Do you want to buy your own espresso machine but not sure how to choose from the many espresso machines found in the stores? If you do not know how they work, it is hard to ask the correct questions when considering buying a machine.

Hot water – around 90 degrees centigrade, is forced under pressure through coffee grounds. The pressures can be quite high – in some cases as much as 9 bars. If the coffee is of a high quality and the grind is fine enough, the machine will extract the coffee oils and produce a smooth, creamy shot of espresso.
