How we test coffee machines

15 May 2025

Taste

Overall
Espresso (using capsules)
Cappuccino

How we test taste

Our expert tasting panel rate the quality of espresso produced by the machine, taking into account the taste, aroma and appearance of the espresso. 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.

Quality of espresso

Overall
Speed of making an espresso
Temperature of espresso

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.

Ease of use

Overall
Instructions
Preparing the machine
Cleaning
Descaling

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.

Energy efficiency

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.

Machine performance

How we test machine performance

We test how quickly the machine makes espresso, how hot the coffee is and how well it froths milk, if the coffee machine comes with a milk frothing system. For machines that can make two espressos at once, we also measure the volume and temperature of the coffee in each cup to see if you end up with two evenly matched espressos.

Quality of cappuccino

Overall
Milk frothing
Ease of using milk frother

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.

Quietness

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.
