When it comes to ways to adjust the flow rate of coffee, many friends may think of the degree of grinding as soon as possible. Fine grinding can delay the draining time of coffee, and coarse grinding can increase the draining speed of coffee. This is true. But in addition to the degree of abrasion, there are many ways to adjust the flow rate, such as the instruments we use, or the way we brew... So today, Qianjie came to share with you, in addition to the degree of grinding, what other ways to adjust the flow rate of coffee by hand.

1. The relatively simple method of segmented water injection is to inject water in multiple segments! Qianjie also often shares it in the article that segmented water injection can increase our extraction time, because there will be many waiting intervals during the segmented process. In addition, segmented water injection will also reduce the amount of water injected in each stage, which will reduce the water pressure in the filter cup, thereby slowing down the infiltration of coffee liquor.

Therefore, segmented water injection is a good way to adjust the flow rate. When you want to adjust the flow rate when you cannot adjust various other parameters, try water injection in stages. The more paragraphs you have, the longer the extraction time will be, and vice versa!

2. Water flow size The second plan is also operational, that is, controlling the flow rate of water injection. You can try it. Different water injection flow rates will have different extraction times. The faster you add water, the shorter the coffee extraction time will be. Conversely, the slower the water injection rate, the longer the coffee extraction time will be.

3. Replacing the filter paper It is also a good solution to adjust the flow rate by replacing the filter paper. As we all know, the difference between filter paper and filter paper is as big as the difference between humans and orangutans! Filter papers of different materials will have different flow rates and effects. Even with the same material, different production processes will make earth-shaking differences in flow rates, so filter paper is also divided into different versions of "fast flow rate" and "slow flow rate". If you want to adjust the flow rate, replacing the filter paper used is also a good solution.

4. Replace the filter cups. Of course, when there are enough filter cups, we can also adjust the flow rate by replacing the filter cups. Different filter cups will have different drainage speeds due to differences in design. For example, Qianjie uses different filter cups when brewing coffee beans of different degrees of roasting. The purpose is to adjust the flow rate while fixing other variables.

It is actually very simple to know the flow rate of the filter cup. We only need to look at the design of the inside of the cup wall and the bottom hole. The longer, more and more prominent the diversion ribs on the inner side of the cup wall, and the more the number and diameter of the bottom holes, the faster the drainage speed of the filter cup, and vice versa, the slower it will be. The filter cup used by Qianjie when brewing coffee beans with slow water discharge speed is V60. It not only has a large number of diversion ribs, but also has a large diameter bottom hole, which makes the water discharge speed very fast. Here, take the former street grana rose summer in the former street bean list as an example.

Qianjie Grana rose summer is a medium-to-light baked native rose summer in Ethiopia. It not only has rich fruit flavor, but also has a very high value for money. When cooking with V60, the parameters that Qianjie will use are as follows: powder amount 15g, powder and water ratio 1:15, grinding degree 75%~80% of sieve rate of No. 20 sieve, 91°C~93°C brewing water temperature, three-stage brewing, extraction time 2 minutes.

If the coffee beans that are roasted deeply or drained quickly are brewed on the front street, the filter cup used will be a slow-flow Kono. Here is a share of the world-class deep-roasted coffee representative of Qianjie PWN Golden Mantelin in the previous street bean list. Front Street PWN Golden Mantinin can be said to be the top representative of Mantinin. The flavor when it is deeply baked not only has strong aroma of chocolate, nuts and caramel, but also has a very mellow taste and strong sweetness. When using a Kono filter cup to brew it, the parameters used by Qianjie are as follows: powder amount 15g, powder and water ratio 1:15, grinding degree 70%~75% of the sieve rate of No. 20 screen, 86°C~89°C brewing water temperature, three-stage brewing, extraction time 2 minutes.

So the above is all the content shared by Qianjie this time! Of course, there are many ways to adjust the flow rate, such as using certain brewing toys to change the structure of the powder bed. Everyone can study it slowly by themselves. There are many ways to play, not only limited to one kind of grinding degree ~
