When the bean temperature reaches 165 °C (329 °F) the roasting begins. It takes about 8–15 minutes to complete roasting. After cooling, the beans are then ground finely. Grinding reduces the beans to 0.5-to-1.1-millimetre (0.020 to 0.043 in) pieces. Until here, the process is in general the same as for other types of coffee. [18]

Although the beans experience a weight loss, the size of the beans double during the roasting process due to the physical expansion caused by an increase in internal pressure from vaporized water.
