What are the many factors that affect a perfect cup of coffee?

We divide the production process into several elements based on their impact on coffee quality, which facilitates the organization of a large number of materials, not to say that these elements are independent of each other or can be defined separately.

For example, there are many small factors that affect pump pressure, we just assume that they are normal, the valve seal in the machine is intact, and the head seal ring is soft and flexible to ensure that the seal performance is intact. We also assume that the pumps are working properly, and so on. In practice, everything changes at different times. Therefore, instead of fixing our understanding on the elements we divided, we can reorganize the various elements to establish our own espresso making process.

In espresso making practice, when several factors appear at the same time, it is difficult to isolate one factor, and different factors intersect and influence each other. According to Dr. Ernesto llly, there are thousands of possibilities for error, and only one combination gives the best results.

To get a good espresso, you have to think about not just one factor, but all the others and how they relate. Here are some of the most common factors that affect espresso:

1, environmental factors: temperature, humidity, light;

2. Raw material factors: cleanliness and mineral composition of water, freshness of coffee, roasting and formulation of espresso beans;

3, equipment factors: espresso grinder, espresso machine, pump pressure, water temperature, cleanliness;

4, production technology: coffee powder filling tools and skills, extraction time, espresso extraction, grinding degree.
