How Coffee Beans Are Prepared To Bring Out Flavor Freshly collected and dried coffee beans never yet have the characteristic coloring or aroma of roasted coffee. While pre-roasted beans possess many of the same components - similar proteins, acids and caffeine - the green coffee beans have to be heated before they begin to take on the recognizable colors, smells, and tastes of the many roasts and roasted coffee products that we are familiar with today. While in the roasting process, the physical and chemical properties of the beans undergo a dramatic transformation, in density, taste, color and scent, depending on the length of time and intensity of the roast. During the roasting method, a coffee bean will endure a number of transformations which dramatically alters them into a tasty beverage. The carbohydrates within the beans are caramelized when subjected to heat and the darker roasts have higher amounts of sugars. Water is also released through a vapor as the beans are warmed to high temperatures, which causes the buildup of CO2 , making the beans puff out and expand. Larger sized and lighter weight beans are produced with the darkish roasts. The higher roasting temperatures employed for dark roasts also produce beans which seem shiny, because heat has forced oils from the inside of the bean to be pushed to the surface area. These physical and chemical processes significantly change the flavor of the coffee bean, and controlling these processes allows modern bean roasters to create a remarkable variety of flavor profiles. During the roasting procedure, as the coffee beans heat the color shifts from a pale green to yellowish color and then further darken to that rich black-brown color you mostly see when selecting coffee at the stores. Along with darkening significantly, the beans will develop an oily surface, and undergo cracking. Until finally they are taken out of the roaster the beans will certainly continue to take on a darker color. Coffee beans will also get darker with age, so color alone does not necessarily indicate what roast you have. While in the roasting process, in order to achieve the preferred results the roasters will monitor the beans for mass, aroma, color, temperature and also sound. Throughout the roasting procedure, even sound is definitely an important indicator as the bean will experience cracking at two various temperatures. When roasting temperature conditions reach 401-405 degrees Fahrenheit (205-207 Celsius), the beans begin to emit popping or cracking sounds, which is recognized as "first crack." This threshold indicates the start of lighter roasts. A "second crack" is achieved when the beans hit about 435-441 degrees Fahrenheit. At this point the pressure within the beans, which has been built up as a result of high heat, finally breaks down their composition and allows the (audible) rapid release of gases. Beans that have been through a second crack are on their way to turning into medium or darker roasts. Expert roasters count on sensitive equipment that is able to provide outstanding control over the temperature and duration of each roast, allowing them to establish a truly distinguished cup of joe. When supplied a higher or lower intensity roast, different varsities of coffee beans will taste better than others and the roasters can establish specific roasting profiles. The ratio of the temperature of the roast to a specific time frame is what a roast profile consists of and is crucial when developing unique coffee flavors. When determining the best profile, there are several considerations including the flavors, the aromas, the processing strategy, the bean variety and where and the way it was grown.
