Filter paper brewing is very suitable for coffee lovers, because it integrates coffee grinding, coffee extraction, and coffee products, so that people can have a deeper understanding of coffee in these aspects.
For novices, filter paper brewing is still difficult to operate. Because it takes more time to brew coffee of stable quality through this method, and requires repeated practice. The process needs to pay attention to the following points:
Control the extraction time
When using the filter paper brewing method for hand brewing, it is important to note that: because the injection of hot water and the filtration of the coffee liquid are synchronized, the extraction time is not easy to control, and there is no fixed reference time. But the extraction time is an important factor in determining the taste of coffee. Therefore, no matter how many times hot water is injected during brewing, it should be noted that the total time should not exceed 3 minutes! After more than 3 minutes, the brewed coffee is weak and bitter. At the same time, because the extraction time is too long, bad tastes such as astringency in the coffee will be precipitated together, which will affect the taste of the coffee.
Reasonably adjust the extraction time
When brewing, the amount of coffee powder will affect the extraction time. When the amount of coffee powder is small, the contact area between hot water and coffee powder will be large, and the extraction time will be shortened accordingly, so that the coffee flavor can be reflected. When the amount is large, the extraction time should be increased, because the amount of powder increases, and if the extraction time remains the same, some soluble substances in the coffee cannot be precipitated, which will result in a weak coffee taste and a thin taste.
For example, when the piston or siphon brewing method increases the number of brewing cups, you only need to increase the amount of coffee powder and water in multiples to brew the same flavor of coffee. But the filter paper brewing method cannot use this method. In order to change the taste, you can use coarsely ground coffee powder, so that the extraction time will be shortened, and the taste of the brewed coffee will naturally change. If you do not change the thickness of the coffee powder grinding, you can also change the taste by adjusting the water temperature .
Adjust the extraction time according to the filter cup
Different coffee filter cups have different extraction times. Different coffee filter cups have different extraction speeds due to factors such as caliber and size, which also affect the taste of coffee.
