Popular Science Analysis of the difference between Italian Coffee and American Coffee the difference between Italian coffee machine and American coffee machine

Espresso

Espresso

Italian coffee maker

It is usually equipped with a boiler to produce hot water, which is pressurized to about 9 atmospheric pressure and then flows through the powdered coffee beans in a metal filter to brew coffee. The coffee brewed by this pressurized hot water is thicker than usual and has emulsified fat. It is often called espresso or espresso. There are many kinds of Italian coffee machine. For general commercial use, the most common one is single boiler, and then there are double boilers and multiple boilers. Of course, the price also becomes more expensive, in addition to the general electronic control switch, there is also a pull-out Italian coffee machine, each has its own advantages. Commercial ones range from 40, 50, 000 to 40, 500000, and there are numerous types.

Espresso: high pressure extraction

The espresso machine uses high-pressure hot water to extract coffee through the coffee powder trough. Because today's Italian coffee machines use air pumps to increase the pressure in the boiler to achieve the pressure needed to extract cream, it is also called pump coffee machine. In the past, the older Italian coffee machine needed to manually push the pressure bar to boost the boiler, also known as Laha coffee machine, now the value of Laha coffee machine is mainly reflected in its viewing, the convenience of use and the taste of coffee are not as good as pump coffee machine.

Americano

Cafe Americano

American coffee machine

Usually divided into upper and lower layers, the pre-ground powdered coffee beans are placed in an upper funnel-shaped container equipped with filter paper or metal filters, and the lower layer is a coffee pot made of glass or ceramic, pouring cold water into another separate interval. When starting, heat the cold water to about 90 degrees Celsius and gradually introduce it into the funnel-shaped container, so that the hot water passes through the coffee powder and flows into the coffee pot below.

In addition, the coffee machine can not only cook coffee, but also make tea.

American Coffee: atmospheric pressure extraction

Generally through the American drip filter to cook, a little similar to the Italian coffee machine, the American drip filter is also to make hot water through the coffee powder tank to extract coffee. But the difference is that the hot water is at atmospheric pressure.

Other aspects

1. American coffee machine, no pressure, only black coffee, that is, American coffee. You can't make any other fancy coffee.

2, Italian coffee machine, there is a certain pressure, you can use the pressure to make ESPRESSO coffee with quite thick coffee oil. Some plain espresso can be served with milk, latte, foam, and cappuccino. And other fancy coffee.

3. Price: American coffee is of pretty good quality at about 200 yuan. Italian coffee machine, the price ranges from 7 million to more than 100 thousand.

Ps: American coffee was born after World War II. American soldiers came to southern Europe. They couldn't drink espresso, so they diluted it with lukewarm water. Because only this concentration is acceptable to them, they are named American Coffee. So! You can make the right cup of American coffee with an American coffee maker, but! Does not mean that the espresso machine is not American coffee, because American coffee has become a coffee drink, so the Italian coffee machine can also make a correct cup of American coffee!

Ps: in fact, the beans needed for espresso are different from those for American coffee. Espresso requires beans with fine grind and deep roasting, so the coffee pressed will be mellow and fragrant, so it is better to choose beans made commercially or with Italian style. On the other hand, American coffee uses an American trickling filter, which is extracted with hot water, which can better highlight the original flavor and aroma of coffee beans, and the grinding degree is thicker than that of Italian coffee. At this time, we can choose some high-quality coffee beans from a single production area, in order to better feel the different regional amorous feelings!
