The espresso machine that made the world popular is the epitome of using this ultra-fast method. This espresso machine has a short history and was invented by an Italian engineer Luigi Bezzera at the beginning of the 20th century. His logo is pictured on the left (we also bought this brand of machine). It can make coffee in tens of seconds, not to mention it is very popular in coffee shops. In the earliest model, the water was pressurized by hand, and then came the design of pressurizing water with a pump. Today, most people use water pump type, because it saves effort. Even if you see a machine with a handle in a coffee shop, it's probably just an electric switch. In the picture on the right, my partner also has one of the machines produced by la Pavoni. The water inlet was not tightened once, and the water pressure made a hole in the ceiling.

There are generally three types of espresso machines on the market:

Hand pressurizing machine

Heat the water temperature to increase the pressure. This will only be a household machine, of course, the water temperature will be too high.

2 the hot water is pressurized by hand, as in the picture on the right.

(3) the hot water is pressurized by a pump. The pump is also divided into two types, one is vibrating, the other is rotating. The pressure of the former is less uniform than that of the latter, but cheaper.

Among the household phones, Rancilio Silvia is the most famous, which is of course related to performance-to-price ratio. This kind of household coffee machine is different from commercial ones, only a single boiler, if you want to milk, you have to press another button to raise the water temperature to output steam. So if you want to make a few cups of milk coffee at the same time, you have to make a few cups of Espresso first, and then wait for the heat to milk. After the fight, it is necessary to release steam and return to the temperature suitable for making Espresso. So every penny, a penny of goods. In fact, due to the small size of the built-in boiler, the effect of continuous production of Espresso will also be reduced due to the drop in water temperature.

To make a good espresso, the most important thing for the coffee maker is to control the water temperature and pressure. We often read advertisements about 15 bar pressure, but in fact it's just a home phone. The commercial machine is generally set to 9 bar, but that is constant. If it is offset, you can open the chassis and adjust it. It is difficult for household machines to maintain pressure and temperature. 15 bar is only a top  output.

The larger the boiler is, the less effect the effluent has on the temperature. In addition, many factories also adopt the design of more boilers to avoid affecting the temperature when entering cold water. Since each cup of Espresso is only about 30 cc, the section of hot water from the boiler to the head is also very fastidious, and there will be a special design to keep the temperature around 92 degrees Celsius.

It should be fully heated before use every day, and the brewing head and filter handle should be washed with hot water in order to enjoy the first cup of coffee of the day. Remember to clean all parts after use. There is a blind filter with a large coffee opportunity, which is used to clean the water outlet, because the coffee will pour into the inner channel of the machine due to the maintenance of pressure, and it will accumulate flavor over time. There is a special powder for cleaning on sale. Details should be known from the coffee machine manufacturer.

With an Italian coffee machine, the grinding of coffee powder is relatively young, and the goal is to finish the water in 20-30 seconds. Of course, it will not taste enough if it is too fast, and it will become bitter for too long. The ground coffee powder should be swept flat on the filter handle, about 8 grams per shot, and then flattened with a filler of about 30 pounds, which is used to determine whether the grinding degree is sufficient or excessive when coming out of the water. The whole step is to determine the level of barista, because it is impossible to do the same every time without a little practice. It is best to buy a measuring cup and mark it at 30 cc, which is even clearer.

If you want to make the next cup after brewing, don't move away from the filter handle and keep it warm on the machine. This problem is a common problem in many coffee shops. Just pay attention to it. When I was making cafe, many customers asked me why I lost so many cups of coffee after using it once. You can see that the advantage of Espresso machine is that it can really quench the essence of coffee beans in a short time, and then make a second cup you will only taste bitter. But if you often stay in coffee shops, you will not be unfamiliar with this smell, because there are really some shops who think that they should not be wasted.

Finally, remember to clean, and the taste will be better!
