Is it normal to have coffee grounds in coffee? Will the espresso powder bowl deform? How fine is the fine powder?

When we drink espresso, we can always see some black foreign bodies at the bottom of the cup from time to time, especially milk coffee, which will be more conspicuous because of the difference in color. Whether it is their own random production at home, or the rigorous processing of the coffee shop, these foreign bodies will appear at the bottom of the cup. So it makes people wonder what kind of existence they are and why they appear so frequently in coffee.

In fact, friends who have read the previous articles on Qianjie know that the true identity of these black foreign bodies is the very fine powder of coffee. And the reason why they can go through the hole of the powder bowl is simply because they are so small! So under the high pressure of the coffee machine, they can go straight through the hole and join the coffee. There are also types of mocha pots that are also extracted under pressure. And, because they are very fine, at first they are hidden in grease and float on the surface of the coffee liquid. As the grease bubbles break, they fall into the bottom of the cup when they are already saturated and are discovered by us. Therefore, this situation is a normal phenomenon! Although coffee powder is wood fiber, but very fine, very small amount of them will not have a bad effect on the human body at all, so you can rest assured to drink.

Not only that, as Qianjie used to say, the right amount of ultra-fine powder can increase the overall alcohol thickness of coffee. Of course, the fine powder will be accompanied by a certain bitter taste, so if we do not want the bitter taste, it is also very simple to remove the fine powder. Just add 1'2 pieces of round filter paper to the bottom of the powder bowl to solve this problem as much as possible.

Just when everyone is about to announce End happily, I believe you will find that it is not so simple. After all, the progress bar is only halfway there! In front of the street, it is said that the fine powder "exists in the right amount". But if we see a lot of fine powder from the bottom of the cup, such as the picture on the cover, it is not a normal phenomenon!

The existence of such a large amount of coffee powder will not only make the coffee taste more bitter, but also very affect the overall taste, resulting in very rough! In serious cases, it appears as the title: the bad experience of taking a sip of coffee and half a mouthful of dregs. There are two reasons for this. Let's talk about low probability events first.

Small probability event: the hole deformation of the powder bowl when the powder bowl is used with high strength for a long time, it will easily lead to the phenomenon of hole deformation and enlargement. When the hole of the powder bowl becomes larger, more fine powder will be able to pass through, which eventually leads to the emergence of this phenomenon. We can observe whether there are any individual deformations by pointing the powder bowl at the light source.

But as Qianjie said, the probability of such a thing happening is extremely small! After all, the powder bowl is very strong, and it takes a very high strength and a very long time to deform. The most common cause is health problems!

High probability event: if the head is not washed in time, not all coffee powder will be cleverly stuffed into the powder bowl, when we are negligent or the operation is not standard, some coffee powder will be attached to the handle or the edge of the powder bowl!

These coffee powders will appear in two directions after we put the handle buckle on the head, one is directly adsorbed on the edge of the water distribution network! When the coffee powder is adsorbed on the edge of the water distribution network, we can't wash it down by releasing water. instead, we need to use a special cleaning brush to remove it. If it is not cleared in time, the coffee powder will fall into the coffee the next time the handle is clasped.

Another trend is that when the buckle handle, the coffee powder attached to the handle will fall directly into the cup because of the vibration caused by the buckle! Because the particles are so fine, they will not be found on the spot. But because of the excessive quantity, it will affect the perception and reduce the drinking experience of coffee at the same time. So in cases like these, the solution is also very simple! We only need to pay attention to hygiene when making coffee and clean the coffee machine in time after the extraction is completed, so that the fine powder falling into the cup can be greatly reduced. Of course, washing one by one is very troublesome, so we can appropriately lengthen the "cycle" of cleaning, such as listing the rule of cleaning the coffee machine after several concentrates. Anyway, you can make it by yourself. as long as it is cleaned in time, there will be no half-mouthed coffee residue.
