How to adjust the scale of Italian bean grinder-electronically controlled Italian bean mill calibration

Determine the direction of adjustment you need (finer or thicker). Make sure there are enough coffee beans in the warehouse, and the valve between the warehouse and the sharpening knife is opened so that the coffee beans can fall smoothly into the grinding area.

Turn on the grinder for 10 seconds and discard the coffee powder (these are coffee powders that have not been adjusted).

Use the coffee powder to make a cup of coffee to ensure the accuracy of the steps of serving, flattening and pressing powder. The traditional method of making espresso (Ristretto) uses a water / flour ratio of 1:1 (i.e. 18 grams of coffee powder is used to make 18 grams of coffee) or 1:2 (i.e. 18 grams of coffee powder is used to make 36 grams of coffee), while a regular espresso uses a water / powder ratio of 1:2 (i.e., "Normale"). Test the quality of the coffee and the extraction time. Constantly adjust the dial to make the powder reach a perfect thickness.

In order to better ensure the quality of coffee and the reliability of data debugging, you need to preheat the bean grinder in advance. Compared with the preheated bean grinder, the unheated bean grinder will seriously affect the quality of the coffee. So before you start the test, you'd better make four cups of espresso from the coffee beans you bought and preheat them on the machine. Instead of relying on the automatic quantifier that comes with the machine, you'd better manually adjust the amount of powder to meet the standard you want. We'll show you how to adjust the powder quantity in detail later, and we use this data when making espresso based on espresso and most single espresso in the store, but if you use different varieties of coffee beans, the data will vary accordingly. We will also make adjustments according to the coffee machine brand and handle capacity, so if you encounter a similar situation, you also need to adjust your bean grinder in time.

The time of coffee extraction is very important to the quality of coffee. The extraction time required to achieve the same total weight of coffee is mainly affected by two factors: the barista's production skills and the setting of the coffee mill. If your barista can keep the level constant each time you make it, then you can rule out the effect of production skills on extraction time. The only remaining factor is the setting of the coffee mill. You should note that here we also rule out other factors such as the coffee machine water circulation system and water temperature, so before that, you should also make sure that the coffee machine setting is perfect.
