Coffee common sense the difference between American coffee and Italian coffee

espresso machine

Usually has a boiler to produce hot water, hot water pressure to about 9 atmospheres after flowing through the metal filter of coffee beans and brew coffee, this pressure hot water brewed coffee is generally thicker, and there will be emulsified fat, usually called espresso coffee or espresso. There are many kinds of Italian coffee machines. For general commercial use, the most common one is a single boiler. There are also double boilers and multiple boilers. Of course, the price also becomes expensive. In addition to the general electronic control switch, there are also pull-type Italian coffee machines. Commercial ones range from 40,000 to 500,000, and the list goes on.

American coffee maker

Usually divided into upper and lower two layers, the use of ground coffee beans in advance will be placed in the upper funnel with filter paper or metal filter container, the lower layer is glass or ceramic coffee pot, pour cold water into another separate interval. When starting, the cold water is heated to about 90 degrees Celsius and gradually introduced into the funnel-shaped container, so that the hot water flows into the coffee pot below through the coffee powder.

In addition to cooking coffee, this coffee machine can also make tea.

Italian Coffee: High Pressure Extraction

Espresso machines use high-pressure hot water to extract coffee through a coffee grinder. Because the current espresso machine uses an air pump to increase the pressure in the boiler to achieve the pressure required to extract the cream, it is also called a pump coffee machine. The older Italian coffee machine used to need to manually push the pressure lever to pressurize the boiler, also known as the La Ba coffee machine, and now the value of the La Ba coffee machine is mainly reflected in its ornamental nature, the convenience of use and the taste of coffee are not as good as the pump coffee machine.

American Coffee: Atmospheric Extraction

It is usually brewed in an American drip pot, which is similar to an espresso machine. American drip also makes hot water pass through a coffee powder tank to extract coffee. But the difference is that hot water is atmospheric.

other aspects

American coffee machine, no pressure, only black coffee, that is, American coffee. No fancy coffee.

2, Italian coffee machine, there is a certain pressure, you can use pressure to make ESPRESSO coffee with a fairly thick coffee oil. There's regular espresso, you can make lattes, you can make foam, you can make cappuccinos. And other fancy coffees.

3, price: American coffee about 200 yuan is quite good quality. Italian coffee machines, prices range from 700- 100,000.

How to buy an espresso machine

Italian coffee production and machinery have a lot to do with it. A perfect cup of Italian coffee, like a good record, can be called a combination of art (the maker's craft) and technology (the design of the coffee machine). Making a good cup of Espresso is one of the most challenging "activities" for both a coffee lover at home and an experienced Barista in a cafe. The purchase of Italian coffee machines is of course divided into two categories: family and professional. Please see our carefully prepared espresso machine selection guide.

How to buy an espresso machine

Home espresso machine

In principle, home-made espresso is "impossible." This is why mocha pots are used almost exclusively in Italian homes. Perhaps Italians have already agreed not to learn to make coffee themselves; it's too hard. So everyone went out to the street for coffee. That's what espresso is all about.

Americans are willing to spend time and effort on good coffee these days, perhaps because it's so hard to find good coffee, or because they have spare cash and time.

Italy also has a type of coffee machine, mainly for baristas at home. Commonly known as semi-professional coffee machines;prosumer machines. For example, ECM's Giotto coffee machine, although more suitable for small cafes, but due to domestic certification system restrictions, so now can not import. Or a better home coffee machine, such as Miss Silvia of Rancilio (note that Americans use this machine at home with PID thermostat; otherwise it is difficult to guarantee good coffee). These machines usually use professional handles, but the boilers are very small, and the pumps are mainly vibration pumps. However, semi-professionals often use E61 brewing head, so it is good to use. But who can afford that? It is best for baristas to use at home.

Professional espresso machine

General professional machines are good, mainly Italian. Of course, some of them are more solid, some are not very used, and they are easy to break. Especially automatic. Because of the electronic control board, this kind of product quality is not very good, it is easy to malfunction. In comparison, manual (of course, not "true" pull rod type, but "small" pull rod type) and semi-automatic are less prone to failure. The manual switch is mechanical, almost indestructible. The semi-automatic one has a large power switch, thick wires and is hard to damage. Especially if there is no local dealer to provide repair and warranty, it is best to use this type of machine.

Some people pay attention to the appearance, but don't forget, usually only good machine business is good, profit is good, so there is money to make the machine better. So appearances aren't completely meaningless. The easiest thing is to have no plastic parts.

E61 Brewing head, this is a special part. Professional machines are best served with this. Because it has two advantages, one is to use the hot water in the boiler to heat the brewing head constantly, to avoid the brewing head temperature is 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-soaking" is not easy to master, easy to forget, and may also operate improperly. Machines with this function are slightly more expensive than ordinary machines, but the price difference is not very large. Generally, it is not obvious in terms of the price of professional coffee machines.

Then there is the double pressure gauge, of course, this refers to the vibration pump. Some machines use pressure gauges that are not accurate enough, which is inconvenient for adjusting pressure.

Many people now emphasize temperature control, including David schomer. So there are some new developments with direct temperature display and temperature adjustment. However, although this type of machine is easy to use, because many parts are electronic products, it is best to find a local dealer to provide warranty and repair services. Otherwise, it may affect the operation of the cafe.

Finally, it is better to buy a new machine. Second-hand phones tend to be used for a long time, and if they haven't failed yet, they are about to fail. Therefore, it is likely that maintenance problems will often be encountered when using it. Or if you don't understand the fault of the machine, it may affect the coffee making, and you don't know it, which is even worse.
