diverse levels of roasting provide diverse flavor profiles in coffee beans. Light, medium, and dark are the typical categories for the roasting stages. Dark roasts are more bitter and have a smokey flavor, whereas light roasts are often more acidic and have a fruity taste. Medium roasts fall in the middle and have a harmonious flavor profile. Temperature of a full city roast
Coffee enthusiasts favor the medium-dark roast known as Full City Roast. A temperature of roughly 225-230°C (437-446°F) is reached during roasting. The beans begin to produce a sheen of oil on their surface at this temperature, signifying that they have been sufficiently roasted to release all of their flavor. With hints of chocolate and caramel, the flavor profile of Full City Roast is well-balanced. Coffee Processing Techniques
Coffee beans are treated using a variety of techniques in addition to different roasting degrees. There are three major ways to process coffee: washed, natural, and honey. The outer covering of the fruit is removed before drying to process washed coffee beans. As a result, the flavor profile is clear and vibrant. Natural coffee beans have a fruitier and sweeter flavor profile since they are dried with the fruit still on them. Honey coffee beans have a sweet and syrupy flavor characteristic because some of the fruit is still there when they are dried. Moisture Content
The roasting process depends on the amount of moisture in the coffee beans. Before roasting, beans should be dried to a moisture content of between 10 and 12 percent. A bitter flavor might emerge from the beans burning during roasting if they are excessively dry. If they are excessively wet, mold or bacteria may grow on them and alter the flavor of the coffee. Temperature for Roasting
Depending on the desired flavor profile and roast level, several temperatures can be used to roast coffee beans. The normal roasting temperature for light roasts is 180–205°C (356–401°F). Roasting temperatures for medium roasts are higher, averaging 210–220°C (410–428°F). The highest roasting temperature for dark roasts is 225–230°C (437–446°F).
In conclusion, experimentation is the key to finding your favorite coffee roast. To determine which roasts and processing techniques best suit your palate, experiment with several roasts. Try something new and don’t be afraid to leave your comfort zone. Who knows, you might find a new favorite roast of coffee!
