The core concept of coffee bean roasting

Coffee bean roasting is the process of subjecting raw beans to heat treatment in order to develop the flavor and aroma of the coffee. The raw beans undergo increased temperatures and chemical changes during the roasting process, resulting in the familiar coffee taste. Roasting not only changes the color of the beans, but also affects the taste and aroma of the beans, transforming them from their initial herbal flavor to a variety of complex flavor levels.

During the roasting process, coffee beans undergo a series of physical and chemical reactions. Heating causes the water inside the beans to evaporate, causing the beans to expand in volume, while Maillard reaction and caramelization occur, producing rich flavor compounds. Different roasting degrees, such as light roasting, medium roasting, and dark roasting, have different effects on the flavor characteristics of coffee, such as acidity, sweetness, and bitterness.

The purpose of roasting is not only to make the coffee beans more flavorful, but also to adapt to the taste preferences of different consumers by adjusting the degree of roasting. By fine-tuning the roasting time and temperature, baristas can develop a variety of flavor characteristics, so that each cup of coffee can show a unique flavor experience.
