The tastes of the various types of coffee differ mainly because the processes used to roast them are different. Inasmuch as the type of beans will also contribute to the difference in taste, this is not as important a factor. Roasting of the beans can be achieved using an oven, on top of a stove, using gas, hot air popcorn popper or hot air toaster. 10 to 20 percent of water in the beans is removed during the process. In Alaska coffee roasting is done using various techniques.
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.
The technique known as fluid bed roasting uses convection to cook beans. Direct heat is not used. Instead, hot air that permeates into the interior is what makes the beans to be roasted. Lengthy cooking will produce heavier flavors. Beans should be roasted and not burnt; hence control of temperature is very important.
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 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.
