Coffee Roasting Guide
The coffee is processed and dried after it is collected. The beans have a green color and a grassy flavor before the roasting is done. It is essential to note that these beans do not smell entirely like coffee. After the roasting, between 800 and 1000 aroma compound are formed. It is these compounds that make flavor in the coffee. Depending on the profile of roasting, you will have a different taste.
Roasting involves exposing the beans to a controlled high heat to trigger chemical changes. When the desired flavor is achieved; the seeds are quickly dried to stop the chemical reaction. Roasted beans smell like coffee and weighs less because the moisture has been roasted out. When the beans are roasted, they are ready to ground and brew. The beans should be used as soon as possible to prevent the aroma from fading away.

Roasting of the coffee involves three main steps. The first step involves drying of the coffee beans. The purpose of this step is to roast out the 10% moisture in the beans for about six minutes. You should ensure that you have done the process with care so that you do not burn the beans.
Browning is the next stage. The temperature in this process is over 160 degree. The precursor of the aroma compound is then converted into the aroma responsible for the flavor. In this stage, drying continue. The sugar and the amino acid in the seeds react to form color and aroma compound. The final stage is roasting. This step has to be done carefully to prevent a smoky taming and a sharp flavor. The development process takes about 20 percent time of the whole process.
Roast are of various types. Light roast is done for a short time and is suitable for the milder coffee varieties. Medium roast is medium brown and a stronger flavor. The dark roast, on the other hand, produces shiny black beans with an oily surface and a has a pronounced bitterness. The kind of roast that you choose is dependent on your preference.
