Agtron

What it is and what sets it apart: Differs from commercial names (“medium”)—optical reading. Higher number = lighter. Colour, not quality alone.

How it is done: Calibrate → measure whole or ground per protocol → read → compare lots to profile goal.

Flavours and cup benefits: Aligns production and café communication. Fewer subjective colour debates.

Technical notes: Whole-bean vs ground readings differ. Same Agtron ≠ same cup if RoR changed.

Common mistakes: Do not use Agtron as sole quality proof. Do not mix meter brands uncalibrated.
