The coffee roasting process at Blue Marlin Coffee leverages the advanced technology of air roasting, which sets their product apart in terms of quality and consistency. Using air roasters, like the fluid bed models designed by Coffee Crafters, Blue Marlin Coffee achieves a cleaner, healthier, and more precise roast compared to traditional drum roasting methods.
What Is Air Roasting?
Air roasting involves suspending coffee beans on a bed of hot, circulating air. This method allows the beans to roast evenly, as they are constantly agitated in the hot airflow. Unlike drum roasters, where beans can sit directly on hot metal surfaces and roast unevenly, air roasting ensures that each bean experiences the same temperature conditions, resulting in a uniform roast profile.
Why Air Roasting?
The decision to use air roasting stems from its numerous advantages over traditional methods:
- Cleaner Taste: The airflow eliminates the chaff (the outer skin of coffee beans) during roasting, which can burn and add a bitter or smoky flavor in drum roasting. By separating the chaff, air roasting produces a cleaner, more nuanced coffee flavor.
- Healthier Coffee: Since the process prevents burning, air roasting reduces the potential for carcinogens, making the coffee not only delicious but also heart-healthy.
- Consistent Results: The even distribution of heat ensures that every batch achieves the same quality. This consistency is critical for creating the signature blends and flavors Blue Marlin Coffee is known for.
- Efficient and Scalable: Air roasters heat quickly and can handle small to medium batches, aligning with Blue Marlin Coffee’s boutique roasting style. This allows them to respond to customer demand while maintaining freshness.
The Roasting Process
Here’s how Blue Marlin Coffee likely uses air roasters in their process:
- Selection of Beans: The process starts with high-quality green coffee beans, sourced for their unique flavors and characteristics.
- Preheating the Roaster: The air roaster is preheated to the desired temperature, usually controlled through a thermostat for precision.
- Roasting: The green coffee beans are introduced into the roasting chamber, where hot air circulates around them, gently heating them from the inside out. This process allows the beans to expand and develop their unique flavor profiles without scorching.
- First Crack and Beyond: During roasting, the beans undergo a transformation, including the “first crack,” a popping sound that signals the beans are entering the light roast stage. Depending on the desired roast level (light, medium, dark), the roaster adjusts the timing and temperature.
- Cooling and Degassing: Once roasted, the beans are quickly cooled to halt the roasting process. They are then allowed to degas for a period, releasing CO2 to ensure optimal flavor development.
- Packaging: Finally, the freshly roasted coffee is packaged to preserve its aroma and taste, ensuring it reaches the customer at peak freshness.
