What does the cleanliness of coffee refer to? Which coffee beans have better cleanliness?

Now the first impression of a cup of coffee is often the most attractive flavor with a high degree of recognition. But the cleanliness of a cup of coffee is also very important.

What does clean coffee do?

A clean cup of coffee, Qianjie believes that there is no miscellaneous smell, defective smell. And it is clear and thorough. Miscellaneous smell and defective smell generally refer to the generally recognized bad taste. Imagine that you don't want to drink dirt, wood and rubber in your coffee.

Clarity and thoroughness, of course, means that the coffee you drink is comfortable and the taste of the coffee can be clearly felt at the entrance. For example, although some coffee does not show a defective flavor, but its flavor is vague and difficult to distinguish, giving people a sense of turbidity, which is also a sign of lack of cleanliness.

Cleanliness has something to do with concentration?

There seems to be a concept that light coffee generally shows good cleanliness. This seems to be true, but it is not entirely true.

As mentioned earlier, a clean cup of coffee is flawless, miscellaneous, clear and thorough. The angle used for cup testing is to test the quality of coffee beans, that is, the poor quality of coffee beans caused by external pollution or human errors in the process of coffee planting, harvesting, treatment and roasting.

Of course, the coffee beans we buy are all checked by bean hunters and bakers, and the quality of coffee beans is generally the first echelon. Therefore, we should pay more attention to the last link-- cooking.

① beans that are too fresh tend to feel dry, which can also affect the cleanliness of a cup of coffee; coffee beans that are not fresh can also affect cleanliness.

The reason why ② often feels cloudy is due to the excessive stirring during water injection or the bitterness of the local process caused by too much fine powder caused by uneven grinding of coffee powder.

But on the other hand, it also appears that the flavor has become light and watery, so that this cup of coffee will not give you a pleasant experience.

So, how can we make clean coffee?

① raise beans

As mentioned before, coffee beans that are too fresh will feel "dry". This is the choking smell of smoke left inside coffee beans after being roasted at high temperature, which takes a period of ripening and carbon dioxide emissions to remove, so leave it for a few days during the bean growing period. you will find that the taste is clean and the flavor highlights.

② pick beans

It is still necessary to pick beans before cooking, although there are layers of checks after raw bean processing and roasting, some slightly defective coffee beans will be ignored, and removing these defective beans will also reduce the risk of foul smell. As for how to choose, this can follow the heart, pick out the unpleasing ones.

③ avoids overextraction

Over-extracted coffee will not be cloudy for long, because some bad substances are brought out, bitterness and miscellaneous taste are inevitable. High water temperature, fine grinding of coffee, strong mixing of water injection and so on will cause the emergence of extraction.
