Last Updated: 2026/04/01, Coffee hand fixed point injection method analysis and cloth powder correct method introduction through the above three points, we can see that if the whole coffee noodle is injected with water, the upper end of the bowl, near the cup wall, if water is injected there, the water will only pass through a small part of the coffee powder, and reach the cup wall, ooze filter paper, flow down the cup wall, flow directly out of the cup, and this part of the water will be lighter, while in the middle.

Through the above three points, we can see that if the whole coffee noodle is injected with water, the upper end of the bowl, the part close to the cup wall, if injected there, the water will only pass through a small part of the coffee powder, and reach the cup wall, exudate filter paper, flow down the cup wall, and flow directly out of the cup, and this part of the water will be lighter, while the water injected in the center will be extracted more fully because it passes through more coffee powder honeycomb structure. So the taste is also strong. The taste of coffee depends on the soaking process of coffee powder in water, that is, the coffee powder is fully soaked and the taste is strong, but if the soaking is not enough, the taste is relatively light, so the water storage capacity of the brewing tool is an important factor. Flannel has a stronger water storage capacity than filter paper, so the flavor of flannel is stronger than filter paper extraction.

As you can see from the video just now, not to mention the performance of the flavor, this method of production is very slow to inject water, so it is also jokingly called intravenous drip. Many old masters spend years practicing and inevitably make mistakes in the production process. And it is very wasteful of energy and physical strength. If it is used for business to order more than a dozen cups continuously, it is also a great test for the producer.

From a personal point of view, Didi Water injection is really the most unstable, unreliable and magnified way to make it in the industry. Suitable for your own play, but not suitable for business.

In fact, each school is not difficult to master, it is just a combination of all kinds of data, what is needed is to master the principle of extraction and know how to match it will lead to what kind of result, so whether I teach or share, I will decompose the characteristics of various schools and combine the principle of each school with the principle of extraction.
