What is Italian coffee (Espresso)

It is so far that mankind has used the most high-tech cooking method in the production of coffee, and it has reached a peak for the first time in the development of coffee brewing for the first time. It can be said that this is the wonder of chemical and physical engineering! Its appearance has not only covered people's understanding of coffee for a long time, but also pushed coffee into the category of art.

If you want to learn Italian coffee, it is necessary to understand the history and performance of the coffee machine.

The method of brewing coffee can be traced back to the Paris Trade Fair in 1855 (Paris World Expo). The purpose of the design of coffee was to shorten the working time and improve the efficiency. In order to make water pass through a certain amount of coffee powder, the inventor came up with the idea of adding water to extract coffee. However, when coffee makers used coffee machines at that time, they needed to operate various kinds of bars to control the power of the steam.

In 1945, people changed the program of the original coffee machine, and the coffee machine welcomed its first golden age after the launch of the Gaggia coffee machine. at that time, the water supply of the coffee machine was controlled by the busy door, and it was produced entirely by the strength of the coffee maker's own arms. although it was a revolutionary product, the bar coffee machine also gave coffee workers with tendinitis at the same time. In spite of this, traditional lever coffee machines are still used in some parts of southern Italy.

However, the real brew coffee came out in 1950, when Faema made a huge discovery that he replaced the spring in the lever machine with a rotary pump, which means that coffee makers don't have to use their milk to pull the lever in order to keep the water running. Now all you have to do is turn on the pump.

Today's coffee machines are already high-tech products, and they have their own advantages in the synchronization of the water cycle of cooking, to the existing controllable manual immersion system, smart tank system, PDI water system, chip data copying system, proprietary anti-steam pipe, proprietary automatic steam pipe, and so on. It is very high to see that there are always coffee machine brands that will never achieve what they have achieved now, and it is precisely because of their efforts that the progress of Italian coffee machines will never stop!

The above is an important historical process of the development of coffee machines. Simple espresso is made to pass through coffee powder with a certain amount of water (86 ~ 95 degrees) and high (8.5bar~9bar). The coffee essence extracted from China (Espresso) means "specially and quickly brewed coffee for you" in Italy.

However, the performance of Espresso has a "gold standard" respected by international standards, which will be clarified in subsequent operational training.
