Steps of making Coffee in Mocha Pot Analysis of homemade coffee: mocha pot

The mocha pot is divided into three parts: the upper seat, the powder trough, and the lower seat. The lower seat is a sink for holding water, and the powder trough is used to hold finely ground coffee powder. The upper seat is to hold the extracted coffee liquid. When brewing, the water is placed in the lower pot and the coffee is placed in the middle of the net. when the pot is heated, it produces steam and rushes the hot water up. Pass through the coffee powder, then into the pot to form coffee. Because its air pressure is relatively high, some people classify it as high-pressure cooking. Some people call it hand-made espresso, but it can't make the foam of espresso. But it's really exciting coffee.

Steps for making coffee in a mocha pot:

Step one:

Hot water is injected into the lower seat of the mocha pot, and the water level must not exceed the lower edge of the safety valve. The safety valve is the limit of the maximum water level of each mocha kettle.

Cold water is not recommended, which will increase the time it takes to soak the coffee powder and make the extracted coffee bitter and turbid.

Step 2:

Filter paper can be pasted at the bottom of the upper seat.

This is a form of modern mocha pot making method. Ten years ago, the mocha pot was made without filter paper.

When sticking the filter paper, the filter paper should be laid correctly in the middle of the lower seat filter. In order to achieve a better fixing effect, the filter paper can be soaked with water.

Step 3:

Load the powder. This step is one of the important elements related to the cup effect of coffee (water volume, powder loading, extraction timing).

Many friends have made obvious mistakes in this step, which can be summarized as follows:

a. There is not enough powder. If you choose the highest water level in the lower seat, your powder should also be fully filled. Otherwise, with the lack of coffee powder, the taste of coffee will gradually fade.

b. Press the powder with a powder hammer. Many friends use the special powder hammer of Italian machine to press the powder trough of Mocha, which is a painstaking move. If the pressure is too tight and the coffee powder is too fine, the coffee will be difficult to draw. So the key to filling a mocha pot with real powder is to fill it as much as possible instead of pressing it tight. The powder can be injected in batches when loading the powder, and the edge of the powder trough can be covered as much as possible without leaving any gap.

When the coffee powder is full, tap the vertical table of the powder trough a few times to ensure that the coffee powder can be fully filled.

Step 4:

After placing the powder trough correctly on the lower seat, tighten the upper seat on the lower seat. You can twist it a little too much for safety.

Step 5:

Heat the properly installed mocha pot on the heat source. For ease of observation, I suggest boiling the mocha pot with the top open.

Soon the coffee liquid overflowed from the central metal column of the upper seat.

With the continuous extraction, the liquid level of coffee will rise gradually. When there is grease on the liquid surface, please be careful that the coffee extraction is coming to an end. When the color of the oil changes from dark to light, the heat source should be cut off immediately to stop the extraction, otherwise the coffee will be in a state of over-extraction.

In particular, you can't stop after the sound of "snoring". This kind of coffee may even have the taste of roasted rubber.

Step 6:

Qualified friends can prepare a towel soaked in cold water in advance and put it next to the heat source. When you finish step 5, put the mocha pot on the cold towel. This will greatly reduce the possibility of over-extraction of coffee.

Tips

The maximum service life of the sealing ring under the upper seat of the mocha kettle shall not exceed one year, pay attention to replacement. It's kind of like the rubber seal of a pressure cooker. If it is not replaced in time, there will be lax sealing and air leakage.

If the phenomenon of gas outgassing or water leakage occurs in the lower seat pressure reducing valve during the manufacture of the mocha pot, the thin metal sheet in the middle of the pressure reducing valve should be replaced in time, otherwise the pressure of the mocha pot will be greatly lost.
