Different types of coffee have different tastes, something that can be attributed to the process used in roasting. While varieties of beans also play a key role, it does not do so as much as roasting. The beans can be roasted using an oven, gas, on a stove top, using hot air popcorn popper or using a roaster that uses hot air. During the process, approximately 10 to 20 percent of the water weight of green beans comes off. In Alaska coffee roasting can be done in various ways.
The moment they have been roasted, what follows is either drying them using air or quenching with a spray. There are packages of coffee beans that are said to be water added. This will mean that during the quenching process, approximately 12 percent and above of weight is reabsorbed into the beans. Losing of flavor in beans is mostly due to evaporation whenever flavors mixed with gases the beans.
The question of the best time to have coffee differs depending on different individuals and is dependent a great deal on personal taste. Generally, it is believed that the best time to do brewing is just after the beans have been roasted, up to after 24 hours. Grinding on the other hand is best done before the beans are roasted. There are a number of methods used to roast.
Fluid bed roasters make use of convection in cooking. Instead of direct heat, there is permeation of hot air into the interior to facilitate roasting. Heavier flavors are produced when the cooking is done for a longer time. Temperature is a very important parameter since beans are only supposed to be roasted, not burnt.
The process does not involve the use of water, as one would think because of the use of the term fluid. The term is used in reference to the movement of beans which happens fluidly. Since they are placed in a chamber used for roasting, they float on a bed of air. It is there that they are subjected simultaneously to the same temperature. The advantage of this is that it enhances consistency and rarely will there be beans in fluid bed roasters with inconsistent roasts.
The resultant flavor from drum roasted beans is very strong. On the other hand, when they are roasted for extended periods, they will develop a burnt taste. Convection is used in this technique, just like in fluid bed roasted ones. Conduction is used as well. Drum roasted beans have flavor that lingers for longer.
In contrast to fluid bed roasters, more operation training is needed for drum roasters. This explains why they are never bought for light use. One of the main reasons why they are preferred is because they are strong; they do not need high speed fans like is the case for fluid bed roasters. There is also control of air flow, with some reduction in consistency.
For the residents of Alaska coffee roasting is also able to be done from home. Pan roasting is the best method to use from home since the equipment needed is not costly and no real training is required. The majority of people do not roast coffee individually because it is time consuming and needs precision for the best results.
