Powder content of Espresso

However, in the daily situation, it is necessary to adjust the response according to the characteristics of Doudou, the characteristics of machinery, the thickness of grinding and so on. In the end, what only has the above data is a cup of coffee, but it is not necessarily a perfect Espresso, because coffee needs more enthusiasm to sublimate.

In some large espresso chains, when you see their bar quickly building a cup of Espresso, the action of baking powder is as simple as a click or two. In some traditional coffee shops or competitions, we often see different pulverizing actions-using a "hand knife" (that is, the edge of the palm to scrape off the excess powder), "finger knife" (the name means to scrape off the excess coffee powder with the belly of the finger, usually with the index finger), and scrape the powder with the edge of the powder cartridge lid.

In fact, all these actions have their own reasons:

For example, in a good business store, it is bound to enrich the powder bin and set the amount of doesing to 7.5g or 8g per box, so Barista can quickly get the right amount of coffee powder when building a beverage, and because the beverage is so popular, it has already turned into a cup of Espresso before the coffee powder flavor disappears.

So almost every time the remaining coffee powder is scraped, the amount of coffee powder has its own advantages, so after passing the test, I choose to give it up.

Using the "powder bin lid" and operating the original Radian of the powder cartridge cover, we will certainly be able to get 8.5 grams of novel coffee powder after a few more drills. In this way, we don't have to worry too much about the amount of powder.

Here is a picture of the test:

What is a cup of Espresso?

The results of the three tests are not beautiful, all with a scale of 8.5 coffee powder.

However, in other methods, the amount of powder measured is too biased, so the experiment proved that in order to obtain a uniform amount of coffee powder, Dosing Up's powder scraping method is simply desirable.
