How Does Machine Espresso Work?
Machine espresso makes use of precise pressure and amazing filter technology to make the coffee we love. How exactly does it work?
To make an espresso, hot water is forced under high pressure through finely ground coffee. The process is similar to making drip coffee, but the difference is in the pressure.
The Group Head
The group head is the portafilter that you place in the espresso maker when making it. It is responsible for dispersing the water into the portafilter and controlling the pressure that results from the extraction. There are many different kinds of group heads, each with their own advantages and drawbacks. Some are designed to provide the stability of temperature while some are designed to handle pre-infusion. Others are made to control the lever. Some are a combination, such as the E61. This is a favorite among baristas since it provides multiple benefits in one package.
As you can see in the photo above the head of the group is fitted with a variety of notches. You place your portafilter into these notches and twist the head to lock it. A gasket made of rubber is placed in the notches to create a seal while you insert your portafilter. The notches permit precise placement of your portafilter. This is vital for a consistent extraction.
The group head is not just able to allow you to insert your portafilter easily but also maintains the same temperature. It does this by circulating hot water through the brew basket, and around the portafilter, ensuring that it is always at the correct temperature for extraction. This is important because just a few degrees could be the difference between a excellent and great espresso.
The Pump
Motorized pumps in espresso machines rotary provide nine atmospheric bar pressure that is required to extract espresso. This is different from manually operated piston machines that employ a lever. This pressure builds up by drawing tap water from a reservoir, and pumping it through a heat exchanger before being shot through the ground coffee in the group head.
Pumps are generally less expensive than piston-driven models, and they tend to last longer, although both types of machines may become damaged due to excessive use and poor cleaning. Pumps are also more complex mechanically, which can raise the cost of even the simplest models.
Certain espresso machines eliminate the pump entirely and use steam pressure to brew espresso. The drawback of this is that the same boiler that produces steam also raises the temperature of the water until it reaches boiling and can result in over-extraction. Additionally these machines typically have to restore their pressure between cups, which requires time and energy.
Many espresso machines use a rotary or vibration pump. A vibration model makes use of an oscillating disk to create pressure, whereas the rotary model pushes hot water through the ground at a high speed. Both machines can produce excellent espresso, but rotary machines are more quiet, durable and less likely to fail.
The Boiler
The boiler is the component that heats water to the ideal temperature for extraction. The resultant steam then reaches the portafilter containing the ground espresso coffee and is then pumped into the cup. During this process, steam causes pressure to push through the coffee grounds. This creates a crema on top of the espresso. This is one of the hallmarks of a good 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 a variety of ways to control the amount of brew, as well as the size of cup that can be made by the machine.
The first espresso machines were steam type. The first espresso machines were steam-type machines. This resulted in the coffee tasting bitter and burnt. This is why Milanese producers Luigi Bezzerra and Desiderio Pavoni invented the modern espresso machine.
The most common espresso maker is a semi-automatic one that has an electric pump. When people think of espresso machines, they imagine 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 an excellent compromise between human control and mechanised accuracy.
The Filter
Espresso machines typically use a filter that separates the coffee grounds from the hot water. The filter is also a vital part of the temperature control system, as it keeps the machine from overheating.
A filter can also help with flavor, as it permits a longer flowering period. This lets the beans let their nuances out, and also allows for better extraction.
It is important to remember that even the finest filter could result in a poor cup of coffee. The quality of the beans, and the extraction process are still crucial.
It's here 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, which is the thingy used to place the coffee grounds into, when making espresso.
Steam-driven espresso machines use hot water that is heated inside an airtight container to make steam. The steam then pushes hot water into the grounds of coffee at high pressure. These kinds of machines are generally less expensive and simpler to maintain than pumps-driven models. However, they are not as efficient in their capacity to create the ideal conditions for brewing since they operate at 1-1.5 bars of pressure, while the perfect shot requires 9-10 bar.
In recent times, espresso machines powered by compressed air-pump have become increasingly popular. They use an air compressor to force the hot water through the grounds and are more portable than electric steam-driven machines.
