How to Properly Maintain and Clean an Espresso Coffee Machine Espresso machines push water through the coffee grounds using pressure. This type of brewing results in more strength than drip coffee. These machines require 9 bar of pressure to extract flavor from the grounds. Espresso machines are available in three main types. There are three primary kinds of espresso machines that are semiautomatic, manually operated and fully automated. Semiautomatic machines let you control tamping, grinding and extraction time. They offer a good compromise between human control and machine reliability. Simple to use The top espresso machines come with an easy-to-use interface. They have an adjustable thermostat to keep water at the right temperature and a pressure-pump that raises the amount of water per shot. The higher pressure helps the grounds dissolve more quickly and creates a crema with the perfect consistency. These machines also include an milk frother that can make espresso-based drinks like lattes or cappuccinos. Traditional espresso machines powered by steam use an air-tight tank to heat the water until it reaches a boiling point, and then release the pressure in a shot of coffee. They are small and cost-effective however they only allow about 1-2 bars of pressure. This is less than the ideal 9 bars for espresso. Semi-automatic espresso machines work by introducing hot water into an already-ground, pre-tamped portafilter of beans. The barista is responsible for the extraction process but must manually measure, grind and tamp each cup of beans. This machine is more expensive but it gives you more control and stability. Jai from Blank Street Cafe says. Full-automatic espresso machines eliminate the barista from the preparation process, making them much easier to use than semi-automatic models. Many have built-in grinders that connect to the portafilter. They automatically grind and dose the beans, and can be adjusted to make various drinks. Some machines include a milk hopper that can make frothy milk and pour it out for you. Easy to clean Espresso machines make use of higher levels of pressure and heat than drip coffee makers to make the perfect, full-bodied, thick shot. They also have a milk-frothing system that lets you to make cappuccinos as well as lattes. They require more maintenance than drip machines, such as regular cleaning and descaleing.
