Just How Does Coffee Beans Get Their Flavor For coffee beans to achieve that roasted aroma and taste, lots of things have to take place including harvesting and drying out the beans. The green coffee beans have to be heated and processed before they can even begin to take on the familiar colors, aromas and tastes of the many roasted coffee products that we are so familiar with even though the same proteins, acids and caffeine is present. While in the roasting process, the physical and chemical properties of the beans undergo a dramatic transformation, in density, taste, color and odor, depending on the length of time and intensity of the roast. During the roasting procedure, a coffee bean will go through a number of changes which dramatically alters them into a flavorful beverage. Heat causes carbohydrates (sugars) inside the beans to become caramelized, with darker roasts being characterized by greater levels of caramelized coating. As the beans are warmed to high temperatures, water is also released in the form of a vapor causing a buildup of CO2 which causes the beans to expand given them their puffed out physical appearance. Darker roasts produce bigger and lighter-weight beans. Because heat is pushing the oils out of the beans, the higher the roasting temperature, the darker the roast will likely be. These physical and chemical processes dramatically change the flavoring of the coffee bean, and controlling these processes allows modern bean roasters to produce a remarkable variety of flavor profiles. During the roasting procedure, as the coffee beans get hot the color shifts from a pale green to yellowish color and then further darken to that rich black-brown color you mostly see when choosing coffee at the stores. The beans will develop an oily outside surface and undergo cracking process apart from darkening up in color substantially. Beans will keep darkening right up until they are taken out of the roaster. Another thing that will cause the coffee beans get darkish is age, therefore color alone does not indicate the particular roasts. While in the roasting process, in order to achieve the preferred final results the roasters will monitor the beans for mass, smell, color, temperature and also sound. Sound is usually an important indication of a roasts progress; there are two temperature thresholds where coffee beans undergo cracking. Usually 401-405 Fahrenheit (205-207 Celsius) is what the temperatures must reach in the roasting process for the beans to achieve a cracking or popping sound. This threshold indicates the beginning of lighter roasts. A "second crack" is obtained when the beans hit about 435-441 degrees Fahrenheit. Due to high heat and the buildup, the pressure within the beans finally beaks down the structure of the bean and allows the discharge of gasses which will be observed with the sound it makes. Beans that have undergone a second crack are on their way to being medium or darker roasts. Expert roasters depend on sensitive equipment that is able to provide superb control over the temperature and duration of each roast, allowing them to establish a truly distinguished pot of coffee. When supplied a higher or lower intensity roast, distinctive varsities of coffee beans will taste much better than others and the roasters can establish specific roasting profiles. A roast profile is simply a ratio of the temperature of the roast to the time of the roast, and can be important for developing the best characteristic of a particular coffee bean variety. When figuring out the best profile, there are several considerations including the flavors, the aromas, the processing method, the bean variety and where and the way it was grown.
