Beans-fresh coffee beans with certain quality

The reason why we do not talk about fresh coffee beans is to correct a misunderstanding for brown friends that fresh roasting is not directly related to quality. Freshness is a factor and a premise, but freshness is not good. For example, fresh garbage and fresh poop have nothing to do with quality. So if it is poor quality raw beans and poor baking, no matter how fresh it is.

The quality of coffee beans is the most source and soul in the process of making coffee. Without good quality coffee beans, you can't make good coffee even if you have miraculous technology.

Machine-- stable cooking pressure

Italian coffee machine uses pump to generate pressure, which is roughly divided into shock type and rotary type. Vibrating type is compact in size and low in cost. For example, a coffee machine with pump pressure 15bar or pump pressure 19bar means that the peak pump pressure can reach 15bar or 19bar, but it is not stable at a certain value, but fluctuates between 1--15bar. The lower the controllability in brewing, the worse the taste stability. Therefore, the vibrating pump is easy to produce miscellaneous and spicy taste, while the rotary pump is more balanced and leads to more sweet flavor.

The rotary pump is mainly used in commercial machines and high-end professional household machines because of its large size. The pressure can be stabilized within a fixed value, from a straight point of view, the pressure curve of the vibrating pump is fluctuating, while the pressure curve of the rotary pump tends to be a straight line, the two are not the same. The use of rotary pump is a major element of stable extraction. In addition, the noise of rotary pump is much lower than that of vibrating pump, and some vibrating pump noise makes people feel unsafe and cheap, and noise can also affect people's mood, so it is not recommended to use vibrating pump coffee machine as a business machine.

At present, the standard of esp brewing theory is 9 ±1 and 9 ±0.5,9 ±2 respectively. Here in order to facilitate the memory and understanding of the individual is set at 9.
