Introduction to the matching of grinding thickness of Italian coffee beans

Introduction to Italian Coffee

If you use a coffee cup with a scale, that's great. But you still need to measure the total weight of the coffee to better determine whether the grinder needs to be readjusted. If you use an automatic divider, the total weight of the coffee you make will have an error of about 3G. Since the scale on the cup can help you determine the liquid volume of coffee, you need to spend more energy on measuring the extraction time of coffee.

Let me tell you the importance of these data. Whenever we adjust the coarseness of the bean grinder to + /-1 scale, the extraction time of coffee will change by 4-5 seconds, and the total weight of coffee will have an error of 10g.

Since we use a large bean grinder, the above changes may not be so obvious on a small bean grinder. But this is enough to prove how important the data is in debugging the bean grinder.

When you do this, most brands of bean grinders on the market will store 60g ground coffee powder. According to our experience, you need to store at least 100g of coffee powder in the bean grinder before you can start debugging the machine, and the debugging effect is more obvious. So, you need to make at least three more espresso before you start debugging the bean grinder, and when you're done, you have to make at least five or more cups of coffee. This is very important! The last thing you want to do is go back to work and retest and debug your machine.
