A brief introduction to the technical skills of using hand net to bake coffee beans at home

Hand net is also called manual roaster. The biggest advantage of hand net baking is that it can remove smoke, avoid the smoky taste of coffee, and make it easier to observe the changes in the appearance of beans during baking.

When baking coffee beans with a hand net, the firepower is fixed in a strong medium fire. After fixing the firepower intensity, the distance between the hand net and the flame is adjusted according to the firepower intensity.

The position of the hand net is parallel to the fire of the gas stove, shake it up and down slightly, and don't let the beans roll. Originally, there are many uncertain factors that will lead to failure in hand web baking. For example, because the wrist continues to shake the hand net at the same frequency, but after shaking for 20 minutes, the wrist will also start to lose rhythm because of fatigue, which can easily lead to baking failure. Of course, this is not the only variable that may cause failure, so it is convenient to find out other possible causes of failure by "fixed firepower" first.

Even if the firepower is fixed, nine out of ten beginners will still have uneven baking. The shape, size and moisture content of each coffee bean are different, and the method of shaking the hand net varies from person to person, and it always fails at first, but it is also very normal. on the other hand, even if the surface is somewhat uneven, as long as the heat can reach the center of the bean and make the bean fully expand. This kind of coffee is still far more delicious than some of the coffees on the market. The freshness of coffee is enough to outweigh the minor shortcomings in roasting.

To avoid uneven baking on the surface, moisture must first be removed. Raw beans will probably have inconsistent particle size, pulp thickness, water content and other conditions, as long as it is not the use of top-notch coffee, hand-selected steps can not be omitted. The differences in appearance such as color and shape are easy to distinguish, but the real difficulty is the difference in internal water content of coffee beans that cannot be seen from the outside.

Therefore, it must be assumed that all coffee beans have uneven water content, and some efforts must be made to remove moisture in order to eliminate this situation. When using hand net baking, it is particularly important to keep the hand net at a certain distance from the fire 10 minutes before the first burst, slowly overbake, let the water evaporate and eliminate the uneven water content.
