The skill of preparing Coffee granules in Fine Coffee Science

The Italian coffee machine uses pressure to quickly pass the steam through the coffee particles and extract the best ingredients from the coffee, so the time for the steam to stay in the coffee particles directly affects the quality of the coffee.

Operation steps:

Step 1 scoop the coffee particles into the coffee filter cover, observe that the coffee exceeds the level of the lid, and cut off the excess coffee particles with a flat knife or spoon.

Step 2 knock the coffee filter cover so that the coffee particles are evenly distributed, which is why the better Italian coffee machines use heavier metal to make the coffee filter cover. Because if it is other materials, it may not be able to withstand too many heavy knocks.

Step 3 use a pressure bar to filter the coffee particles in the lid. In the pressure of coffee particles, it is best to maintain the level of coffee particles, otherwise the steam will be uneven, it is best to use the muscles under the thumb to press, it is easier to apply force evenly. And how much pressure does it take, you can try it several times. The important thing is to try the same batch of coffee particles several times before you can master the relationship between your pressing method and the function of the machine.

Step 4 knock down the curry powder on the edge of the surface of the coffee particles just pressed (horizontal drum), repeat it again, and turn 90 degrees with your wrist when pressing down. Then, clean up the coffee particles around the filter cover.

Step 5, lock the filter cover, put the water in according to the instructions of the machine, press the switch, and the steam begins to pass through the coffee powder.

Brilliant secrets:

Some household Italian coffee machines have the function of wetting coffee particles, that is, after pressing the switch for 5 seconds and 2 seconds, the coffee tree is moistened with a little moisture before it is extracted with a large amount of steam. You can tell from the panel light of the coffee machine what it is doing. If the coffee machine you bought does not provide this function, you can also use your own operation switch. Practice: after pressing the start button for 10 seconds, temporarily shut down the computer. Wait about 3 seconds. And turn it back on.

Coffee granule

The same goal can be achieved in this way:

1. After putting the coffee particles into the filter cover, if the coffee particles are relatively fine, the pressure should not be too heavy, otherwise the water is not easy to pass through, which will cause excessive extraction. On the contrary. If the coffee granules are thicker, press them more closely. Otherwise, the water will flow too fast and the coffee will have a raw and astringent taste.

two。 One more step of warming up the coffee before brewing will make the coffee more mellow.

3. The coffee should be kept warm on the coffee machine for no more than 20 minutes so as not to lose its original flavor.
