1. The roaster signals you to add the beans at 75°C. Allow the device to heat up a bit more for this roasting and add the beans at 102°C. Now start your stopwatch.
2. The roaster tries to adjust the heat supply and the fan itself, as it follows a preprogrammed curve. However, you intervene and keep the heat at 100% and the fan at 0. Now you can relax a bit during the first approximately 7 minutes.
3. At around 160°C, you notice an increase in smoke. Now adjust the fan to 25%. But not more, as for this roasting, we want to quickly reach the first crack.
4. After about 9:30 minutes, the smoke continues to increase, and you adjust the ventilation to 50%, at the same time reducing some power from the heating element to 80%, as you approach the first crack.
5. After about 10:30 minutes and at around 182°C on the display, you hear the first crack beginning. Now you can reduce the heating element to 70%.
6. Half a minute later, at 11:00 and around 193°C, you further reduce the heating element to 50% and the fan to 75%.
7. Half a minute later, at 11:30 (around 196%), reduce the heating to 30%. Now the first crack is slowly ending.
8. One minute later, at 12:30 (around 200°C), increase the ventilation to 100%.
9. After 13:00 (around 203°C on the display), reduce the heating element to 20%.
10. Once your desired roast level is reached (or just before), press Eject to end the roasting process.
