After drinking a lot of coffee, you suddenly find out why there is a big difference between the taste of the same bean when you drink it in a boutique coffee shop and when you make a coffee bag drip at home?
1.See grinding degree
The grinding degree of coffee powder in the coffee bag drip can determine the extraction efficiency of coffee. The thicker the coffee powder, the lower the extraction efficiency, and vice versa.
But the size of coffee powder in the coffee bag drip also has difference. Too thick coffee powder will lead to insufficient extraction, and it feels like drinking water. On the contrary, too fine coffee powder will lead to excessive extraction, which will make drip coffee hard to swallow.
There is no way to accurately judge this point before the first purchase. You can only watch the appraise of other buyers or try to buy less.
2. Look at the filter paper
Filter paper is actually a factor that is easy to be ignored. It can be divided into two aspects: "smell" and "smoothness of water".
If the quality of the filter paper itself is not very good, there will be a great "taste" in the coffee. This is usually what we don't want, and the way to avoid it is also very simple, just buy a reliable big brand.
On the other hand, the "smoothness of the water". If the water is not smooth, it will lead to a long time to wait for the second water injection after the lug water injection. The waste of time may not be the biggest problem. Excessive soaking will also lead to excessive extraction. On the contrary, if the water is too smooth, it may lead to insufficient extraction.
This is the same as the above. There is no way to accurately judge before the first purchase. You can only watch the seller show or try to buy less.
3. Pay attention to the water temperature when boiling
This is not a knowledge point about shopping, but it is a major factor affecting the taste of ear bags.
Generally speaking, the higher the water temperature of extraction, the more bitter it will be, and the lower the water temperature, the more acidic it will be. In fact, even after the completion of extraction, the coffee liquid will still produce a continuous taste change with the decrease of temperature.
Next time you can try how the taste changes when the temperature drops to 50, 40, 30 and 20 degrees after extraction.
