Introduction of Brand recommendation for Grinding scale of Italian Coffee Machine
Italian coffee machine grinding scale requirements Brand recommendations
The influence of temperature values in Italian coffee machines is mainly the size of boilers or heating blocks, as well as good heat conduction materials, toy machines and professional Italian coffee machines have obvious differences here. Most toy machines are equipped with small boilers (below 200ml) or small heating blocks, which is difficult to achieve stable temperatures, and the temperature fluctuates greatly during the coffee extraction process. Many small household appliance brands are like this (such as Cankun, Delong, Electrolux, etc.), these brands are not professional coffee machines after all. There is also a good heat conduction material to consider, a good machine line pipe design is better, the use of copper or stainless steel as the main material of the coffee machine, they have good thermal conductivity (to ensure uniform temperature stability), otherwise from the boiler out or 90 degrees, to the coffee machine water becomes seventy or eighty degrees, in the low temperature environment will be more obvious
Sometimes people who come across a half-bottle of water say that this is an old saying, and that the best semi-automatic coffee machines are variable pressure ones.
Indeed, since 2004, the real variable pressure coffee machine has been born, gradually spreading all over the world, and has begun to enter the country in recent years.
However, the variable pressure coffee machine is not a random change, it is far greater than the pressure control requirements of the traditional semi-automatic espresso machine, plus the price of hundreds of thousands is not the average family to play.
To quote a coffee big god bird brother's explanation: "how to understand the transformation technology: at any time to reach the set specified pressure value, and can maintain stability, again change to the specified pressure value can remain unchanged, is the real transformation."
Since the local coffee machine we can not afford to play, it is still to return to the traditional espresso machine, return to the golden rule of espresso that has been circulating for half a century "under 9bar pressure, 90-92 degrees water temperature, 25-30 seconds to extract 1 ounce (30ml) of espresso" single serving.
Although this golden rule has been controversial in professional coffee forums in recent years, the 9bar pressure is basically not controversial, so a bunch of boasting 15bar or even higher coffee machines on a treasure actually refers to the highest pressure of coffee machines, which is of little significance in itself, and is generally used to fool newcomers. Stable pressure and stable temperature are the standards for measuring espresso machines.
Now that you understand the two most important factors of espresso, you can choose an espresso machine, and all traditional espresso machines are designed around these two factors.

Arabica Coffee Bean Flavor description characteristics production area treatment Variety introduction Arabica is deeply loved by Chinese people with a short history of coffee contact because of its strong fruity aroma. It was introduced to China by missionaries in the 19th century. It is widely planted in the dry-hot valley of the Jinsha River, which is more than 1000 meters above sea level in Panzhihua, Sichuan and western Yunnan. The temperature difference between day and night in this area is long, and the local people pick it.

Thirty milliliters of Italian concentrated caffeine-how many milliliters of concentrated Italian caffeine will not cause dehydration. According to the U.S. Food and Drug Administration, 98% of caffeine is consumed through beverages, so caffeine is replenished at the same time. So although caffeine is a diuretic, it doesn't really cause dehydration. However, you should drink coffee in moderation. Drinking water is.
