Novice practice manual coffee notes illustrated manual coffee grinding powder coarse appropriate?

Making coffee by hand is not as difficult as you think, but many times, we only pay attention to the general direction of brewing, some small details are easy to ignore. And there are some details that determine whether a cup of coffee is good or not. The following is from the front street to tell you what details should be focused on.

Detail 1: The bean grinder can not make up for the front street. When solving the hand-brewed coffee problems of many small partners, it is found that the most problematic problem is the grinding degree. It is not that they are not sure about the grinding degree of the hand-brewed coffee, but that their bean grinder hardware is not up to standard. The coffee that comes out is weak or bitter, and it has nothing to do with the fineness of the grind. So, if you want to make a good hand brewed coffee, you can't save money on a good grinder. Good grinder standard: grind evenly

Details 2: Grinding is placed in the final step of the preparation stage. Basically, friends who use hand-brewed coffee know the importance of freshly ground coffee. After coffee beans are ground into powder, the flavor dissipates quickly, so the best practice is to grind coffee after preparing filter cups and other appliances.

Detail 3: Please carefully check several points that should be paid attention to before injecting water for your reference. Please check that the waste water in your pot is clean before filling it. When wetting the filter paper and warming the pot, the water stays in the next pot, sometimes forgetting to pour it out and flushing it directly. Even experienced baristas sometimes make these low-level mistakes, so pay special attention before filling.

After grinding the coffee powder, it is recommended to zero the electronic scale first, and then pour the coffee powder to confirm whether the gram weight is accurate. Beware of bean grinders "eating powder" without you knowing it.

Detail 4: The grasp of extraction time In addition to coffee grinding degree, it is the most difficult to grasp the extraction time, many small partners said, grasp the end time of water injection is very powerful, how can the free sedimentation of the remaining coffee liquid be controlled! In fact, after the grinding degree is grasped, basically the water injection method can affect the time. The first is the problem of segmented extraction. The more segments there are, the longer the overall extraction time. Therefore, one blade flow is shorter than three stages (15-20 seconds difference)!

Water injection with large water flow will also take shorter time than water injection with small water flow. Large water flow can raise the height of powder layer and dilute the thickness of powder layer at the bottom. Water injection will naturally be faster. Large water flow and small water flow can also be used alternately to adjust the extraction time. Generally, it is reasonable to control the brewing time from 1 minute 50 seconds to 2 minutes 10 seconds. Detail 5: After brewing coffee, please shake the pot. Under normal circumstances, the coffee that has just been brewed is not completely blended evenly, and it generally presents a strong and weak state. So you need to shake the pot to make the coffee blend evenly. One reason to use a cloud sharing pot is to make it easier to shake (actually, to look good).
