Basic concepts and common methods of coffee bean roasting

The roasting process of coffee beans is a key step in heating the raw coffee beans to cause chemical changes inside them to release their flavor and aroma. During the roasting process, the coffee beans will go through different stages from light to deep, and each stage will affect the flavor characteristics of the final coffee. Generally, the roasting process includes preheating, drying, roasting and cooling stages.

Medium roast refers to the degree of roasting before the coffee beans reach the second crack. This roasting method retains more of the original flavor and acidity of the coffee beans. Medium roasted coffee usually has a balanced flavor, moderate acidity and moderate bitterness, and is the first choice of many coffee lovers.

Dark roasted coffee beans are roasted after the second crack. At this stage, the coffee beans have a darker color, rich caramel flavor and obvious bitterness. Dark roasted coffee beans often have a smoky or chocolate flavor, which is more suitable for people who like strong-flavored coffee.

Common roasting methods include airflow roasting and drum roasting. Airflow roasting uses strong airflow to suspend the coffee beans in the roasting chamber, which is suitable for medium roasting; drum roasting uses a rotating drum to evenly heat the coffee beans at high temperature, which is more suitable for deep roasting. Understanding these basics can help you better choose and enjoy coffee of various flavors.
