Extraction time of Italian Coffee Italian blend of coffee beans espresso taste balance taste thick

Usually, if your machine is idle for a period of time, when the water button is turned on, hot water and gushing steam will flow out from the head of the coffee machine at the same time, and you can also hear the sound of steam. The water temperature must be too high. For most household machines, the volume of the boiler is between 1.5 and 3 liters, so after you release some of the water, the pump will replenish the water, the boiler will start heating again, and the heating lamp will turn on, and then you can stop releasing water and wait for the boiler heating lamp to go out. At this time, the water temperature is about 90 degrees.

Extracted coffee

After releasing the water, you can put the coffee handle on the brewing head and begin to extract the coffee. What you need to remind you here is that you should press the extraction button from the handle to the cooking head, instead of putting the handle on the cooking head and getting the cup. Because the brewing heads of most coffee machines are made of copper and are very hot under the action of hot water, if you put the handle on the brewing head, all parts of the handle will soon be scalded under the action of heat transfer, scalding the coffee powder. to get a cup of espresso with a scorched flavor.

You may ask me, when I load it with immediate extraction, I don't even have time to get the cup. Very simply, you may not have noticed that after you started the extraction, the coffee did not flow out immediately. In the normal extraction state, the coffee began to flow 7-9 seconds after you pressed the extraction button. 7 seconds is enough time for you to put the coffee cup under the handle. If you press the button, the coffee will flow out. This cup of coffee is either too light or too sour. It is definitely not a satisfactory cup of coffee. If you haven't set the cup yet, don't set it up, so you don't have to wash the cup.

As we said earlier, the extraction time of espresso should be about 20 seconds. This more than 20 seconds does not start from the moment you press the extraction button, but from the moment you press the extraction button. During these 20 seconds, the amount of coffee flowing out should be about 20 milliliters.
