Coffee and Espresso Machines

Espresso machines utilize pressure in order to force water into finely ground and tamped beans. They create a rich, delicious cup.

Good Housekeeping Institute experts recommend models that use 9 bars minimum for a perfect extraction. Beware of brands that advertise more pressure than is necessary.

Types

The espresso machine, also called a coffee or espresso maker, makes the more concentrated, premium coffee that you like in your favourite cafe drinks using an average of 9 bars of pressure. These machines typically have many features, such as temperature and brew strength control with programmable brewing as well as various sizes of drinks. They may also come with manual or automatic steam wands to create an latte with a texturized milk. There are three kinds of latte art: semi-automatic, super-automatic and automatic. Each comes with its own level of supervision and automation.

The most well-known espresso machine type for specialty coffee shops is the semi-automatic model. Semi-automatic espresso machines permit baristas to control the brewing process, but aren't as user-friendly as fully automatic or automated machines. To get the most perfect espresso shot, you need to grind the beans, then fill the portafilter and tamp it down, and adjust the extraction time.

Automated machines come with built-in mills that measure and tamp your grounds. They automatically pour out enough water to extract espresso, and typically have the capacity to programate the size of the beverage. They were the most frequent espresso machine type in our lab tests and they provide a good balance of consistency and human control.

Functions

You'll need a reservoir to hold the water you use for making coffee, whether you select a steam-driven or pump-driven machine. You'll also have a heating device that heats the water to create the pressure necessary to extract the coffee from the grounds.

When the brew lever is lifted, it triggers the water inlet cam, which seals the pre-infusion valve so only intensely pressurized hot water can flow through the portafilter into ground coffee. The water will take about 25 seconds before it turns into espresso.

The hot-water tubing, also known as the insulated tubing, is a tube that runs from the reservoir to the spout on the top of your machine. The resistance heating element will heat the water as water flows through the aluminum tube and metal warming plate.

When the spout has been switched on, you'll need to place your cup under the spout in order to capture the espresso as it is pushed through the portafilter into your cup. The coffee maker also has an steam wand you can use to heat and froth the milk for espresso-based beverages such as cappuccino and lattes.

Automated machines take the guesswork out of the brewing process. They operate with just one button they can be programmed and grind and measure beans for you and grind them down. In our Lab tests, they tend to perform best due to their being user-friendly and don't require an extensive amount of user expertise.

Materials

Look for a button that can be used to turn on the steam wand, which is used for creating the latte art and frothing the milk.

Find an espresso maker that has two needles so that you are able to see both the maximum and minimum pressure.

If you're looking to create more than espresso, you should choose a machine that has different sizes of brew, including the ristretto.
