02 · Precision, revealed
Human judgment · Instrument memory
Every degree leaves a signature.
Traditional sensory craft stays at the center. Data gives it a memory—so one remarkable roast can become a reliably remarkable cup.

01 · The transformation
One seed. Four decisions.
Select a stage or play the sequence. Each moment changes the material, but no single instrument gets the final word.
02 · The roast ledger
Taste, translated into numbers.
These are design-draft values, showing how production data can remain legible and beautiful without becoming clinical.
- Development ratio
- 18.4%
- Green moisture
- 10.7%
- Total roast time
- 10:12min
Calibration plate · RR-P13 · Providence production roast
03 · Human + instrument
Measure what helps. Taste what matters.
- 01
Read the green
Moisture, density, processing method and screen size tell us how the coffee is likely to accept heat.
- 02
Design the curve
The target cup becomes a starting profile: charge temperature, turning point, rate of rise and planned development.
- 03
Roast with attention
Sound, smell and color remain active signals. Sensors sharpen the picture without taking the roaster out of it.
- 04
Cup, record, repeat
Agtron, mass loss and sensory notes close the loop. Drift becomes visible and good decisions become repeatable.
Precision is not the removal of instinct. It is how instinct learns to remember.

The method explains how we work. The emblem explains why the work exists at all.
