Coffee bean roasting: incorporating multiple flavors

The multiple flavors of roasted coffee beans

Coffee bean roasting is the process of heating raw beans to produce a specific flavor and aroma. Through different roasting degrees and methods, you can get coffee with different tastes and flavors. The following will introduce several common coffee bean roasting methods and the multiple flavors they bring.

Light roast

Light roasting means heating the coffee beans to an internal temperature of 180-205°C, a process that usually lasts 10-12 minutes. Light roasting retains a higher moisture content and acidic substances, so it has bright, refreshing, and fruity characteristics. This type of coffee usually has citrus, floral or herbal aromas, and tastes spicy and fresh.

Medium (American) preparation

Medium (American) roasting means that the coffee beans are processed until the internal temperature reaches between 210-220°C, which takes about 12-14 minutes. This degree of roasting reduces the acidity inside the coffee beans, producing more sweetness and bitterness. This type of coffee usually has a nutty, chocolate or caramel aroma, and a round and balanced taste.

Deep (French) preparation

Deep (French) roasting means processing the coffee beans until the internal temperature reaches between 225-230°C, which takes about 14-16 minutes. This degree of roasting further reduces the acidity inside the coffee beans, producing more bitterness and caramel. This type of coffee usually has a cocoa, wood or tobacco aroma, and a rich and full taste.

Special treatment

In addition to different degrees of roasting, there are some special processing methods that can bring additional flavors to coffee beans. For example, adding fruit juice or other natural seasonings during the fermentation process can give coffee a strong fruity aroma; freezing treatment can retain more of the original flavor; and pre-treatment before roasting, such as washing or honey treatment, can change the flavor characteristics of coffee beans.

Conclusion

Coffee bean roasting is a delicate and complex process. Different roasting methods and processing methods will bring rich and diverse flavors to coffee. Whether you like a fresh and bright taste or a rich and full taste, you can choose the coffee bean roasting method that suits you according to your taste preferences.
