How Does Machine Espresso Work?
Machine espresso utilizes precise pressure and amazing filter technology to make the perfect cup of coffee. But 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 you insert when brewing espresso. It distributes water into the portafilter, and regulates the pressure of extraction. There are many different types of group heads each with their own advantages and drawbacks. Some are designed for the stability of temperature while some are designed to handle pre-infusion. Some are designed to control the lever. There are some that include a mix of features, like the E61 that is the standard choice for many baristas due to its capacity to provide multiple benefits in one package.
As you can see in the photo above, the group head is fitted with a variety of notches. You place your portafilter in these notches, then turn the head around to secure it. A gasket made of rubber is positioned inside the notches to help create a seal when you insert your portafilter. The notches on the head permit a precise placement of the portafilter, which is necessary for an even extraction.
In addition to allowing you easily place your portafilter in, the group head is also responsible to maintain an even temperature. It does this by cycling hot water through the brew pan and around the portafilter, making sure that it is always at the correct temperature to extract. It is important to remember that even a few degree difference can make the difference between a good and great espresso.
The Pump
Contrary to manual piston machines which rely on a lever that pressurize water, best espresso Machine Under 200 Rotary espresso machines rely on motorized pumps to supply the nine atmospheric bars of pressure needed for Best Espresso Machine Under 200 extraction. This pressure is generated by pumping water through a heat-exchanger and then through the ground coffee.
Pumps tend to be less expensive than piston-driven machines, and they tend to last longer. However, both types of machines may degrade with overuse and insufficient cleaning. Pumps are also more complicated mechanically, and can add to the cost of even the simple models.
Some espresso machines make use of steam pressure instead of a pump for brewing italian espresso machines. This could lead to over-extraction since the boiler that makes steam also heats the water until it comes to a boil. The machines also need to constantly rebuild their pressure in between cups. This requires energy and time.
Many espresso machines employ the rotary or vibration pump, which is a vibration model using a vibrating disc to create pressure, and the rotary model pushing hot water through the grounds under high end espresso machine speed. Both types of machines can produce an excellent espresso, but the rotary pumps are quieter, and more durable than vibration pumps.
The Boiler
The boiler is the element that heats water to the ideal temperature for extraction. The steam produced is then directed to the portafilter, which is the container that holds the espresso coffee grounds. It is then poured into the cup. The steam generates enough pressure to push the grounds of the coffee through. This creates a foam on the top of the espresso. This is the hallmark of a great barista espresso coffee machine.
There are three kinds of espresso makers, which differ in the kind of pump they use and the degree of heat that the coffee is. There are various ways to control the strength of the brew and the size of the cup that can be produced by the machine.
The first espresso machines were steam types. The earliest espresso machines were steam-type machines. This resulted in the coffee tasting burnt and bitter. This is the reason why Milanese manufacturers 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 picture these machines. With a semi-automatic espresso machine, you need to grind the beans and then tamp them by hand. The pump controls the flow of water and pressure. This is an excellent compromise between human touch and the mechanized consistency.
The Filter
Typically, espresso machines utilize filters that separate the coffee grounds as they pass through the hot water. The filter is also a crucial component of the temperature control system, since it helps prevent the machine from overheating.
Filters also aid in flavor, as it permits an extended flowering time. This allows beans to release their flavor and gives an opportunity to improve extraction.
It is important to keep in mind that even the most efficient filter can result in a bad cup of coffee. The quality of the beans and the extraction, are still very important.
It's in this area that the magic happens. This is what makes espresso taste so good. The grouphead (also known as the brewhead) is where you put the portafilter, the thingy that you use to put the grounds of your coffee into while making espresso.
Steam-driven espresso machines use hot water that is heated in an airtight container to produce steam. The steam then moves hot water through the grounds of coffee at high pressure. These kinds of machines are usually cheaper and easier to maintain than pump-driven models. They are however limited to create the perfect conditions for brewing, as they operate with 1-1.5 bar of pressure. The ideal shot requires 9-10 bars.
In recent years, compressed-air-pump-driven espresso machines have become more popular. They use an air compressor to push hot water through the ground. They are also more mobile than electric steam-driven espresso machines.
