Roast levels: light to dark
This topic examines the spectrum of roast levels, from light to dark, and how each affects coffee flavor, aroma, and body.
Tips roasters
Color changes and caramelization
This topic explores how coffee beans change color during roasting and the role of caramelization in flavor development.
Charge temp and turning point
This topic explains the significance of charge temperature and the turning point in coffee roasting, and how they affect bean development and final flavor.
Gas, airflow, drum speed controls
This topic covers how key roaster controls—gas (heat), airflow, and drum speed—affect roast development, bean temperature, and flavor outcomes.
Endothermic vs exothermic transitions
This topic explains the thermal events during coffee roasting, highlighting the difference between endothermic and exothermic reactions, and how these affect roast control and flavor development.
Rate of Rise (RoR) interpretation
This topic covers how to interpret the Rate of Rise (RoR) during coffee roasting, why it’s crucial for controlling roast development, and how to make real-time adjustments based on RoR trends.
