At Camel Step, we believe that coffee is not just a beverage; it is an experience. Every cup tells a story of the beans’ origin, the careful roasting process, and the expertise behind it. Coffee roasting transforms green beans into aromatic, flavorful coffee through precise control of temperature, time, and airflow. While often described as an art, roasting is primarily a science- and technology-based process, built on years of collective knowledge and experimentation. The skill lies in identifying the optimal roasting conditions for each coffee lot to bring out its unique characteristics and achieve a perfectly balanced flavor.
Key Phases of Coffee Roasting
The roasting process involves a series of physico-chemical transformations. Although continuous, it can be divided into several main phases for clarity and understanding.
1. Drying Phase
Roasting begins with the drying phase, during which free water is removed from the beans. The temperature gradually rises according to the roast profile, preparing the beans for the chemical transformations in the subsequent stages.
2.Transformation Phase
As the beans heat up, they begin to turn light yellow. This phase involves:
Additional removal of bound water
Minor molecular restructuring
Initial breakdown of cell structures in preparation for main roasting reactions
This stage lays the foundation for flavor development in the next phases.
3. Browning Phase (Maillard Reaction)
This is the core flavor and aroma development phase:
Maillard reaction between sugars and amino acids produces melanoidins, responsible for the brown color and complex flavors
Internal pressure rises due to water vapor release and molecular reorganization
First Crack occurs, signaling the transition to the development phase
4. Development Phase
Following the first crack, the development phase fine-tunes the coffee’s final flavor. Precise control of time and temperature is critical, as even small differences of 5–10 seconds can significantly affect the balance of acidity, sweetness, and bitterness.
The duration of this phase depends on the intended brew method: filter, espresso, or traditional Saudi coffee
5. Cooling Phase
Once the desired roast is reached, beans are dropped from the roaster and cooled rapidly for 5–10 minutes. Cooling halts chemical reactions and stabilizes the final flavor.
Specialty vs. Commercial Roasting
Specialty Coffee: Roasting typically ends shortly after the development phase to preserve delicate aromas and flavors.
Commercial Coffee: Beans are roasted darker, often reaching or surpassing the second crack, which mutes off-notes but reduces subtle, desirable flavors.
Saudi Coffee Roasting: Traditional Saudi coffee stops near the end of the transformation phase and is cooled immediately. This preserves lighter, delicate flavors and maintains the signature profile of Saudi coffee.
At Camel Step, we apply this scientific understanding to every batch to ensure coffee that is consistent in quality and rich in flavor, whether brewed as filter, espresso, or traditional Saudi coffee. Mastery in roasting is what makes every cup exceptional.
