How Does Machine Espresso Work?
Machine espresso employs precise pressure and mind-blowing filter technology to create the perfect cup of coffee. How exactly does it work?
To make espresso hot water is forced under high pressure through finely ground coffee. The process is similar to making drip coffee, but the key difference is in the pressure.
The Head of the Group
The group head is the portafilter that you insert when brewing espresso. It is responsible for dispersing water into the portafilter and controlling the pressure of the resulting extraction. There are a variety of types of group head, each with their unique advantages and drawbacks. Some are focused on temperature stability, others on pre-infusion options, and others are designed to control the lever. Some come with a combination of both, like the E61. This is a favorite among baristas because it offers multiple benefits in one package.
As you can see in the photo above the group head is made up of numerous notches that you can place your portafilter and twist it by hand to secure it. A gasket made of rubber is placed inside the notches, which helps create a seal as you insert your portafilter. The notches on the head permit a precise location of the portafilter which is crucial to ensure an even extraction.
Apart from allowing you easily place your portafilter in, the group head is responsible for maintaining an even temperature. It does this by cycling hot water through the brew pan and around the portafilter, ensuring that it's always at the right temperature to extract. It is important to realize that even a slight differences can make the distinction between a good and a great espresso.
The Pump
The motorized pumps used in espresso machines that rotate provide the nine atmospheric bar pressure required to extract espresso. This is different from manually operated piston machines that employ levers. This pressure builds up by removing tap water from a reservoir and pumping it through a heat exchanger prior to being pumped through the ground coffee in the group head.
Pumps are typically less expensive than piston-driven models, and they tend to last longer, however both types of machines may be damaged by excessive use and inadequate cleaning. Pumps are also more complicated mechanically, which can increase the cost of even simple models.
Some espresso machines do away with the pump completely and use steam pressure to brew espresso. This can lead to over-extraction as the boiler that produces steam also heats the water until it comes to a boil. Additionally these machines typically have to rebuild their pressure between cups, which requires time and energy.
Many espresso machines make use of either a vibration or rotary pump. A vibration model employs a vibrating disk to generate pressure, while the rotating model pushes hot water through the ground at a high speed. Both types of machine can make a great Uk espresso machine, however Rotary machines are quieter and more durable than vibration pumps.
The Boiler
The boiler is what makes the water warm to the ideal temperature to extract. The resulting steam is then transferred to the portafilter containing the ground espresso machine with frother coffee and is then funneled down into the cup. During this process the steam causes enough pressure to push the coffee grounds through. This produces a layer of crema that is then poured over. This is a hallmark of a great espresso.
There are three types of espresso makers. They differ in the type of pump they employ and the degree of heat that the coffee is. There are a variety of ways that the brew can be controlled as well as the size of the cup that the machine can produce.
The first espresso machines were steam-type. They had a single boiler to make steam and brew, however the pressure they were able to produce was not very high - two bars of atmospheric pressure at most. This led to the coffee tasting bitter and burnt. The modern espresso machine was developed by the Milanese manufacturers Luigi Bezzerra & Desiderio Pavoni.
The most commonly used espresso maker is a semi-automatic machine with an electric pump. When people think of espresso machines, they picture these machines. Semi-automatic machines require you to grind and tamp your beans yourself however the pump controls the water flow and pressure. This is a great compromise between the human touch and mechanized quality.
The Filter
Espresso machines usually use filters that separate the grounds of the coffee from the hot water. The filter is also an essential part of the temperature control system, since it helps prevent the machine from overheating.
It also enhances flavor, as a filter allows for a more prolonged bloom time. This allows the beans to let their nuances out, and also allows for better 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 as well as the extraction, are still crucial.
It's in this area that the magic takes place. This is the reason why espresso tastes so delicious. The grouphead, also referred to as the brew head, is the place where the portafilter (the thingy you put the coffee ground into) sits when you're making italian espresso machine.
Steam-driven cafe espresso machine machines use hot water that is heated inside an airtight container to create steam. The steam then moves hot water through the coffee grounds under high pressure. They are less expensive and are easier for the user to maintain than pumps-driven models. They are however limited in their ability 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 times, espresso machines powered by compressed air-pump have become increasingly popular. They utilize an air compressor to force hot water through the ground. They are also more mobile than electric steam-driven espresso machines.
