15 Terms Everybody Working In The Espresso Machine Industry Should Know
Important Parts of an Espresso Machine
A good espresso machine should provide a robust and rich-bodied shot of coffee with a full flavor and intense aroma. This requires a high pressure and temperature.

Water reservoir
The water reservoir is the container that stores the cold, filtered water that is supplied to the espresso machine. It is usually removable and has lids that keep the water clean and free of dust. It is a crucial component of the espresso machine and must be kept clean to avoid clogging. Pour vinegar into the reservoir to wash it. Allow it to run for a few minutes.
The espresso machine utilizes water to pressurize the coffee grounds to extract flavors, oils and caffeine. It also creates the foam called crema. The first espresso machines were created by Achille Gaggia, who used pistons tethered to levers in order to create high-pressure coffee. Gaggia's spring pistons pushed water through the coffee into the cup. This created a brand new jargon "coffee crème" (crema).
The pump is an electric device that allows the water to flow through the heating element to warm it to the ideal brewing temperature of 195 degrees Fahrenheit. It is typically located at the bottom of the machine and is connected to a tube that runs up through the heating element. The tube is connected to hot-water and cold-water tubes. It also connects to the resistive heating elements, which are covered with white grease to keep the plate warm.
Pump
The pump is what makes an espresso machines work with, and there are various kinds. For instance certain machines use vibratory pumps, also known as vibe pumps which is an electromagnetic machine that moves back and forth within a coil to create 60 pushes per second. The pump then pushes water through the portafilter and out of the spouts. Other pumps utilize thermoblocks or thermocoils as a heating system that is able to precisely heat the water to the temperature that is desired for brewing. These systems also allow for control of pressure as well as water temperature, which is crucial to ensure a good extraction.
Pump-driven espresso machines may be equipped with a spring, piston design or an electric pump, however they all require water to flow through the coffee grounds at high pressure. The higher the pressure the better the extraction. The pump ensures that the coffee is evenly distributed and helps produce a great crema.
Other kinds of espresso machines are steam-driven or piston-driven. Steam pressure is used to push water through the grounds of the coffee in a steam-driven espresso machine. This kind of machine is less expensive however it does not provide the same amount of pressure required for extraction. There are also pump-driven espresso machines which are lighter and smaller in size, but do not require a boiler. They can be powered by a hand pump or a canister filled with compressed air (such as N2 or CO2). The espresso makers that are driven by air have lower pressure than pump-driven espresso machines but may be more convenient for some.
Steam tool
The steam wand is a thin metal pipe that is inserted from the espresso machine and releases steam hot and pressurized into your milk, resulting in foamy drinks such as cappuccinos and lattes. The steam wand can also be used to heat cocoa, tea or other hot drinks. The wand has several holes that you can turn on and off to control the amount of steam released. Some machines come with the traditional wand while others come with a Pannarello that is simpler to use, but doesn't make foam suitable for latte arts.
If you are having trouble with the frothing of your milk, it might be having a problem with the anti-vacuum valve in your espresso machine. The valve was designed in order to prevent air from being absorbed by the steam wand while it is operating. You can test it by lowering the steam wand while listening for a sound that makes a hiss. If you hear a hissing sound, this means air is being drawn into. You should raise the wand to make sure it is submerged.
You can also test the anti-vacuum by removing the wand and washing it with warm water using a soft bristled sponge or brush. Cleaning the wand is essential to avoid clogs that can hinder the foaming. If you are unable to resolve the issue on your own, then you can always consult a professional technician or the manufacturer for assistance.
Control panel
The control panel permits users to modify and configure settings. These include coffee strength as well as milk volume. These settings can be altered at any time. The display also indicates the time when the machine has to be descaled and shows whether the water tank is full.
The majority of espresso machines have hot water dispensers. This is usually found in between or next to the groups. It can be used to make hot cups or tea, if necessary. It is also ideal for cleaning and washing. Many models come with pressure gauges that indicate the current boiler pressure.
There is also a brew switch, that controls the brew cycle and the amount of shots. This is important, as the size of the espresso shot is determined by how long the grounds are in direct contact with the water. The switch can be used to also start the steaming process should you wish.
The control system on this espresso machine feels a bit old-fashioned, yet it is user-friendly. It has a narrow LCD screen that looks more like an LED. It is easy to navigate through the menus. However, there is a slight learning curve for those new to the use of espresso machines. The machine's temperature stability is impressive as well. The machine keeps a perfect water temperature between 194deg and 208deg F during the entire brewing process. This ensures a perfect extraction of aroma and ensures the same high-quality cup every time.
