Last Updated: 2024/11/08, Why does the coffee machine put water before extraction-the main reason is that every time it is boiled and ground, the coffee powder will completely oxidize after being exposed to the air for a few minutes, and the brewed coffee will not be able to drink. Now some coffee shops are used to filling up their dispensers, which is not correct. The right thing to do is to quickly pull the component lever while grinding the powder, turn it off when the handle is almost full, and continue to pull the component.

Every time it is boiled and ground, the coffee powder will oxidize completely after being exposed to the air for a few minutes, and the brewed coffee will not be able to drink. Now some coffee shops are used to filling up their dispensers, which is not correct. The right thing to do is to quickly pull the component lever while grinding the powder, turn it off when the handle is almost full, and continue to pull the lever until all the coffee powder in the meter falls into the brewing handle.

The water must be cold water or warm water. @ DimLau said in the answer that adding 90 degrees of hot water is problematic. I tried to extract it with hot water heated by the water cooler, and it tasted terrible, bitter and astringent. In particular, that kind of acerbity is obviously a feeling of over-extraction.

Be sure to use filter paper. Although the machine has its own filter, the effect of this filter is difficult to guarantee. Coffee without filter paper is not only light in color and taste, but also contains a certain amount of particles in the filtrate, which makes it taste very bad.

It's no use putting in more coffee powder. This is also the conclusion of my own experiment. I even used the amount of one cup of water to extract four cups of coffee powder, and the results showed that the taste of the extracted coffee was not much different from that of the normal amount. If you put water and coffee powder in proportion, there will be no problem.

It is true that the amount of one or two cups extracted will be a little lighter than five or six cups at a time.

Finally, I think it must be painful to transfer from instant coffee to drip filter pot. On the one hand, the American pot is really light, and this is the characteristic of the machine, which cannot be improved by other methods; on the other hand, it is not used to drinking American coffee. if you don't add sugar or milk, it really tastes like traditional Chinese medicine.
