Coffee and Espresso Machines

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

Good Housekeeping Institute experts recommend models that brew at 9 bars minimum to ensure an ideal extraction. Beware of manufacturers that boast more pressure than is necessary.

Types

The espresso machine (also called a coffee maker and Espresso maker) creates coffee that is more concentrated, and of higher quality, than your favorite café drinks. It works with an average of nine bars of pressure. They come with a range of options, such as the ability to control temperature and brew strength, programmable brewing and various sizes of drinks. Certain machines might come with manual or automatic steam wands for creating texturized milk to create latte art. There are three main types: semi-automatics, super-automatics and automated. Each comes with its own level of oversight and automation.

The most popular espresso machine model for specialty coffee shops is semi-automatic models. Semi-automatic espresso machines permit baristas to have full control over the brewing process however they are not as user friendly as fully automatic or automated machines.

Functions

Look for a coffee maker with two needles so that you are able to see both the minimum and maximum pressure.

If you want more than espresso, then you should consider one that has different sizes of brew. This includes the ristretto.
