How to Properly Maintain and Clean an Espresso Coffee Machine Espresso machines use pressure to force water through coffee grounds. This type of brewing produces more strength than drip coffee. The machines require nine bars of pressure to extract the flavor from the ground. There are three primary kinds of espresso machines. They are manual, semiautomatic and fully automatic. Semiautomatic machines let you manage the grinding, tamping, and extraction times. They offer a good balance between machine control and human 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, and a pressure pump that increases the amount of water that is used in each shot. The higher pressure allows the grounds to dissolve faster and creates a crema of the perfect consistency. They also have a milk mixer to make espresso-based drinks, such as lattes and cappuccinos. Traditional electric steam-driven espresso machines utilize an air-tight container to heat the water until it reaches a boiling point, and then release the pressure in a shot of coffee. They are small and affordable, but they only reach only 1-2 bar of pressure. This is less than the ideal 9 bar required for espresso. Semi-automatic espresso machines work by introducing hot water through an already-ground, pre-tamped portafilter of beans. The barista handles the extraction process, but must manually measure, grind and tamp each cup of beans. This machine is more expensive, however it provides greater control and stability. Jai from Blank Street Cafe says. Full-automatic espresso makers are more simple to use than semiautomatic espresso machines because they remove the barista's role in the brewing process. Most come with built-in grinders that are connected to the portafilter. They automatically grind and dose the beans, and can be adjusted to create different drinks. Some even have a milk hopper which can froth and pour milk for you. Easy to clean Espresso machines create a thicker more full-bodied and full-bodied coffee by using higher pressure and heat levels than drip coffee makers. They also come with the milk-frothing mechanism that allows you to make cappuccinos as well as lattes. They require more maintenance than drip machines, including regular cleaning and descaleing.
