Learning The Secrets About Coffee

The Elements in Coffee Roasting To be able to produce coffee, it starts with green coffee beans, soft spongy beans that smell like grass, which are thoroughly dried and later roasted and brewed to come up with an aromatic, flavorful drink. When roasting the green coffee beans, the gradual building up of heat helps in causing chemical changes to take place in the beans, such that when the desired temperature is reached, the beans are in a roasted appearance and a roasted aroma is emitted which is uniquely characteristic of coffee. Non-roasted coffee beans contain levels of amino acids, protein, sugars and caffeine, a stimulant which is linked with the central nervous system, but when roasted, a Maillard reaction takes place, which is a chemical reaction between amino acids and sugars take place, and, thereby, resulting into a browned, roasted beans with a distinctive flavor. Roasting coffee is a mastery of having the ability to know when the beans are roasted to give that aroma and flavor and not burnt. Only coffee masters know how to produce the four categories of roasted coffee – light, medium, medium-dark, and dark. The same wonderful coffee aroma comes out of all these kinds of roasted coffee; however, it is in the flavor that each possess a distinct taste.
