Roasting is the briefest yet most important and painstaking stage in coffee production. This process carries a heavy weight of responsibility. Both time and money can be lost in a brief moment of carelessness, rendering the labour of hundreds of people on the fields and in the production process pointless.
The heat applied to the green coffee beans during roasting changes their colour from the original light green to brown. As the heat rises, the beans lose water. Before roasting, the green coffee beans have no aroma or fragrance; the roasting process uncovers over 900 aromas hidden in the beans.
Not every variety of coffee is roasted in the same manner. This is what makes roasting an art form. It requires experience, knowledge and expertise accumulated over many years. An experienced roaster knows the limits and potential of a given type of coffee. It is only through this skill and experience that the roaster is able to maximise the quality of the coffee.
