Techniques Of Alaska Coffee Roasting

By Krystal Branch


There are different tastes for the different types of coffee. This difference can in a way be due to the fact that there are different roasting processes. Whereas the types of beans is also fundamental in determination of tastes, roasting is a more important factor. Beans are able to be roasted using gas, an oven, on top of a stove, using a hot air roaster or using hot air popcorn popper. In the course of the process, roughly 10 to 20 percent of water weight of green beans gets removed. In Alaska coffee roasting is done in a number of 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.

There is the use of fluid bed roasters that utilize convection to cook. Rather than the use of direct heat, hot air permeates into the interior, facilitating the process whereby beans get roasted. Cooking for a lengthy period will produce heavy flavors. Controlling the temperature is very crucial because beans are supposed to be roasted and not burnt.

The use of fluid roasters never involves the use of water as the name may imply. The term fluid is used to refer to the way in which beans moves. The beans float on a bed of air since they put in a chamber used to facilitate their getting roasted. Here, all the beans are subjected to the same temperature simultaneously. This will ensure there is consistency and it is rare to get 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.

Drum roasters require more time than fluid bed roasters. This is the reason why they are rarely purchased for light purposes. Their preference is because of the fact they are durable and will not need to use very high speed fans. Airflow is also easily controlled, albeit 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.
