Coffee machine is an essential electrical appliance in modern life, and its extraction quality directly determines the taste and quality of coffee. However, many times we find that the taste of our coffee is not satisfactory, and sometimes there is too much extraction, which brings a bad taste experience. So what are the reasons why the coffee machine extracts too much?
1. Coffee powder is too fine
If the coffee powder is too fine, the water will be hindered when passing through, and it is difficult to flow, resulting in a slow extraction speed, which increases the water pressure, making the extraction strength too large and bitter taste. Therefore, when choosing coffee powder, you should generally choose the thickness that suits you.
2. Too much ground coffee
If the amount of coffee powder is too much, it will also lead to the insufficient circulation of hot water extraction, resulting in over-extraction. In general, the amount of coffee powder required for each brew should be controlled at about 10 grams, and the corresponding amount of water should be controlled at about 200ml.
3. The coffee machine entrance is blocked
If there is residue at the entrance of the coffee machine, it will also cause the coffee machine to extract too much after long-term use. When the coffee powder passes through the blockage, the water flow speed will increase, and the intact water will be forced to compress and extract too much.
4. Excessive water pressure
If the water pressure of the coffee machine is too large, it will also affect the taste of the coffee. This is because too much water pressure often makes the extraction time too long, and for some coffee beans, too long can also lead to poor coffee taste.
In short, the correct choice of coffee powder, control the amount of coffee powder, clean the entrance of the coffee machine and control the water pressure, in order to make the coffee extraction quality is appropriate and the taste is excellent.
