Master the correct adjustment method of Italian bean grinder a good bar barista must have skills

It's a good choice to use an Italian coffee grinder in a coffee shop or at home. As long as you set the right data, you will have an unprecedented coffee experience, and the coffee you make will have constant quality and perfect taste. How to set up an electronic grinder when using a new variety of coffee beans, and how to maintain the constant quality of coffee. At the same time, I will teach you how to keep your bean grinder at its best at all times. Of course, there are subtle differences between each bean grinder. Today we are using a Mazzer Italian coffee grinder.

Preparation before debugging the Italian coffee grinder:

Suppose you have just bought a new coffee bean and can't wait to start debugging your bean grinder. Here are some things you should do:

[clean up]

You must make sure that there is no residual coffee powder or beans in your bean grinder. If you find that there are still coffee beans in the grinding gear, you can remove the bean barn, cover the interface between the bean warehouse and the grinding gear, and turn on the switch to clean up the coffee beans left in the coffee mill. If you think there is coffee powder left in the coffee mill, you can open the control panel and take a closer look at the inside of the bean grinder. A 100% clean coffee mill must ensure that there is no coffee powder left in the powder trough. You can also wipe the funnel-shaped meter with a dry cloth. Only by doing the above steps can you ensure that your coffee is ground neatly and neatly, and avoid the coffee beans or coffee powder left in the coffee mill from affecting the taste of the coffee.

[preheating]

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, I will show you how to debug the powder quantity in detail.

[test]

Now we officially begin to debug 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 we also rule out other factors such as the water circulation system and water temperature of the coffee machine, so you should also make sure that the coffee machine is set up perfectly before that.
