The main purpose of roasting coffee is naturally to create an aromatic coffee blend. Many professional coffee roasters say the roasting process is the combination of science and art.

The stages of roasting coffee

If you bought green coffee beans, now is the time to take care of them. The first thing to do is preheat your roaster. You should not place the beans in a cold drum as this can negatively influence your roast. Each machine is different and the temperature range may also vary. Preheat the drum. Recommended preheating of CMS coffee roasters – 200 degrees. You should get to know your machine well, so you can change settings whenever you need to.
Once the machine is ready, you can start the drying phase. Green coffee beans contain a lot of moisture. As they dry, the water evaporates, causing the beans to shrink in volume and weight. The beans must be dry before beginning the second phase, called caramelization or browning. The goal is to develop wonderful aromas, taste and change color from pale to brown.
You need to listen to what is happening during this step. The first crack has a characteristic sound – this is an important signal for you. As mentioned earlier, coffee beans contain water. When the temperature becomes high, the water inside the grains begins to evaporate. The pressure inside increases and that is why the coffee beans start to crack. You can develop fantastic flavors by slowing down the browning process. The second crack is quieter, so you have to be more careful. This is a sign that the oils from the inside have gone outside and your kernels have become even more developed.

The last step is cooling. You need to cool the coffee beans to room temperature within 3-4 minutes to complete the roasting process. We do this to stop the enzymatic processes as quickly as possible – the idea is to stop roasting at a time that we expect and control.
