Roasting
Profile Roasting
The practice of designing and replicating specific time-temperature curves to achieve target flavor outcomes, using data logging software and precise burner, airflow, and drum speed controls.

Profile roasting treats each coffee as unique, with variables like density, moisture, screen size, and processing method informing a custom roast plan. Roasters develop profiles through systematic cupping of sample roasts, adjusting charge temperature, gas ramps, airflow adjustments, and development time. Software platforms like Cropster, Artisan, and RoastPath store profiles for batch-to-batch replication and allow overlay comparison between roasts. This data-driven approach has replaced intuitive 'roast by sight and smell' methods in most specialty operations.
