Coffee and Espresso Machines

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

Experts at the Good Housekeeping Institute recommend models that brew with a minimum pressure of 9 bars in order to get the best extraction. Beware of companies who claim they use more pressure than necessary.

Types

The espresso machine, often called a coffee or espresso maker, Buy Espresso Makers produces the most concentrated, high-quality coffee that you enjoy in your favourite cafe drinks using an average of 9 bars of pressure. These machines usually have numerous features such as temperature and brew strength control as well as programmable brewing and multiple sizes of drinks.
