There are so many ways to brew espresso, why did you choose to study espresso? Okay, what are the extraction criteria?

The common painful experience of all coffee beginners is that they do not know the objective criteria of coffee, including the flavor of beans, how fine they should be ground, how to cook them, and how long it takes to cook them. The Italian coffee machine provides a very precise standard, the traditional definition, the use of 9 atmospheric pressure, extraction time 25 seconds, brewing 30cc coffee, through the above standards, we can go back to determine the amount of beans, grind thickness and fill the pressure channel to achieve a standard extraction.

As the brewing of the Italian coffee machine will magnify and highlight the characteristics of the coffee flavor, through the standardized brewing of the Italian coffee machine to find out the original flavor of the coffee (although it will be relatively strong), which can be used as a reference for the adjustment of the flavor and methods of other brewing methods. This is the inspiration given to me by the Italian coffee machine. In addition, in addition to the number of seconds, espresso can be used to determine whether the extraction is complete or not, and the cup can be opened immediately when the color of the outflow becomes lighter, which is also one of the advantages.

What is the secret of brewing coffee beans and espresso?

The brewing method of Italian coffee needs to think about the complementarity of "baking depth of beans" and "collocation of water temperature", "thickness of grinding" and "brewing time", so general lovers choose the depth of bean baking in their favorite way of brewing. To put it simply, shallow culture is suitable for higher water temperature to balance sour taste, while deep cultivation requires lower water temperature to suppress bitterness. If soak for a long time, such as "French pressure", take a thicker grinding, the focus is to understand the principle of cooking to think.

I usually use an American coffee machine with a blade electric bean grinder as my alarm clock. Set the time, and the sound of the bean grinder will wake me up every morning. When the aroma of the coffee floats out, you will know it's time to get up. You may say that the grinding of this bean chopper is uneven, so I think from the point of view of uneven grinding, increasing the weight of beans to adjust the state of cooking, plus the beans are fresh enough, there will still be good coffee waiting for you to get up.
