How to Properly Maintain and Clean an Espresso Coffee Machine Espresso machines use pressure to push water through coffee grounds. This method of brewing produces an even stronger drink than drip coffee. These machines require nine bars of pressure in order to extract the flavor from the ground. There are three types of espresso machines . There are three primary kinds of espresso machines semiautomatic, manual and fully automated. Semiautomatic machines let you manage the grinding, tamping, and extraction times. They provide a great balance between machine control and human consistency. Easy to use The top espresso machines are easy to use. They come with an adjustable thermostat that maintains water at the ideal temperature, and a pressure pump that increases the amount water per shot. The higher pressure allows the grounds to dissolve faster and produces a crema with the perfect consistency. These machines also include an milk frother that can make espresso-based drinks like lattes and cappuccinos. Traditional electric steam-driven espresso machines make use of an air-tight tank to heat the water until it is at a boiling point, and then release the pressure in a shot of coffee. While they're affordable and compact they're able to only deliver only 1-2 bars of pressure which is less than 9 bars required for espresso. Semi-automatic espresso machines infuse hot water into a portafilter filled with beans that have been ground and pretamped. The barista handles the extraction process, but has to manually measure, grind and tamp each cup of beans. This machine is more expensive, but it offers greater control and stability. Jai from Blank Street Cafe says. Full-automatic espresso machines completely remove the barista from the brewing process, making them easier to use than semi-automatic models. Many have built-in grinders that connect to the portafilter. They automatically grind and dose the beans, and can be adjusted to make various drinks. Some even come with a milk hopper that can do the frothing and pouring for you. Easy to clean Espresso machines use greater pressure and heat than drip coffee makers to make the perfect, full-bodied, thick shot. They also include the milk frothing system which allows you to make lattes and cappuccinos. This means that they require more regular maintenance than a drip machine which includes descalers and regular cleaning. The good news is that most espresso machines are easy to clean. Some models on our list are designed to make this process simpler. Most espresso machines have a portafilter. It holds the grounds of coffee during the brewing. Some models have a grouphead which is a collection of pieces that do the extraction. To keep these components free of grit and gunk it is necessary to backflush your machine on a regular basis. This involves cleaning and brushing the portafilter, locking it and running the brew cycle multiple times. Backflushing is routinely done in many coffeehouses, but at home, it should be done once every week. It is best to use softened or filtering water, since it will reduce mineral accumulation and the need to remove scale. However it is essential to note that a moderate amount of minerals are required to ensure proper extraction. Too much mineral can ruin the taste. A lack of minerals can result in an unsavory, salty coffee. Making sure your machine is properly maintained will ensure that it continues to perform well and taste great for the duration of time you have it. Easy to maintain An espresso machine is a stunning piece of equipment that lets you to serve a wide variety of coffee drinks. A carafe-style coffee maker can provide the same results however an espresso machine needs more pressure and temperatures. To achieve this, it must be maintained and cleaned properly.

You'll also want to scrub the group screen and the nooks and cranny with a nylon brush or Coffeetool. The drip tray is essential to wash regularly since it holds all the coffee waste after each brewing cycle. It can also become an ideal habitat for bacteria and mold, which can affect the flavor of your coffee. In addition, you should clean the exterior of your machine on a regular basis to prevent milk and coffee residue from accumulating. You should also consider using a milk system cleaner that is safe for food and designed to clean any components that come into contact with milk.
