How to handle the size of water injection when making coffee by hand? How to master the direction and speed of water injection?

Uncle Coffee: when brewing hand coffee, it will first go through the steaming stage, the time is about 15 to 30 seconds, let the coffee powder absorb water, the coffee powder that absorbs enough water will expand, and produce another kind of aroma, the longer the steaming time, the stronger the coffee flavor, usually the amount of steaming water is twice that of coffee powder, for example, 30 grams of coffee powder, about pour 60cc water, so that the coffee powder can absorb enough water.

After steaming the coffee by hand, the action of water injection is carried out. it is generally recommended that beginners use a hand pot with a fine mouth, so that the amount of water injection is not too much and it is not easy to fail; at the beginning of water injection, it is easy to extract coffee, if you are an ordinary hand pot, do not use too much water at the beginning, and use a large water injection near the end to avoid flushing out too many impurities. The ideal time for water injection is about one and a half to two and a half minutes. If you want the coffee to taste thicker, you can slow down.

The direction of hand coffee injection can start from the center, around the outside of the circle to the clockwise direction, to remember that the biggest impact is not to rush to the filter paper. In addition, another technique when brewing coffee is to cut off the water, which is to interrupt the water injection process. This action can make the hand-brewed coffee taste not too heavy or too thin. For example, the water in 360cc can be interrupted at half the 180cc, and then continue to be injected until the water level on the coffee powder drops. This can adjust the flavor of the hand-brewed coffee and make it stronger. In addition, when the water column is too large, you have to cut off the water to avoid causing the taste to be too light, so you can change the taste of hand-brewed coffee and adjust the extraction rhythm by cutting off the water. It is recommended one or two times.
