Coffee and Espresso Machines

Espresso machines make use of pressure to push water through finely ground and tamped coffee beans. They create a rich and tasty brew.

Experts from the Good Housekeeping Institute recommend models that brew with a minimum pressure of 9 bars to achieve optimal extraction. Beware of companies that claim to offer more pressure than is necessary.

Types

The espresso machine, often called a coffee or espresso maker, produces the highest-quality, concentrated coffee that you enjoy in your favourite cafe drinks using an average of 9 bars of pressure. These machines are equipped with many options, such as temperature control and brew-strength control as well as programmable brewing, and a variety of drink sizes. They may also come with steam wands that are either automatic or manual to create an latte with a texturized milk. There are three main types: semi-automatic, super-automatic and automatic. Each espresso machine comes with its own level and type of automation.

Semi-automatic espresso machines are the most sought-after for specialty coffee shops. This gives baristas full control over the brewing process however it's not as user-friendly as a fully automatic machine.

They were the most common espresso machine type in our lab tests and they provide a good combination of consistency and human control.

Functions
