Benefits of Air Roasting Coffee Instead of Drum Roasting
Coffee roasting is the process of heating green coffee beans to a high temperature until they reach the desired color and flavor profile. There are two main methods of coffee roasting: drum roasting and air roasting. You ask why do I care ?
Drum roasting is the more traditional method, and it involves tumbling the green coffee beans in a large, heated drum. Air roasting is a newer method that involves suspending the green coffee beans in a stream of hot air.
Both methods of coffee roasting have their own advantages and disadvantages. However, air roasting is often seen as the superior method due to its many benefits.
Here are some of the benefits of air roasting coffee instead of drum roasting:
- More consistent roasts: Air roasters use digital temperature sensors to monitor the temperature of the coffee beans throughout the roasting process. This allows the roaster to have greater control over the roast and produce more consistent results.
- Cleaner flavor: Air roasters remove the chaff from the coffee beans during the roasting process. Chaff is a thin layer of skin that covers green coffee beans, and it can impart a bitter flavor to the coffee if it is not removed. Air roasting produces coffee with a cleaner, more nuanced flavor.
- Less acidity: Air roasting takes less time than drum roasting, which results in coffee with less acidity. This is because the coffee beans have less time to develop the compounds that contribute to acidity.
- Healthier coffee: Air roasting produces coffee that is higher in antioxidants and lower in acrylamide, a potential carcinogen. Acrylamide is produced when coffee beans are roasted at high temperatures for a long period of time.
Overall, air roasting is a superior method of coffee roasting because it produces coffee that is more consistent, has a cleaner flavor, is less acidic, and is healthier.
If you are looking for the best possible cup of coffee, be sure to choose coffee that has been air roasted.
