How to Properly Maintain and Clean an Espresso Coffee Machine Espresso machines make use of pressure to push water through coffee grounds. This method of brewing produces an even stronger drink than drip coffee. These machines need 9 bars of pressure to extract flavor from the grounds. Espresso machines are available in three primary kinds. They include manual, semiautomatic and fully automatic. Semiautomatic machines allow you to manage grinding, tamping and extraction time. They are a great balance between machine control and human consistency. Simple to use The best espresso machines are easy to use. The top espresso machines feature an adjustable thermostat that keeps the water at the right temperature, and a pressure pump that increases the amount of water in each shot. The increased pressure makes the grounds dissolve faster and produces a creamy crema with the perfect consistency. The machines are equipped with a milk frother to prepare espresso-based drinks, such as lattes and capspuccinos. The steam-driven electric machines utilize an airtight tank that heat water until it's boiling point, and then release the pressure into a shot of espresso. Although they're compact and affordable however, they only have the pressure of 1-2 bars, which is less than 9 bars for espresso. Semi-automatic espresso machines function by introducing hot water into an already-ground, pre-tamped portafilter of beans. The barista handles the extraction process, however they must manually grind, measure and tamp the beans prior each cup. While this model is more expensive than other machines it offers greater control and stability, says Jai of Blank Street Cafe. Full-automatic espresso machines remove the barista from the preparation process, making them much more user-friendly than semi-automatic models. Most have built-in grinders that click into the portafilter. They automatically grind and dose the beans, and can be adjusted to create different drinks. Some even include a milk hopper, and can create froths and pours milk for you. Easy to clean Espresso machines utilize greater pressure and heat than drip coffee makers to make the perfect, full-bodied, thick shot. They also come with the milk frothing system which allows you to make lattes and cappuccinos. As such, they require more regular maintenance than a drip machine that includes descalers and routine cleaning. Fortunately, espresso machines are easy to clean. A few models on our list are designed to make this process simpler. Most espresso machines come with a portafilter to hold the grounds of the coffee while it is brewing. Some models also come with a group head that is a set of components which perform the actual extraction. Backflushing your machine regularly will keep these parts clean and free of grit and gunk. This involves cleaning and brushing the portafilter, locking it, and running the brew cycle multiple times. Backflushing is a common practice in a lot of coffeehouses, however at home, it should only be done once every week. It is recommended to use softened or filtering water, as it reduces the accumulation of minerals and the need to descale. However it is important to note that a reasonable amount of minerals is required for proper extraction. Too much mineral can overwhelm the flavor. A lack of minerals can result in weak, salty coffee. Maintaining your machine in good condition will ensure that it will continue to function properly and taste great for the duration of time you own it. Easy to maintain An espresso machine is an impressive piece of equipment that allows you to serve a broad range of coffee drinks. A carafe coffee maker can achieve the same result but an espresso maker needs more pressure and temperatures. To achieve this, it has to be maintained and cleaned properly. Fortunately, you don't need to be a professional in order to keep your espresso machine running smoothly. You'll need to clean the gasket at least once a week. This is where coffee oils accumulate and could cause the bitter taste of the espresso that has gone rancid. Backflush your group using a water-espresso machine cleaner solution. You'll also need to scrub the screen of your group, including the crevices and nooks using a toothbrush made of nylon or Coffeetool. It is also essential to clean the drip tray on a regular basis, as it collects the coffee waste that comes from each brewing cycle. This can be an ideal place for the growth of bacteria and mold that could affect the taste of your coffee. You should also clean your machine's exterior regularly to avoid the build-up of milk residue and coffee. You should consider using a milk system cleanser which is designed to clean every component that comes in contact with milk. These products can be found in most grocery stores. They are also easy to use. Repairable and simple A coffee maker or espresso machine is an extremely useful appliance for a home or office.
