The difference between American coffee and Italian coffee

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.

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.

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.

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.

How to choose and buy Italian coffee machine

The production of Italian coffee has a lot to do with the machine, and a perfect espresso can be called a combination of art (the craftsmanship of the maker) and technology (the design of the coffee machine) like a well-recorded record. Making a good Espresso (espresso espresso) is one of the most challenging "activities" for both coffee lovers at home and a veteran Barista in a cafe. Of course, the selection and purchase of Italian coffee machine should be divided into two categories: family and professional. Please take a look at the espresso machine selection guide carefully prepared by the editor for you.

How to choose and buy Italian coffee machine

Household Italian coffee maker

In principle, it is "impossible" for families to make espresso. That's why mocha pots are almost always used in Italian families. Maybe Italians have reached a consensus that they don't learn to make coffee themselves, because it's too difficult. So everyone went to the street for coffee. This is the commercial significance of espresso.

Nowadays, Americans may be willing to spend money and money on it because it is too difficult to find good coffee, or because they have spare money and time.

There is also a type of coffee maker in Italy, which is mainly used by baristas at home. Commonly known as semi-professional coffee machine; prosumer machines. For example, ECM's Giotto coffee machine, although this is more suitable for small coffee shops, but due to domestic certification system restrictions, so now can not be imported. Or a better home coffee machine, such as Miss Silvia of Rancilio (note that Americans use this machine at home with a PID thermostat; otherwise it is difficult to guarantee a good coffee). Such machines usually use professional handles, but the boilers are very small and the pumps are mainly vibrating pumps. But semi-professional E61 bubble head is often used, so it is good to use. But who can afford that kung fu? Mainly baristas are best used at home.

Professional Italian coffee maker

Generally speaking, professional machines are good, mainly made in Italy. Of course, some of them are leather and solid, while others are not very useful and easy to break. Especially automatic ones. Because of the electronic control board, the quality of this kind of products is not very good and it is easy to break down. In comparison, manual (of course, not "real" lever type, but "small" lever type) and semi-automatic ones are less prone to failure. The manual one is a mechanical switch, which can hardly be broken. The semi-automatic power switch is very large, the wire is very thick, and it is difficult to damage. Especially if there is no local dealer to provide maintenance and warranty, it is best to use this kind of machine.

Some people attach importance to the appearance, but don't forget that usually only the good machine business is good and the profit is good, so you have the money to make the machine look better. So appearance is not entirely meaningless. The simplest thing is not to have plastic parts.

E61 bubble head, this is a special part. This is the best way to use professional machines. Because it has two advantages, one is to use the hot water in the boiler to constantly heat the bubble head to avoid the temperature of the bubble head being too low. The most important thing is that this brewing head has an automatic "pre-soaking" function, which is very convenient for production. Otherwise, manual "pre-immersion" is not easy to grasp, easy to forget, and may be operated improperly. Machines with this function are slightly more expensive than ordinary machines, but the price difference is not very large. Generally speaking, the price of a professional coffee machine is not obvious.

Then there is the double pressure gauge, which, of course, refers to the vibrating pump. The pressure gauges used by some machines are not accurate enough, which is not convenient to adjust the pressure.

Now many people emphasize the control of temperature, including David schomer. So there are some newly developed coffee machines with direct temperature display and temperature adjustment functions. But although this kind of machine is easy to use, because many parts are electronic products, it is best to find a local dealer to provide warranty and maintenance services. Otherwise, the operation of the coffee shop may be affected.

Last but not least, you'd better buy a new machine. Second mobile phones are often used for a long time, if there is no fault, it is time to break down. So it is likely to encounter maintenance problems when using it. Or if you do not understand the fault of the machine, it may affect the production of coffee, without knowing it, which is even worse.
