How do you make espresso? What are the skills of powder cloth? What are the steps of Italian concentrated powder?

The first basic action of making Italian coffee in the last issue [details are technology]: it is said in the powder connection that the powder connection is the first action of the powder distribution, so today, the small editor will talk about the action after the powder connection_powder distribution.

Cloth powder, in fact, is in the coffee powder after grinding, the coffee powder manually into the powder bowl and make it evenly distributed process. The most important thing in this step is to be uniform (not flat).

To say that the barista's daily operation, the powder distribution movement can be described as a variety of dazzling, so that all kinds of powder distribution artifacts came into being, what powder ring, powder cup, powder distributor, powder hammer cloth foundation...

As the saying goes, there is only demand for business opportunities. The rapid development of powder distribution aids is naturally due to the defects and deficiencies of powder distribution technology. However, even if it was the most advanced powder distribution artifact, it still could not completely solve the problem of powder distribution errors. From this, many people can't help but sigh: this kind of work of cloth powder is really metaphysics_

Let's not discuss metaphysics first. Today, I want to explain to you several major sects in the method of cloth powder, and analyze the advantages and disadvantages of various methods.

1. Scraping flat cloth powder method.

There are three sharp tools for scraping flat cloth powder: powder bin cover, bamboo chips and fingers. It is rumored in Jianghu that experts can control the amount of powder at will by using the powder bin cover, which has two unique skills of "flat scraping" and "concave scraping"; using bamboo chips will make espresso have fresh plant smell; experts using fingers are even more powerful. When the unique skill of "One Yang Finger" is practiced to the great extent, the internal force can instantly disperse the agglomerated powder. With a flick of a finger, the powder will not stick to the finger.

Ahem-that's bullshit.

Scraping cloth powder method is one of the most common and earliest contact methods for novices, usually with back and forth push and other actions, and divided into front and back scraping left and right "square cloth powder", 360 degrees rotation scraping "rotary cloth powder" and so on.

Scraping powder method seems professional, in fact, the effect is not big, the process of wiping may produce uneven pressure, and the smoothing is always only the surface part of the coffee powder, the lower layer and the edge of the coffee powder is still randomly distributed, after pressing the powder, different parts of the powder density is different. Simply by scraping flat cloth powder, extraction will not be perforated, this depends on the character.

Second, tap lightly knock cloth powder method.

Tap and tap are two actions, but they are usually used consecutively. Palm quickly tap the bottom of the handle, shake the powder pile evenly, supplemented by straight up and down light knock, can effectively eliminate the large gap in the powder layer, make the coffee powder pile more dense, at the same time increase the powder bowl can accommodate the amount of powder.

The use of light tap cloth powder method experts, can keep the hands clean to the greatest extent, reduce the operation steps, common in various barista competitions, with baristas clean movements, smooth and refined, but for the technical proficiency requirements are high, without special training, ordinary people are difficult to achieve satisfactory results in a short period of time. Moreover, the flatness of the surface of the light knock powder is poor, which may make some "obsessive-compulsive" baristas feel that the effect is not as good as the scraping method, but in fact the uniform effect is much better than the scraping method.

Third, auxiliary equipment powder distribution method.

When it comes to assistive devices, naturally they also show their magical powers. According to the various artifacts on the market, there are mainly several types: ① stirring or shaking;② smoothing the surface;③ sieve dispersion;④ rotating distribution.

Most artifacts can achieve the effect of mixing coffee powder, breaking up clumps, evenly distributing particles, etc., but there are also defects: waste coffee powder, complicated tools, certain skills required for operation, more pressure when distributing powder, which may lead to internal cracks, only smooth surface, distribution and thickness cannot be guaranteed, etc.

In short, assistive devices are not omnipotent, and relying too much on assistive devices is not good for the barista's own brewing understanding and technical improvement.

Powder effect check

During the extraction process, if it is found that the state of coffee outflow quickly becomes unstable, the color jumps greatly, and the color quickly becomes very light, then it can be judged that there is a problem inside the powder cake (cracks appear) or the uneven powder pressing makes the coffee powder less part be over-extracted (and this is also likely to be uneven powder distribution) or the powder distribution is uneven, so that the edge is not covered by coffee powder, resulting in water flowing directly from there.

After extraction, remove the handle and observe the shape of the powder cake. If there is no coffee powder at the edge, or the coffee powder is soaked, the powder cake has obvious gaps, etc., it is because the powder is not evenly distributed.

last

The ultimate goal of powder distribution is to evenly distribute coffee throughout the powder bowl before pressing, not only on the surface, but also on the inside and edge of the powder bowl. This step will directly affect the stability of your coffee extract, if you want to get a cup of qualified Espresso, do not ignore this step.
