How to Properly Maintain and Clean an Espresso Coffee Machine Espresso machines force water through the coffee grounds by using pressure. This type of brewing makes an even stronger drink than drip coffee. The machines require nine bars of pressure in order to extract the flavor from the ground. There are three kinds of espresso machines. There are three major kinds of espresso machines that are semiautomatic, manually operated and fully automatic. Semiautomatic machines allow you to control the grinding, tamping and extraction time. They provide a balance between human control and mechanised consistency. Simple to use The top espresso machines are easy to use. The top espresso machines have an adjustable thermostat to keep the water at the correct temperature, as well as a pressure pump that increases the amount of water used in each shot. The higher pressure helps the grounds dissolve faster and produces a creamy crema with the right consistency. These machines have an milk frother to make espresso-based drinks such as lattes and capspuccinos. Traditional espresso machines powered by steam utilize an airtight tank to heat the water until it reaches a boiling point, which releases the pressure in a shot of espresso. Although they're compact and affordable they're only able to reach only 1-2 bars of pressure which is less than the recommended 9 bars for espresso. Semi-automatic espresso machines infuse hot water into a filtration system that is filled with pre-ground and pretamped beans. The barista is in charge of the extraction process, but must manually measure, grind and tamp each cup of beans. Although this kind of machine is more expensive than other machines it offers greater control and stability, says Jai of Blank Street Cafe. Full-automatic espresso machines completely remove the barista from the espresso brewing process, making them more user-friendly than semi-automatic models. They usually come with grinders that are connected to the portafilter. They automatically grind and dosing the beans and can be adjusted to produce different drinks. Some machines include an hopper for milk that can froth milk and pour it out for you. Easy to clean Espresso machines make use of higher pressure and heat than drip coffee makers to produce an intense, full-bodied shot. They also have a milk-frothing system that allows you to make cappuccinos and lattes. They require more care than drip machines, including regular cleaning and descaleing. The good news is that most espresso machines are simple to clean. Several models on our list were made to make cleaning easier. The majority of espresso machines have an in-line portafilter, which holds the grounds of coffee while brewing. Some models feature a grouphead that is a collection of parts that perform the extraction. To ensure that these parts are free of grit and gunk it is necessary to clean your machine on a weekly basis. This means cleaning and brushing the portafilter, locking it, and running the brew cycle several times. Many coffeehouses backflush their machines every day but home owners need to only do it once per week. It is best to use softened or filtered water, as it will reduce mineral accumulation and the need to descale. It is important to remember that a small amount of water is required for extraction. Too much mineral can ruin the flavor. Too little can result in an unsavory, salty coffee. Maintaining your machine will ensure it remains in good working order and taste great for as long as you own.
