Coffee roasting is much more than heating the green beans until they turn brown. Although people tend to give more importance to heating, tandem airflow with heating can only deliver the desired result.

So, you need to ventilate the room. Other than keeping the window open, you must get a fan to induce continuous airflow. Increase the airflow gradually as roasting progresses for a better yield. This will also ward off the smoke and chaff produced.

3. Maintain the roast profile

The style of roasting has a significant influence on the taste and flavor of the final brew. Generally, roasting temperatures of coffee beans vary from 180° to 250°C (356° to 482° F). The process requires twenty minutes maximum. You may adopt any of the followings:

  • Light roast: For this, roast the coffee beans for about seven minutes at 180° to 205°C (356° to 401°F). There will be a cracking sound and the beans will also be almost double of their original size. It delivers a weak and sour final brew.
  • Medium roast: You have to roast for nine to eleven minutes at 210° to 220°C (410° to 428°F). The beans will turn light brown with a drab exterior. It yields a balance of acidity, aroma, and flavor and makes an excellent final coffee.
  • Dark roast: This is for people who love a strong brew. You have to roast the beans for twelve to thirteen minutes at 225° to 230°C (437° to 446°F). Remove the beans after the second cracking sound. The final brew has a dense, full-body flavor with a spicy touch.
  • Extra dark roast: Roasting for about fourteen minutes 240° to 250°C (464° to 482°F). Roast till just before the beans tend to turn to ashes. This gives a bitter, strong and smoky taste.
