Extraction yield and beverage strength
How the amount of coffee extracted relates to the final beverage strength and flavor.
Consistent cup
Probes: placement, lag, calibration
Understand the critical role of temperature probes in tracking bean and environmental temperatures, ensuring accurate roast profiles and repeatable results.
Burners, airflow paths, and chimneys
Explore how burners, airflow management, and chimney design impact heat distribution, roast consistency, and smoke/degassing control in coffee roasting systems.
Development Time and DTR targets
This topic explains how to manage the development phase of roasting, including how to target the optimal Development Time Ratio (DTR) for flavor and roast consistency.
Mapping terroir to sensory outcomes
This topic explains how terroir factors such as soil, altitude, climate, and farming practices translate into sensory outcomes in the cup, and how these links are mapped and understood by producers, roasters, and consumers.
