​The Art of Air Roasting - Discover the Perfect Roast
​At Arise Coffee, we take pride in our unique approach to coffee roasting: the art of air roasting.
This method allows us to bring out the best in each bean, ensuring a cleaner, smoother, and more flavourful cup of coffee.
How Air Roasting Works
Air roasting uses a fluid bed of hot air to roast coffee beans, keeping them constantly suspended and moving. This method involves circulating heated air through the roasting chamber, ensuring that each bean is evenly exposed to the same consistent temperature. This precision eliminates the typical pitfalls of traditional roasting methods.
​
Key Elements of Air Roasting:
-
Fluid Bed Roasting: Unlike drum roasting, which relies on contact with heated metal, air roasting uses a fluid bed, a stream of hot air that moves the beans continuously. This allows for even heat distribution, so the beans are roasted uniformly from all sides.
-
Chaff Separation: During roasting, coffee beans shed chaff, the natural husk that surrounds the bean. In air roasting, the constant airflow removes this chaff immediately, preventing it from burning and introducing undesirable bitter or smoky flavours into the beans. The result is a cleaner tasting coffee.
-
Precision Control: The air roasting method allows for real time adjustments to temperature, airflow, and roast time. This precise control means that the roast can be customized to enhance the natural flavors of each coffee variety, bringing out fruity, nutty, chocolatey, or floral notes as intended.
Why Air Roasting is Superior
-
Consistent Heat Distribution: The air roasting technique ensures that every bean is subjected to the same heat, which reduces the chances of over roasting or under roasting. This consistency guarantees a perfect roast with every batch, free from the burnt spots or raw centers that can happen with traditional roasting.
-
No Scorching: In traditional drum roasting, beans can come into direct contact with hot metal surfaces, leading to scorching and uneven flavours. Air roasting eliminates this risk, creating a smoother and more balanced cup.
-
Better Chemical Development: Coffee roasting is all about controlling the Maillard reaction, a chemical process that develops flavour and aroma. With air roasting, the precise control over temperature and airflow allows us to optimize this reaction, highlighting the complex sugars and oils in the beans and bringing out their natural sweetness.
Understanding the Chemistry of Flavour
Coffee roasting involves complex chemical changes. During the air roasting process, the following transformations occur to create the ideal flavour profile:
-
Maillard Reaction: As the beans heat up, a reaction between amino acids and reducing sugars occurs, leading to the development of a range of flavour compounds. Air roasting optimizes this reaction, giving the beans their characteristic color and taste, whether it's chocolatey, nutty, fruity, or floral.
-
Caramelization: When sugars in the coffee beans reach higher temperatures, they begin to caramelize, creating deeper, sweeter notes like caramel, toffee, and brown sugar. Air roasting’s precise temperature control ensures that caramelization happens evenly throughout the batch, avoiding bitter, burnt flavours.
-
Dehydration and Gas Release: During roasting, the moisture inside the beans is driven out, and carbon dioxide is released. This process is carefully monitored during air roasting to preserve the beans' delicate oils, which are crucial for aroma and body. The removal of chaff via airflow also reduces the risk of bitterness.
The Benefits for Your Brew
-
Cleaner Cup: By preventing chaff from burning and avoiding direct contact with hot metal, air roasting produces a cleaner cup with a brighter flavour profile. You can expect a more transparent taste, where each bean's unique characteristics shine through.
-
Enhanced Sweetness and Acidity: Air roasting highlights the natural sweetness of the beans while balancing acidity, leading to a coffee that’s rich, complex, and full of subtle notes that reflect its origin.
-
Fresher Coffee: At Arise Coffee, we roast our beans in small batches using air roasting. This small batch approach allows us to ship coffee the same day it’s roasted, ensuring that you receive it at its peak freshness.
