One of the questions often asked in the coffee industry is "how often should I clean the coffee machine?" The answers are varied, some say once a day, others say once a week, and still others say according to the amount of coffee. But does anyone really know the answer to this question? None of these answers is supported by public research. To answer this question, the authors conducted an experiment to study the relationship between the cleaning frequency of an espresso machine and the taste of coffee. First of all, in this experiment, the factors that may affect the taste of coffee are:

The consistency of the quality and quality of roasted coffee beans, the consistency of baristas' technology and technology, the amount of coffee used, the degree of grinding of coffee beans, the ratio of coffee to water, the extraction time, the ability and reliability of the cup judges, and the performance of the espresso machine.

In order to determine this problem, the experiment must be in strict accordance with the experimental requirements, there is a group of coffee machines can not be cleaned at all. In the course of the experiment, we must try our best to control other conditions to ensure that the cleanliness of the coffee machine is the only variable that affects the taste of coffee, so the experiment must ensure strict requirements.
