The know-how of brewing high-quality coffee with foolproof coffee technology

If you want to make a good cup of espresso coffee, in addition to having a good coffee machine, you must have the basic knowledge of operating the machine in order to make a good cup of espresso coffee.

If we want to use computers to help us work more efficiently and accurately, we must not only have a fast and powerful computer hardware, but also be equipped with appropriate software programs so that we can use them freely and save time and effort. Similarly, if you want to make a good cup of espresso coffee, in addition to having a good coffee machine, you must have the basic knowledge of operating the machine in order to really make a good cup of espresso coffee. I often drink coffee in cafes with modern decoration, and I can see the latest, large, shiny espresso coffee machine standing in the bar, but when I drink the coffee with that new coffee machine, I often feel bad taste, wrong taste or lack of aroma. The reason is that the operator has no hardware, but the software is just not enough. My friends and cafe owners who study coffee from me often ask me how to make an ideal cup of espresso coffee. Let's see what we need to pay attention to.

Note:

1. Use freshly roasted or well-packaged coffee beans, buy whole beans, and grind the coffee only when making it.

two。 Pay attention to the thickness of ground beans. The ground powder of espresso coffee must be finer than fine granulated sugar.

3. Use the correct amount of powder to brew coffee, usually the ideal amount of coffee powder for a cup of espresso coffee is 7 grams.

4. Put the coffee powder into the handle and use a flattener to rotate and press the coffee powder to make it smooth and uniform. This step is very important, if the pressure is too light, the coffee powder is distributed unevenly and loosely, and the water flows through too fast, which will lead to insufficient or uneven coffee extraction.

5. The best water temperature for making ideal espresso coffee is 90.5 degrees Celsius.

6. The pressure of the water in the coffee machine must have 130PSI, that is, the pressure of 9 atmospheric pressure, in order to effectively and quickly extract the best taste of coffee.
