Hello Larsons uses a BC-15 roaster to roast all of their fresh beans powered by natural gas and electricity.
To begin the process, raw or green coffee is weighed, and placed in a holding chamber on the BC Roaster. The roaster must reach optimal temperature before the beans are released into the drum. As the batch begins, the beans are heated in a rotating drum that has constant airflow. The process and temperature are monitored electronically throughout the batch. We look for a steady curve to assure consistency and unwanted variations in the batch.
During each roast, there is a popping sound that occurs called first crack. In a simplified explanation, this lets us know the coffee is “done.” First crack signifies that the beans have released enough moisture, a suitable temperature has been reached, and the coffee is consumable. At this stage, the coffee would be considered a light roast. If the batch continues to roast, it will become darker, more uniform in color, and is called a medium roast. Second crack occurs after a few more minutes of roasting and a distinguished crackling sound occurs. If the beans reach the second crack stage, they are considered a dark roast also known as full-city. Each batch time varies, but most coffees roast for approximately 8 to 15 minutes dependent on preference.
After roasting, the beans are removed from the drum and released onto a cooling tray. Shortly after cooling, the beans are ground or left whole and packaged. Subtle flavor additives can be added to ground coffees right before packaging. Many other terms are used to describe these processes, but this is a quick overview of the coffee bean roasting process.
When starting to roast a bean variety, we experiment with what best compliments the natural flavors a variety already possess. Many factors change a roast profile including air flow, bean and air temperature, and drum speed. Coffee roasting is a craft that requires continuous learning.
