenario with sample data.
A new origin with a distinct moisture profile requires a revised development ratio and Maillard window to preserve aroma notes.
Signal in
origin: X, target moisture 12.5%, development ratio 1.25, chargeTempTarget 210C, initial curve: Dry 60s, Maillard 75s, Development 28s, cuppingTarget: 83
System out
profile updated: Dry 58s, Maillard 72s, Development 30s; chargeTempTarget 212C; cuppingTarget 84; notes saved in cupping log.
Human sign-off: Head roaster reviews the updated profile and approves deployment to batch trials,QC confirms cupping scores align with origin profile.
How to roll it out
Phase 1
Weeks 1 to 2
Baseline data collection on existing origins to map current roast curves and cupping feedback loop.
Phase 2
Weeks 3 to 6
Implement AI-assisted profiles for 2 new origins with monitored outcomes and iterative refinements.
Phase 3
Weeks 7 to 8
Lock in profiles and integrate cupping feedback into supplier communications and merchandising plans.
Where people stay in charge
- Decisions about safety thresholds and alarm levels must be made by the Roastery Safety Officer or equivalent qualified person.
- Decisions about changes to critical gas valve setpoints must be signed off by the Head Roaster with QA concurrence.
- All changes to roast development curves must be signed off by the Head Roaster after cupping QA review.
Questions owners and crews ask
How does AI help with charge temperature when working with new origins?
AI analyzes origin-specific targets, compares actual charge temps, and recommends adjustments to the charger setpoint; the head roaster signs off any changes before production.
What data feeds the Maillard development decision?
The system consumes development time, development ratio, temperature progression, and cupping scores; it suggests adjustments to preserve aroma and flavor balance in the origin’s profile.
How is cupping feedback integrated into the profile?
Cupping scores, aroma notes, and body judgments feed back into the model; the software proposes refinements, and QC validates before final rollout.
What safety checks exist for changes in roast profiles?
Alarms, sensor calibrations, and interlocks verify that any changes stay within permitted thresholds; the Roastery Safety Officer approves adjustments before deployment.
