How Does Machine Espresso Work?
Machine espresso uses precision pressure and mind-blowing filter technology to make the delicious coffee we enjoy. But how exactly does it work?
To make espresso, hot water is pushed under pressure through finely ground coffee espresso machine. The process is similar to making drip coffee, however the main difference lies in the pressure.
The Group Head
As the name implies the group head is where you put your portafilter in when making espresso. It is responsible for dispersing the water into the portafilter and controlling the pressure that results from the extraction. There are several different types of group heads, each with their distinct advantages and drawbacks. Some focus on temperature stability, others on pre-infusion options, and others are designed to control the lever. There are some that contain a variety of features, like the E61, which is the standard choice for many baristas for its ability to offer multiple perks in a single package.
As you can see in the image above, the group head has several notches to place your portafilter before twisting it by hand to secure it. There is also a gasket of rubber which is located inside the notches and helps to create an airtight seal after inserting your portafilter into the machine. The notches permit precise placement of your portafilter. This is essential for an accurate extraction.
In addition to allowing you easily connect your portafilter, the group head is responsible for maintaining a consistent temperature. This is accomplished by cycling hot water around the portafilter, and through the brew-basket, making sure that the temperature is constant to extract the coffee. This is crucial, since even a small difference in temperature can make the difference between a excellent and great espresso.
The Pump
In contrast to piston machines that are manually operated, which rely on a lever to pressurize water, rotary espresso machines rely on motorized pumps that provide the nine atmospheric bars of pressure necessary for espresso extraction. The pressure is created by pumping water through a heat exchanger and then through the ground coffee.
Pumps tend to be cheaper than piston-driven machines, and they tend to last longer, although both types of machines may get damaged through overuse and lack of cleaning. Pumps are also more complicated mechanically, which can increase the price of even the simpler models.
Some espresso machines can eliminate the pump completely and use steam pressure to brew espresso. The drawback is that the boiler that produces steam also increases the temperature of the water to boiling and can result in over-extraction. The machines must also continuously rebuild their pressure between cups. This takes energy and time.
Many best budget espresso machine machines employ an rotary or vibrating pump, which has a vibration model using a vibrating disc to generate the pressure and the rotary model pushing hot water through the grounds at high speed. Both machines can make great espresso however rotary machines tend to be quieter, more durable and less likely to break.
The Boiler
The boiler is the part that heats the water to the ideal temperature to extract. The steam created will eventually reach the portafilter, which contains the espresso coffee grounds. It is then pumped into the cup. During this process, the steam creates pressure to push through the coffee grounds. This results in a crema on top of the espresso. This is a hallmark of a great espresso.
There are three kinds of espresso makers, which differ in the type of pump they use and how hot the coffee is. There are different ways to control the amount of brew, as well as the size of cup that can be produced by the machine.
The first espresso machines were steam-types. The earliest espresso machines were steam types. This led to the coffee espresso machines tasting burnt and bitter. The modern espresso machine coffee machine was designed by the Milanese manufacturers Luigi Bezzerra & Desiderio Pavoni.
The most popular espresso maker is a semi-automatic one that has an electric pump. These are the things people think of when they think of an espresso maker. With a semi-automatic espresso machine, you need to grind the beans and then tamp them by hand, but the pump regulates the flow of water and pressure. This is an excellent compromise between human touch and mechanized consistency.
The Filter
Typically, espresso machines use a filter to separate out the coffee grounds as they pass through the hot water. The filter is also a vital component of the machine's temp control, as it helps prevent overheating.
A filter can also help with flavor, as it permits an extended flowering time. This helps the beans to release their flavors and provides an opportunity to improve extraction.
It is important to remember that even the most efficient filter could result in a poor cup of coffee. The quality of the beans, and the extraction, remain crucial.
This is where the magic happens, it's what makes an espresso really taste great. The grouphead, often referred to as the brew head, is the place where the portafilter (the thing you put the coffee grounds into) is located when you're making espresso.
In an espresso machine that is driven by steam, hot water is heated in an airtight tank to create steam. Steam then pushes the hot water through the grounds at high pressure. These kinds of machines are usually less expensive and easier to maintain than pumps-driven models. However, they are limited in their ability to create the ideal brewing conditions, since they are only operating at 1-1.5 bars of pressure. However, the perfect shot requires 9-10 bars.
In recent times, espresso machines powered by compressed air-pump are becoming increasingly popular. They use an air compressor to force the hot water through the grounds, and are far more portable than steam-driven electric machines.
