Coffee is a brewed drink, which is loved all over the world and in time memorial for its flavorful aroma, which is produced from drying and roasting green coffee beans.
Roasting coffee brings out the aroma and unique flavor of coffee which is locked inside the green coffee beans, as the heating process allows the transformation of the chemical and physical properties of the green coffee beans to produce coffee. Levels of organic compounds, such as amino acids, protein, sugars and caffeine, a stimulant which is linked with the central nervous system, are contained in green coffee beans and when these beans are roasted a chemical reaction takes place, which is known as the Maillard reaction, which is a chemical reaction between amino acids and sugars, and this reaction produces brown, roasted beans that possess a distinct aroma and 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. All categories give that aromatic smell but the flavor of each differs.
