Roasting is the process of heating raw coffee beans to release their body, flavor, and aroma. During this process, the beans take on their characteristic brown color, decrease in weight, increase in volume, lose humidity, and, above all, acquire an aroma. The result is a coffee blend that expresses all of its sensorial properties.
