How to Properly Maintain and Clean an Espresso Coffee Machine Espresso machines use pressure to force water through coffee grounds. This type of brewing makes an even stronger drink than drip coffee. These machines require 9 bars of pressure to extract flavor from the grounds. There are three main types of espresso machines. There are three primary types of espresso machines semiautomatic, manual, and fully automatic. Semiautomatic machines permit you to regulate grinding, tamping and extraction time. They offer a good balance between human control and machine consistency. Easy to use The best espresso machines are simple to use. The best espresso machines have an adjustable thermostat that keeps the water at the right temperature, as well as a pressure pump that increases the amount of water used in each shot. The higher pressure allows grounds to dissolve more quickly and creates a whipped cream of the perfect consistency. These machines have an milk frother to make espresso-based drinks, such as lattes and capspuccinos. The steam-driven electric machines make use of an airtight tank to warm water until it reaches boiling, and then release the pressure to create a shot of espresso. While they're inexpensive and compact they're only able to reach 1-2 bars of pressure, which is less than the ideal 9 bars 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 handles the extraction process, but has to manually grind, measure, and then tamp the beans prior to each cup. This machine is more expensive, however it provides greater control and stability. Jai from Blank Street Cafe says. Full-automatic espresso makers are easier to use than semiautomatic machines because they remove the barista's involvement in the making process. They usually come with grinders that plug into the portafilter. They automatically grind and dosing the beans, and can be adjusted to make different drinks. Some even include a milk hopper, and can create froths and pours milk for you. Easy to clean Espresso machines use higher levels of pressure and heat than drip coffee makers to create the perfect, full-bodied, thick shot.

However it is essential to note that a moderate amount of minerals is necessary to ensure proper extraction. Too much can muddle the taste, while too little could result in a weak and salty cup of coffee.
