Bean grinder powder adjustment-how much thickness is appropriate for coffee grinder scale adjustment details

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. After that, we will introduce you in detail how to debug the powder quantity and now we have officially started debugging the bean grinder. You need to prepare your own electronic scale, because we will unify the dose of each powder. I will also tell you some of the barista's skills when using the bean grinder to make sure that your debugging of the bean grinder is accurate enough.

The data we use comes from training courses for our internal employees. I'll tell you how we got the data. Here, I won't spend too much space on why we choose these data, because in the end, what you are after is your own exclusive formula, and this formula is best suited to your taste. But if you are a beginner, please study the data we give! The following data are used in making an espresso: the weight of coffee powder is 22g, the total weight of coffee is 36-38g, and the extraction time is 28-32 seconds.

We use this data when making espresso based on espresso and most single espresso in the store, but the data will vary if different varieties of beans are used. 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.
