Multi-person hand-brewed coffee making method how to brew black coffee powder

Recently, Qianjie received such a share: "I usually use your V60 filter cup, and the coffee tastes good when I drink it myself!" But as soon as a friend comes to the house, I'm going to roll over when I'm about to show my skills. The proportion of powder and water is all the same! Just put more coffee powder to make more coffee at once, how can there be such a big difference in taste? "

The filter cup has a limited load! Qianjie daily products mostly use V6001small filter cup, which is suitable for brewing coffee for 1-2 people. The recommended powder dosage for this type of filter cup is 13g-20g, and the best powder dosage is 15-17g.

In the process of water injection, coffee powder will be evenly distributed around the cup wall with the rise of water level to reduce the thickness of the powder layer and make coffee extraction more uniform. If the amount of powder is too small, there is not enough coffee powder evenly distributed on the cup wall, and some water flows directly along the cup wall into the next pot of diluted coffee liquid without extracting the coffee material, and finally the coffee tastes insipid. If the amount of powder is too large, the filter cup does not have enough area to allow the coffee powder to be evenly distributed on the cup wall, which will cause the powder layer to be too thick and prolong the flow of water through the coffee powder, resulting in an unpleasant astringency in the coffee.

(above, 10g coffee powder. Below, 25g coffee powder)

be fully prepared to

It is suggested that the maximum powder dosage of V6001filter cup should be 20g.

Under normal circumstances, 20g of coffee powder is brewed at 1:15, and the weight of the final coffee liquid is about 275g. It is enough for 3-4 people to share it. It is not enough to make coffee again. You can't force it to make coffee. If it is often shared by many people, Qianjie recommends buying a large filter cup # 02, so that there is enough space for the coffee powder to be evenly distributed, and the sewer hole will increase accordingly to reduce the excessive extraction caused by blockage.

It is also a trick to boil 20g powder with V6001filter cup! Do not directly quote the cooking parameters of 15-17g powder! Due to the increase in the amount of powder, the thickness of the coffee powder layer is bound to increase, and the passing speed of water will slow down. In order to avoid excessive release of coffee substances caused by the increase of extraction time, we need to adjust the degree of grinding and brewing methods!

"Adjustment of grinding degree"! Since the flow channel becomes narrower due to the decrease of the space between coffee particles due to the increase of coffee powder, we can thicken the grinding degree a little bit to increase the gap between the particles. That's for sure! We can't thicken it by a big margin. Take the medium and shallow roasted coffee beans as an example, Qianjie uses the China 20 standard screen screening rate of 80% (fine granulated sugar thickness) when brewing 15g coffee powder every day, and if you brew 20g coffee powder, the screening rate of Chinese 20 standard sieve can be used (75% between fine sugar and coarse sugar).

"adjustment of brewing method" if you follow the same small flow of 15 grams of powder (4G per second), even if the coffee is ground a little thicker, the extraction time will still be too long. In order to reduce the coffee concentration caused by excessive release of coffee substances, you can use medium water flow to inject water (6g per second). On the premise of increasing the flow, it is still necessary to maintain the vertical injection of water, otherwise it will easily lead to uneven extraction.
