Origin, variety, altitude, soil type processing, and brewing all affect how your coffee tastes when it ends up in your cup. If we had to choose one thing that can be a major influence on the taste of your coffee that would be roasting.
The process of roasting @!%G2A is in use since the dawn of civilization realized that they could produce an exquisite, powerful drink from the coffee cherries plant. Roasting coffee beans began in the beginning of roasting coffee beans in open flames. In the past, many improvements have been implemented to the roasting process.
Roasting coffee beans is considered to be both an art AND a science. Unskilled roasters could easily destroy beautiful coffee beans. To discover the true nature of any green coffee requires the right amount of experience, knowledge, and the "sixth sense" of the roaster.
Now let's take a deeper review of the coffee roasting process and how it affects the brews that you enjoy every day.
Coffee bean roasting can be described as cooking. Roasters must be attentive to the beans just as the chef who cooks food to the highest standards. From the time the beans are struck by heat to various stages of roasting A good roaster is aware of what to do.
Be sure to do your homework prior to your roast.
A roaster must do his research before @!%G2A roasting commences. He must be aware about the beans he is about to roast down to the type, variety and the flavour notes it could contain. He will then be able to make a roasting profile that will emphasize the distinct qualities of each bean. It's now the time to roast.
Steps to roasting coffee beans, minute by minute
Drying takes between one and three minutes. This is the first stage of the roasting process. The coffee remains green at this stage. The coffee is taken and processed. It could comprise between 10-12 percent water. The moisture has to be removed before the beans are heated, which is typically done within three minutes.
Light brown to yellow (from 3 to 8 minutes). Changes in colour take place when the beans are stripped of all moisture and water. The beans' color changes from green to yellow to light brown. This is a sign that the sugars of the beans are reduced and their chemical composition has changed. There may also be a toasted or grassy grain aroma coming from the roasting drum.
First crack: Between 8 to 8 and a a half minutes. As heat pressure builds within the beans, the beans try to escape. The beans will explode when they crack the first time. The sound is a clear popping sound. You will also notice that the beans have expanded as heat is released. This initial cracking stage lasts only a few minutes since beans absorb and give heat away, making the roasting process essential.
Development (from eight and an hour to ten minutes). This stage is the most crucial in roasting. There are numerous chemical changes that take place in the @!%G2A and will greatly alter their flavor and scent. If the stage of development is prolonged the beans will become acidic. To hot and the beans will caramelize. It's up to the roaster's ability in determining the length of time the beans are allowed to grow, resulting in their distinctive roasting profiles.
Finalization of roasting. Once the roaster has finally reached the roast profile he wants, he will then quickly take the beans out of the roaster, and allow them to cool quickly.
De-gassing. The beans are allowed to de-gas for between 15 and 24 hours in a ventilated container. The bags are usually equipped with valves that only allow gas to escape. These beans are developed fully prior to being prepared for brewing.
