How we test quality of espresso

Our expert tasting panel rate the quality of espresso produced by the machine, taking into account the taste, aroma and appearance of the espresso. We also measure the temperature of the espresso and how quickly it's produced.

How we test ease of use

Our ease-of-use rating takes into account how simple the instructions are to understand and follow and how easy it is to prepare the machine for use. We also assess how straightforward the cleaning and descaling processes are.

How we test energy efficiency

We measure the amount of energy the coffee machine uses to heat up and make coffee. We also check how much energy it uses in standby mode.

How we test quality of cappuccino

If a coffee machine comes with a milk-frothing system, our panel rate the quality of cappuccino, taking into account the taste, aroma and appearance of the cappuccino, as well as how thick the froth is and how well it blends with the coffee. We also assess how easy it is to use and clean the milk frother.

How we test quietness

Our expert lab testers subjectively rate how noisy each coffee machine is when preparing an espresso. This subjective assessment is paired with an objective measurement of the decibel level. A very quiet model will earn itself five stars, while a very noisy machine will only pick up one.

How we test personalisation

Our personalisation rating takes into account how customisable the settings on the coffee machine are so you can tailor drinks to meet your specific tastes. We assess if you can adjust the grind settings, temperature, coffee strength, amount of water dispensed, and whether you can set up profiles for separate users.
