How to Properly Maintain and Clean an Espresso Coffee Machine Espresso machines push water through the coffee grounds by using pressure. This type of brewing produces a stronger drink than drip coffee. These machines require 9 bar of pressure to extract flavor from the grounds. There are three primary types of espresso machines. There are three types of espresso machines that are semiautomatic, manually operated and fully automated. Semiautomatic machines permit you to control tamping, grinding and extraction time. They are a great compromise between machine control and human reliability. Simple to use The top espresso machines are simple to use. They come with an adjustable thermostat that keeps water at the right temperature and a pressure-pump that increases the amount of water per shot. The increased pressure helps the grounds dissolve more quickly and produces a crema with the perfect consistency. The machines also come with a milk frother for making espresso-based drinks such as lattes and cappuccinos. Traditional espresso machines powered by steam utilize an airtight tank to heat the water until it is at a boiling point, then releases the pressure in a shot of coffee. Although they're compact and affordable they're only able to reach 1-2 bars of pressure, which is less than 9 bars required for espresso. Semi-automatic espresso machines function by infusing hot water through an espresso portafilter that has been pre-ground and tamped of beans. The barista is the one responsible for the extraction process, but must manually measure the amount of beans, grind and tamp each cup of beans. While this style of machine is more expensive than others however, it gives more control and stability, says Jai of Blank Street Cafe. Full-automatic espresso machines remove the barista from the coffee making process, which makes them easier to use than semi-automatic models. Most have built-in grinders that plug into the portafilter. They automatically grind and dosing the beans, and are often altered to create various drinks. Some machines include an hopper for milk that can blend milk and pour it out for you. Easy to clean Espresso machines utilize higher pressure levels and heat than drip coffee makers to make an intense, full-bodied shot. They also come with a milk-frothing system that allows you to make cappuccinos and lattes. They require more maintenance than drip machines, including regular cleaning and descale. Fortunately, espresso machines are simple to clean. Some of the models on our list are designed to make cleaning easier. The majority of espresso machines have a portafilter to hold the grounds of the coffee while it is the brewing. Some models also have a group head that is a set of components that perform the actual extraction. To keep these pieces free of gunk and grit, you'll need to clean your machine every week. This means washing and brushing the group head, and then locking the portafilter, and then running the brew process several times. Many coffeehouses backflush their machines every day but home owners should only need to do it once a week. It is best to use softened or filtering water, since it can reduce the accumulation of mineral and the need to descale. It is important to keep in mind that a small amount of water is needed for extraction. Too much can muddle the flavor, whereas too little could result in the cup being weak and salty of coffee. Maintaining your machine will ensure it remains in good working order and taste fantastic for as long as you own. Easy to maintain An espresso machine is an amazing piece of equipment which allows you to serve a diverse variety of coffee drinks. But, unlike the typical carafe maker, an espresso machine requires a greater amount of pressure and temperature to produce the desired results.

This can become an ideal habitat for bacteria and mold that can affect the taste of your coffee.
