How to Properly Maintain and Clean an Espresso Coffee Machine
Espresso machines make use of pressure to push water through coffee grounds. This type of brewing results in more strength than drip coffee. The machines require nine bars of pressure to extract the flavor from the ground.
Espresso machines are available in three main types. There are espresso machines for home of espresso machines: semiautomatic, manual and fully automatic. Semiautomatic machines allow you to regulate the grinding, tamping, and extraction time. They are a good balance between human control and mechanised accuracy.
Easy to use
The top espresso machines come with an intuitive interface. They have an adjustable thermostat that maintains water at the right temperature and a pressure pump that increases the amount of water per shot. The higher pressure allows grounds to dissolve more quickly and produces a crema with the perfect consistency. They also have a milk frother to make espresso-based drinks such as lattes and cappuccinos.
Traditional steam-driven espresso machines make use of an air-tight tank to heat the water until it reaches a boiling point, and then release the pressure into a shot of coffee. They are small and cost-effective however, they only provide 1-2 bar of pressure. This is less than the ideal 9 bar required for espresso.
Semi-automatic espresso machines dispense hot water into a filtration system that is filled with beans that are pre-ground and pretamped. The barista is responsible for the extraction process but has to manually measure the amount of beans, grind and tamp each cup of beans. Although this type of machine is more expensive than other machines however, it gives more control and stability, says Jai of Blank Street Cafe.
Full-automatic espresso machines take out the barista from the preparation process, making them more user-friendly than semi-automatic models. Many come with built-in grinders that plug into the portafilter. They automatically grind and dosing the beans and can be altered to create various drinks. Some even come with a milk hopper that can froth and pour milk for you.
Easy to clean
Espresso machines make use of higher pressure and heat than drip coffee makers to create an extremely full-bodied and thick shot. They also have a milk frothing mechanism, which allows you to make cappuccinos and lattes. This means that they require more regular maintenance than a drip machine that includes descalers and routine cleaning. Fortunately that most espresso machines are very easy to clean. A number of models on our list were designed to make cleaning simpler.
Most espresso machines have a portafilter to hold the coffee grounds during brewing. Certain models also have a group head that is a set that actually extract the coffee. To keep these components free of grit and gunk it is necessary to backflush your machine on a regular basis. This means cleaning and brushing the portafilter, locking it and running the brew cycle a number of times. Backflushing is routinely done in a lot of coffeehouses, however at home, it should only be done once every week.
It is recommended to use filtered or softened water, as it reduces the accumulation of minerals and the requirement to descale. However it is important to remember that a moderate amount of minerals is essential for proper extraction. Too much mineral will muddle the flavor. Too little could result in a weak, salty coffee. Maintaining your machine will ensure it remains in good working order and taste great for as long as you own.
Easy to maintain
A coffee machine permits you to make various coffee drinks. But, unlike the typical carafe, an espresso machine requires a higher degree of pressure and temperature in order to get the desired results. To achieve this, it should be maintained and cleaned properly. You don't need to be skilled to keep your espresso maker running smoothly.
You'll need to clean the gasket every week. This is where coffee oils collect and can create bitter taste from the espresso that has gone rancid. Backflush your group using water-espresso machine cleaner. It is also recommended to scrub the screen of your group including the crevices and nooks using a toothbrush made of nylon or Coffeetool.
The drip tray is important to keep clean as it is the place where you can collect all coffee waste from each brewing cycle. This could be a breeding ground of bacteria and mold that can affect the taste of your coffee. You should also clean the exterior of your machine frequently to prevent the accumulation of coffee and milk residue.
Think about using a milk system cleanser that is designed to cleanse all components that come into contact with milk. These products are available in most grocery stores. They are also easy to use.
