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.
Various people have differing opinions on the best time to have coffee. This will mostly be dependent on personal taste. The majority of people are in agreement that the best brewing time is straight after they have been roasted, up until after 24 hours. Grinding is best done just before brewing. There are several techniques used to roast beans. During the process, the beans reach a time when they crack. Cracking can happen once or twice.
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.
Drum roasted beans have a stronger flavor. They however tend to develop burnt tastes when they are roasted for a longer time. Just like in the fluid bed technique, the beans are roasted through the process of convection, with the only difference being that conduction is also used. Drum roasted beans have their flavor lingering around for a while after the beverage is consumed. Drum roasted beans have flavor that lingers for a longer time.
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 those that live in Alaska coffee roasting can also be done from home. The best technique to use from home is pan roasting because it requires no real training or expensive equipment. Most people do not roast by themselves because it is time consuming and requires precision.
