Kaffeeröstung

Kaffeeröstung, also known as coffee roasting, is the process of heating coffee beans to transform their chemical and physical properties. This process enhances the flavor, aroma, and color of the coffee. There are various methods of coffee roasting, but most involve heating the beans to a specific temperature, usually between 400°F and 435°F (204°C to 224°C).

The roasting process can be divided into several stages: drying, light roasting, medium roasting, and dark roasting. During the drying stage, the beans lose their residual moisture. Light roasting results in a mild flavor, while medium roasting produces a balanced taste. Dark roasting, the final stage, imparts a rich, caramel-like flavor.

Roasting coffee beans brings out the desirable flavors and aromas that are hidden within the unroasted beans. The heat from the roasting process breaks down the enzymes, allowing the coffee's natural oils to be released. The beans' chemical composition changes, resulting in the characteristic flavors of roasted coffee.

The time and temperature of the roasting process significantly affect the quality and taste of the final product. Some coffee roasting methods include drum roasting and continuous roasting. Drum roasting involves heating the beans in a rotating drum, while continuous roasting involves a conveyor belt-style system.

The roasting process also impacts the coffee's color, which can range from light beige to dark brown. The peak of the roasting process is referred to as "first crack," when the beans expand and release their moisture. A second crack occurs around 440°F (227°C), resulting in an extremely dark roast. Each roasting method and time produce distinct flavors and aromas, which can vary depending on the bean origin and roasting technique.
