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 results in an even stronger drink than drip coffee. These machines require nine bars of pressure to extract the flavor from the ground.

They have an adjustable thermostat that keeps water at a consistent temperature, and a pressure pump that increases the amount water used per shot. The increased pressure makes the grounds to dissolve faster and produces a crema with the ideal consistency.

Traditional espresso machines powered by steam utilize an airtight tank to heat the water until it reaches the boiling point. It then releases the pressure into a shot of coffee. Although they're compact and affordable, they can only reach the pressure of 1-2 bars, which is less than 9 bars for espresso. Semi-automatic espresso machines dispense hot water into a portafilter that is filled with pre-ground and pretamped beans. The barista is in charge of the extraction process, however they must manually grind, measure, and then tamp down the beans prior to each cup. This machine is more expensive but it gives you more control and stability. Jai from Blank Street Cafe says.

Most have built-in grinders that plug into the portafilter. They automatically grind and dose the beans, and can be adjusted to make various drinks.
