What temperatures are reached in a roaster device?

Coffee roasters can reach temperatures anywhere from 350°F (177°C) to 600°F (315°C). The exact temperature used depends on the type of coffee bean being roasted and the desired roast level.

* Light roast: 350-400°F (177-204°C)

* Medium roast: 400-430°F (204-221°C)

* Dark roast: 430-465°F (221-240°C)

* Extra dark roast: 465-600°F (240-315°C)

The higher the temperature, the darker the roast. Darker roasts have a stronger, more bitter flavor, while lighter roasts have a brighter, more acidic flavor.

The temperature of the roaster also affects the amount of time it takes to roast the coffee beans. The higher the temperature, the faster the roast. Roasting coffee beans at a lower temperature for a longer period of time will result in a more evenly roasted bean with a more complex flavor.

In addition to the temperature, the airflow and humidity in the roaster also play an important role in the roasting process. By carefully controlling these factors, roasters can produce coffee beans with a wide range of flavors and aromas.
