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 produces a stronger drink than drip coffee. These machines need 9 bars of pressure to extract flavor from the coffee grounds. Espresso machines are available in three main types. They are manual, semiautomatic and fully automated. Semiautomatic machines let you control grinding, tamping and extraction time. They are a good balance between machine control and human reliability. Easy to use The best espresso machines are easy to use. They feature an adjustable thermostat to keep the temperature of the water at a suitable level as well as a pressure pump which increases the amount of water per shot. The higher pressure allows grounds to disintegrate faster and creates a crema of the perfect consistency. These machines also include a milk frother to make espresso-based drinks such as lattes and cappuccinos. Traditional espresso machines powered by steam make use of an air-tight tank to heat the water until it reaches boiling point. It then releases the pressure in a shot of coffee. While they're inexpensive and compact they're able to only deliver 1 or 2 bars of pressure, which is less than the ideal 9 bars required for espresso. Semi-automatic espresso machines dispense hot water into a portafilter that is filled with beans that are pre-ground and pretamped. The barista is the one responsible for 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. Most have built-in grinders that connect 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 create froths and pours milk for you.

They also come with the milk-frothing mechanism that allows you to make cappuccinos and lattes.
