Roasting Intermediate/Professional

Roasting Intermediate/Professional

The structure and focus of the SCA Roasting Intermediate and Professional modules, which train roasters to move from operational competence to mastery of profiling and production systems.

Temperature profiling and surfing

Temperature profiling and surfing

How temperature profiling and temperature surfing influence espresso extraction, especially across roast levels and machine types.

Flow-regulated extractions

Flow-regulated extractions

How flow-regulated espresso extractions differ from pressure-based methods, and how they influence consistency, puck integrity, and flavor.

Triangle testing and statistics

Triangle testing and statistics

How triangle testing is used in coffee sensory science to determine whether detectable differences exist between samples, and how statistics validate the results.

PID control and temperature stability

PID control and temperature stability

How PID (Proportional-Integral-Derivative) controllers improve espresso machine temperature stability and extraction consistency.
