In the run-up to the test, we defined practical requirements and the following test criteria:
- Yoghurt quality
In order to be able to evaluate these criteria, we have defined several tests for the yoghurt makers. In these tests, all devices must prepare the maximum possible amount of yoghurt. The devices are set up and prepared according to the manufacturer's specifications. For the preparation of the yoghurt you Need about 1-2 teaspoons of 3.8% yoghurt and about 130-140 ml 3.5% milk. If necessary, heat the milk before use. The yoghurt containers are filled and prepared in the machines for 9 hours. The heat of the yoghurt makers is checked by means of a thermal imaging camera. During the process, user-friendliness and handling are also assessed. Finally, the devices are cleaned by hand or in the dishwasher.
In order to eliminate errors and to ensure the load of everyday use, each test takes place in several rounds.
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.
