How to adjust the calibration of Italian grinder-Coffee grinder how to adjust the thickness

The brands of the mill are different, and the thickness of the powder ground by the same scale marked by each brand of mill is different, which can only be adjusted from your brewing method. At the same brewing temperature, the extraction time can be longer if the powder is coarser, and the extraction time can be shorter if the powder is finer. Basically speaking, regardless of the variety, siphon, hand made fine granulated sugar size coffee powder is more appropriate, semi-automatic Italian machine is required to grind to flour coffee powder

The adjustment of the electronic bean grinder is mainly aimed at two variables, the amount of powder and the degree of grinding. These two variables are mutually dependent, and changing one of them changes the other.

Ordinary electronic bean grinder will adjust the grinding and grinding time of the bean grinder according to the preset grinding amount (please note that the grinding machine adjusts the grinding amount according to time rather than weight). If you are not satisfied with the quality of your coffee, the first thing you need to do is determine whether the problem is with the amount of powder or the degree of grinding.

In general, the distance between the cake and the water outlet after correct weight, smoothing and pressing should be 5-6 mm. If the cake height is not within this range, you should try to adjust the amount of flour (that is, grinding and flour time) of the grinder. When adjusting the amount of powder, the amplitude of each adjustment should be between 0.2 and 0.3 seconds. After each adjustment, you need to re-test the quality of coffee.

Every small change in the details of the grinder will have a huge impact on the overall quality of the coffee. Therefore, as a barista, you should re-measure and adjust the grinder every day to ensure the perfect quality of coffee.

To master the proportion of coffee powder, you can practice using a constant amount of coffee powder (for example, 18 grams) and try to mix different coffee weights, and then compare the differences between the taste, purity and body of various proportions. You need to decide the final gouache ratio according to your personal preference.

Only through practice and trial and error can you make espresso that really suits you.
