How to Properly Maintain and Clean an Espresso Coffee Machine
Espresso machines push water through the coffee grounds with pressure. This type of brewing produces more strength than drip coffee. The machines require 9 bars of pressure to extract flavor from the coffee grounds.
There are three kinds of espresso machines. They include manual, semiautomatic and fully automated. Semiautomatic machines permit you to regulate grinding, tamping and extraction time. They provide a balanced balance between the human hand and mechanised control.
Simple to use
The best espresso machines are easy to use. They feature an adjustable thermostat that helps keep water at the ideal temperature and a pressure-pump that raises the amount of water per shot. The increased pressure makes the grounds to dissolve more quickly and produces a crema with the perfect consistency. These machines also have a milk mixer to make espresso-based drinks, such as lattes and cappuccinos.
The traditional steam-driven electric machines use an airtight tank to heat water until it reaches boiling, then release the pressure to create a shot of espresso. While they're affordable and compact however, they only have 1-2 bars of pressure, which is less than the recommended 9 bars required for espresso.
Semi-automatic espresso machines work by infusing hot water into an already-ground, pre-tamped portafilter of beans. The barista handles the extraction process, but must manually grind, measure and then tamp down the beans prior to each cup. While this model is more expensive than other models however, it gives more control and stability, says Jai of Blank Street Cafe.
Full-automatic espresso machines are simpler to use than semiautomatic machines because they do not require barista's role in the brewing process. Most have built-in grinders that connect to the portafilter. They then automatically grind and dosing the beans and can be altered to create various drinks. Some even have a milk hopper which can create froths and pours milk for you.
Easy to clean
Espresso machines produce a more dense, more full-bodied shot by making use of higher temperatures and pressure than drip coffee makers. They also include an automatic milk frothing device, that allows you to make lattes and cappuccinos. In this way, they require more regular maintenance than a drip machine, including descaleing and routine cleaning. Fortunately most espresso machines are simple to clean. Several models on our list have been made to make cleaning easier.
Most espresso machines come with a portafilter, which holds the grounds of coffee during brewing. Some models also have a group head that is a set of components that actually extract the coffee. Backflushing your machine on a regular basis will keep these parts clean and free of grit and gunk. This involves rinsing and brushing the group head, and then locking the portafilter and running the brew cycle multiple times. Many coffeehouses backflush their equipment daily, but home users should only have to do it once a week.
It is recommended to use softened or filtered water, as it can reduce the accumulation of mineral and the need to descale. However, it is important to note that a reasonable amount of minerals is essential for proper extraction. Too much mineral will muddle the taste. Too little could result in weak, salty coffee. Maintaining your machine will ensure that it continues to function well and taste fantastic for as long as you have it.
Easy to maintain
An espresso machine is a magnificent piece of equipment that allows you to serve a broad variety of coffee drinks. A carafe-style coffee maker can provide the same results however an espresso machine requires an increased pressure and temperature. To achieve this, the machine should be cleaned and maintained properly. Thankfully, you don't have to be an expert to keep your espresso machine running smoothly.

It's also important to wash the drip tray on a regular basis because it is the place where you collect the coffee waste that is generated from each brewing cycle. This can become a breeding ground for mold and bacteria, which can alter the taste of your coffee. In addition, you should clean the exterior of your machine often to prevent milk and coffee residue from building up.
