Tips for making a good Espresso
To make a good espresso coffee, in addition to having a good coffee machine, the basic knowledge of operating the machine must be possessed in order to really make a good espresso coffee.
If we want to use computers to help us work more effectively and reliably, we must first have a computer hardware with high speed and strong functions, and we must also cooperate with appropriate software programs to use them freely and save time and effort. Similarly, to make a good cup of espresso coffee, in addition to having a good coffee machine, the basic knowledge of operating the machine must be possessed in order to really make a good cup of espresso coffee. I often drink coffee in modern coffee shops. At first glance, I can see the latest, large, shiny espresso machine standing in the bar. However, the coffee made by the new coffee machine often tastes bad, tastes wrong or lacks aroma. The reason is that the operator has no hardware, but the software is not enough. My coffee school friends and cafe owners often ask me how to make the perfect espresso. Let's see what needs attention first.
Notes:
1. Use freshly roasted or well-packaged coffee beans, buy whole beans and grind them when making coffee.
2. Pay attention to the size of the ground beans, espresso coffee must be ground more finely than fine sugar to be appropriate.
3. Brew coffee with the right amount of powder, usually the ideal amount of coffee powder for a cup of espresso is 7 grams.
4. Put the coffee powder into the handle, and rotate the coffee powder with a flattening device to make it smooth and uniform. This step is very important, if pressed too lightly, coffee powder will not be evenly distributed and loose, water flow through too fast, will lead to insufficient or uneven coffee extraction.
5. The best water temperature to make the ideal espresso is 90.5 degrees Celsius.
6. The pressure of the water in the coffee machine must be 130PSI, which is equivalent to 9 atmospheres of pressure, in order to effectively and quickly extract the best taste of coffee.

Recently, I heard a saying: coffee is roasted, but during the bean-growing period, there is a strong sense of smoke. What I want to say is that the sense of smoke can not be lost by raising beans. There are two situations in which the sense of smoke can be produced. First, the flavor of coffee itself is mainly smoky, and there is a lot of smoke in the flavor of this bean. Second, it is caused by defects in baking, that is, it is difficult to make exhaust and firepower.
