First Crack

Sound is a great indicator for the roasting temperature. There are two points within the roasting process where what you hear becomes very important. These audible moments are called “cracks”. The first crack of the coffee bean comes at about 385°F in the roasting process. Hearing this first crack lets the roaster know his coffee has reached the beginning stages of “light roast”.

Coffee cracks? Coffee beans contain moisture, and when the heat of the roaster causes that moisture to evaporate, the bean will expand and crack.
