In the second stage, many changes are happening with the beans their color starts to get dark. In the second stage aroma of the coffee beans starts to spread in the air and the beans are going through the Maillard reaction

The third step is also called the light roast step if you stop the roasting process after this step then the beans would be lightly roasted. In this step, the beans are roasted and they start to break from the middle and become a bit puffy. The sound of coffee beans splitting from the beans is audible in this stage.

This is the last step of heating the coffee beans and in this step, they start to crack again same as the popcorn. The bean which we get after this stage is called the dark coffee beans. The internal oils of the coffee beans start to creep out from the inner shell of the bean through the second crack. The bean we get after this process is dark brown and has less acidity.
