Why Do Beans Split and Blow Out During Roasting?
When you roast coffee beans, they often split and sometimes even blow out, and this happens because of the rapid buildup of pressure inside the beans. As the beans heat, moisture inside turns to steam, causing bean expansion. This expansion pushes against the shell, which can crack under the pressure. Shell cracking is a common sign that the bean is reaching an unstable stage in roasting. When the pressure becomes too great, the bean’s outer layer can split suddenly, releasing built-up gases and causing a blowout. Factors like uneven heating or high moisture content can increase the likelihood of these splits. Understanding these processes helps you control the roast and minimize unwanted blowouts, ensuring a smoother, more consistent roasting experience.
