How Does Machine Espresso Work?
Machine espresso uses precision pressure and amazing filter technology to make the perfect cup of coffee. How exactly does it work?
To make espresso hot water is pushed under pressure through finely ground coffee. The process is similar to that of making drip coffee. However, it is the pressure that makes the main difference.
The Group Head
The group head is the portafilter that you insert when brewing espresso machine with frother. It is responsible for dispersing water into the portafilter and controlling the pressure that results from the extraction. There are numerous kinds of group heads each with distinct advantages and disadvantages. Some are designed to provide the stability of temperature while some are designed to handle pre-infusion. Others are built to control the lever. There are even some that contain a variety of features, such as the E61, which is considered to be the most popular among baristas for its ability to provide multiple benefits in one package.
As you can see in the image above The group head features several notches where you place your portafilter before twisting it manually to secure it. There is also a gasket made from rubber which is located inside the notches and helps create a seal when you insert your portafilter into the machine. The notches on the head permit a precise location of the portafilter which is necessary for an even extraction.
The group head not only lets you to put in your portafilter easily, but it also maintains the same temperature. This is done by cycling hot water around the portafilter, and through the brew-basket, ensuring that the temperature is always at the right level for extraction. It is important to note that even a few degree variation can mean the difference between a decent and a great espresso.
The Pump
The motorized pumps used in rotary espresso machines provide the nine atmospheric bar pressure needed for espresso extraction. This is different from manual piston machines that rely on levers. The pressure is built by pumping water through a heat-exchanger and then through the ground coffee.
Pumps tend to be cheaper than piston-driven machines and tend to last longer, although both types of machines can be damaged by excessive use and inadequate cleaning. They also increase the complexity of mechanical systems, which can result in costly prices for even the simplest models.
Certain espresso machine with milk frother machines can eliminate the pump completely and instead make use of steam pressure to make espresso. This can cause over-extraction because the boiler that makes steam also warms the water to boil. These machines also have to continuously rebuild their pressure between cups. This takes energy and time.
A large majority of espresso machines employ an rotary or a vibration pump. A vibration model utilizes an oscillating disk to create pressure, while a rotating model pushes hot water through the ground at a fast speed. Both types of machine can make a great espresso, however Rotary machines are quieter and more durable than vibration pumps.
The Boiler
The boiler is the one that makes the water warm to the right temperature to extract. The resultant steam then reaches the portafilter that contains ground espresso beans and gets funnelled down into the cup. During this process the steam generates enough pressure to push the grounds of the coffee through. This produces a layer of crema that is then poured over. This is a hallmark of a great espresso coffee machines.
There are three types of espresso makers, and they differ in the type of pump they use and how hot the coffee is. There are a variety of ways that the brew can be controlled, as well as the size of the cup the machine can make.
The first espresso machines were steam-based. They employed a single boiler to make both steam and brew but the pressure they could produce was not very high - two bars of atmospheric pressure at the most. The coffee tasted bitter and burned. This is the reason Milanese producers Luigi Bezzerra and Desiderio Pavoni developed the modern espresso machine.
The most common espresso machine is a semiautomatic one with an electric pump. When people think of espresso machines, they think of these machines. With a semi-automatic machine, you have to grind the beans and then tamp them yourself but the pump provides regulated water flow and pressure. This is an excellent compromise between human touch and the mechanized consistency.
The Filter
Typically, Mini Espresso Maker machines use filters that separate the grounds of the coffee as they go through the hot water. The filter is also an essential component of the temperature control system, because it stops the machine from overheating.
It also improves flavor as a filter allows for a more prolonged bloom time. This allows the beans to release their flavors, and allows for better extraction.
It is important to keep in mind that even the finest filter can make a bad cup of coffee. The quality of the beans and the extraction process remain vital.
It's here that the magic takes place. This is what makes espresso machines uk taste so good. The grouphead (also called the brewhead) is where you put the portafilter, which is the thingy which you put the coffee grounds into, while making pro espresso machine.
Steam-driven espresso machines make use of hot water that is heated inside an airtight container to create steam. The steam then pushes hot water into the grounds of coffee under high pressure. These machines are less expensive and are easier for the user to maintain than pumps-driven models. They are however limited to create the ideal conditions for brewing, as they operate with 1-1.5 bar of pressure. The perfect shot requires 9-10 bars.
In recent years, compressed-air-pump-driven espresso machines have become more popular. They utilize an air compressor to force hot water through grounds and are significantly more portable than steam-driven electric machines.
