Last Updated: 2026/03/28, Do-it-yourself, the biggest advantage of roasting coffee beans with a hand net is low cost, fresh, even if it is not guaranteed to be very uniform. In addition, the firepower can be adjusted freely to facilitate the observation of bean color changes, which is also one of the reasons why coffee lovers are keen on this method.

It is also baked in a pan or Chinese frying pan, but it usually has the following disadvantages:

1. Heavier, it will be more difficult for the arm to keep shaking for a long time.

two。 The silver skin is easy to stay on the surface of the pot, so it is not suitable to judge the color state of beans.

3. It is not easy to tumble, resulting in uneven baking.

Here is one of my baking notes, and the main points are all above. However, the biggest point is to put it into practice, hehe ~

Utensils: there is a hand net, gas stove, hair dryer (used to blow off the silver skin after baking), clock.

The time will vary depending on the variety of beans, if you want, you can write down the time of beans at different degrees of baking for comparison.

With regard to the end of the baking, it is appropriate for the beans to be fully expanded, and there will be astringency if they are not baked thoroughly.
