Coffee and Espresso Machines

Espresso machines make use of pressure to force water through finely ground and tamped coffee beans. They make a rich, flavorful brew.

Good Housekeeping Institute experts recommend models that can be brewed with a minimum of 9 bars for a perfect extraction. Beware of manufacturers that claim to use higher pressure than necessary.

Types

The espresso maker (also called a coffee maker and espresso coffee machine maker) produces coffee that is more concentrated, and of higher quality, than your favorite cafe drinks. It makes use of an average of nine bars of pressure. These machines usually have a variety of features like temperature control and brew strength with programmable brewing as well as different sizes of drinks. Some machines can have steam wands that are either automatic or manual for creating texturized milk for artwork with latte. They are available in three main types of espresso machines, including semi-automatic, automated, and super-automatic models. Each espresso machine comes with its own degree and type of automation.

Semi-automatic espresso machines are most popular for specialty coffee shops. Semi-automatic espresso machines permit baristas complete control over the brewing process, but aren't as user-friendly as fully automated or automated machines.

Automated machines have an integrated grinder that can measure and mill the grounds for you. They automatically disperse enough water to extract espresso and often have a programmable beverage size. In our tests in the lab, they were the most favored type of espresso machine. They offer a good combination of consistency and manual control.

Functions
