Italian coffee grinder thickness and scale adjustment
Adjustment of thickness and scale of Italian coffee grinder
Start extracting coffee. If there is no scale on your coffee cup, you need to measure the total weight of the coffee (28-32g). Measuring weight can help you determine whether coffee extraction is fast or slow, which is much more accurate than visually measuring the flow rate of coffee. This is not to say that visual observation is useless, but at least the numbers don't lie to you.
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.
