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.
Unlike what the name implies, the use of a fluid bed roaster does not in any way involve the use of water. The name originates from the fact that beans movement occurs fluidly. Due to the fact they are placed in a roasting chamber, the beans float on a bed of air. At this chamber, they are exposed to the same temperature at the same time. This is done so that consistency is achieved when they are being roasted. There rarely are 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.
