Introduction of three-knife flow extraction of Qianjie-hand Coffee

The brewing methods of coffee are as follows: French pressure pot, siphon pot, hand flushing, etc.

There are many different ways to allocate water when injecting water. The simplest thing is to finish the water injection at one time and then wait for the filtration to be completed. For immersion extraction, this is the recommended method of water injection, which ensures that coffee powder and water molecules come into contact at the same time (the shorter the time difference, the better).

For hand-brewed coffee, because the water seeps through the coffee powder and flows out slowly, you can use continuous or intermittent water injection. Continuous water injection requires special attention to control your water injection rate; intermittent water injection refers to the use of multiple small amounts of water injection.

This method helps build the powder wall attached to the edge of the filter paper without being broken, and water injection helps the coffee powder stir during brewing: the water gently touches the coffee powder to make them move. make sure the coffee powder is in full contact with the water molecules. The relationship among water injection, coffee powder movement and extraction was established.

Every time you inject water, you can choose to draw a circle to inject water in a concentric circle, or to inject water at a fixed point. Different ways of water injection will make the extraction rate of coffee different, circle water injection will help coffee powder more uniform stirring, so that all coffee powder remain moist.

Step-by-step water injection can determine the extraction time. In the case of a certain total amount, to reduce the number of water injection, it is necessary to increase the amount of water injected each time, and to increase the number of times, it is necessary to reduce the amount of water. The number of times of water injection is less, and a large amount of water will make the coffee powder bed under greater pressure, which will also shorten the extraction time, while more times of water injection can prolong the extraction time.

The segmented concentric circle method can lead to more uniform extraction, but this requires a high degree of consistency. When you are doing hand flushing, it is almost impossible to get the same smell every time. Only a small number of people can guarantee such control.

Knowledge point: it is richer than a knife stream, and it can clarify the flavor of the front, middle and back of the coffee. The method is to increase the amount of water injection each time after steaming, usually when the coffee liquid is about to drop to the surface of the powder layer, and use small, medium and large water flow to do three-stage extraction.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
