Coffee and Espresso Machines
Espresso machines utilize pressure to make water into finely ground and tamped beans. They make a rich, tasty brew.
Good Housekeeping Institute experts recommend models that brew at 9 bars minimum for a perfect extraction. Beware of manufacturers who tout greater pressure than what is necessary.
Types
The espresso machine (also known as a coffee and Espresso maker) brews coffee that is more concentrated, of higher quality, than your favorite cafe drinks. It uses an average of nine bars of pressure. These machines tend to have a variety of features like temperature and brew strength control, programmable brewing, and multiple sizes of drinks. They could also have steam wands for manual or automatic use to create texture-rich milk for latte art. There are three types of latte art: semi-automatics, super-automatics and automated. Each comes with its own level of supervision and control.
The most popular espresso machine for specialty coffee shops is semi-automatic models. This allows baristas to have full control over the brewing process, however, it's not as user-friendly as a fully automated machine. To get the best espresso shot, you need to grind the beans, fill the portafilter and tamp it down, and adjust the time of extraction.
Automatic machines have a built-in grinder, and they measure and tamp the grounds for you. They automatically disperse the proper amount of water needed to extract the espresso, and they often feature a programmable drink size function. They were the most commonly used espresso machine in our lab tests, and they provide a great combination of consistency and human control.
Functions
You'll need a reservoir hold the water that you use to make coffee, whether you opt for a steam-driven or pump-driven machine. You'll also have a heating component that is used to heat the water to create the pressure necessary to extract the coffee from the grounds.
When the button to brew is pressed to brew, the water inlet valve is closed to ensure that only hot water under intense pressure can pass through the portafilter and into the ground coffee. The water will take about 25 seconds to transform into espresso.
The insulated tubing, also known as the hot-water tube runs from the reservoir to the spout on top of your machine. The heating element that resists is responsible for heating the water as the water moves through the aluminum tube and metal warming plate.

Also, look for a knob that can activate the steam wand for frothing milk and making latte art. The front of the machine includes a pressure gauge that will provide the operating pressure of the boiler and pump. It is recommended to look for a coffee machine that has two needles to see the pressures at the lowest and highest.
If you're looking for more than only espresso, choose the machine that comes with different sizes of brew. This includes ristretto. You can also find models that have the ability to remove the milk hopper for effortless, easy frothing and the ability to easily switch between different types of milk. Make sure you choose a model with an inbuilt softener, if you have hard water to prevent the accumulation of minerals and ensure fresh espresso.
Certain manufacturers employ PID (proportional integral, integral digital) thermostat to maintain the temperature of espresso making. This feature allows for the same high-quality, consistent cup of espresso each time. This feature also reduces energy costs because the machine only runs when necessary.

Some components of the machine need to cleaned every two to three weeks, such as the water tank and the grinder.
You should also backflush the machine each week. This involves locking the portafilter in place and running the brew cycles several times.
