It is a process that requires precision as the method involves the techniques of art and science as you need to manipulate time, heat and other factors. This process is usually carried out by skilful coffee roasters who transform green coffee beans into rich and aromatic beverages that everyone enjoys. If you are wondering how coffee roasters craft the perfect cup of coffee for you, then make sure to read this ultimate guide on the science of roasting.
Coffee beans are green; coffee roasting is a process where these green beans are manipulated with heat to develop a certain kind of aroma, flavour and colour in the beans. When the roasters heat the beans, they release moisture which causes them to expand and develop a brown colour due to various chemical reactions. The roast levels and aroma can vary depending upon the techniques used while roasting, like the level of heat and the time for which the beans are roasted.
The flavour profile of roasted coffee greatly depends on the roast level. Roastes need to be careful while roasting the coffee to control its aroma, colour and flavour. Light roasts include fruitier notes that are high in acidity, which gives the beans complex flavours. Medium roasts are more balanced as the acidity and body are of equal levels due to profound sweetness and caramelisation.
Dark roasts, unlike light roasts, have lower acidity with heavier bodies. The aroma is more intense and has a smokey flavour due to prolonged exposure to heat. To choose the right level of roast, extensive knowledge of green coffee beans and the process of roasting is required.
Roasting equipment and techniques vary on the basis of their consumption. Small home roasters are available for domestic use, and commercial machines are available for commercial purposes. As for the techniques, there are hot air roasting, drum toasting and fluid bed roasting.
Each technique is unique and offers different kinds of benefits. The sole purpose of the roasting technique is to apply heat evenly to the coffee beans and control the whole process of roasting effectively for the best results.
