The coffee cherries must be roasted before they can become the delicious cup of coffee brewed for guests in the cafe. The coffee beans contain more than 1,000 aromatic substances as well as sugars and lipids. They undergo different chemical reactions in a heated environment, such as sugars and Menard caramelization reaction at high temperatures. With continuous heating, the fibers in the coffee beans are continuously carbonized until the coffee completely becomes charcoal.
At different temperatures and different carbonization conditions, the flavor of coffee beans will also be different. People classify the roasting of coffee beans into several roasting degrees based on the carbonization of coffee bean fibers and the color of the surface. They are light roasting, medium roasting, dark roasting, etc. Different roasting degrees have different flavors.
Generally, light-roasted coffee beans still have a high content of precursor aromatic substances, so the brewed coffee will have more acidity and less bitterness, and will have a richer regional flavor. As for medium-roasted coffee beans, because the fiber part has begun to caramelize, the flavor of baked goods such as nuts, cream, chocolate, etc. will begin to appear. Dark roasted coffee beans have a high degree of carbonization in the fiber part, low acidity, and strong bitterness, which is the mellowness that some old coffee lovers pursue, and exudes a dark chocolate, caramel-like aroma.
