In the run-up to the test, we defined practical requirements and the following test criteria:
In order to evaluate these criteria, we have defined several tests for the Espresso capsule machines. Several espressos are brewed in these. Before the first run, the commissioning is evaluated and the machines are prepared according to the manufacturer's specifications. In addition, the scope of delivery is checked and the volume of the water tank measured.
When the espresso is brewed, the time and volume required are measured and the handling and user-friendliness are assessed. If other functions or coffee options are available, these are also tested.
Several test persons try and evaluate the finished espresso. Finally, the machines are cleaned and descaled. In addition, the capsules are removed and it is tested whether individual parts of the devices are dishwasher-safe.
In order to rule out errors and to ensure that the devices can withstand the strain of everyday use, each test is carried out in several stages.
The test criteria are given percentages depending on their importance. The final score is then objectively calculated from the test criteria using an algorithm.
Our product selection is based on an observation of the current market. In addition to popular branded products, we also include insider tips in our selection. Criteria such as price and range of functions are an important factor for us. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).
The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.
As soon as new relevant products come onto the market, our test field is extended by these. The new products go through the same test as the already tested devices.
