What is the appropriate thickness of the bean grinder? how much is the thickness of the bean mill?

The scale is just a reference, different brands have different grinding scales, and the performance of the same model bean grinder of the same brand under the same scale is not exactly the same. it is better to understand it this way: the scale just tells you which direction is thick and which is fine. when you find a suitable powder thickness, the role of the scale will show a little bit. The premise is that only your bean grinder, and can not change the beans, the amount of powder remains the same, the strength of the powder can not be changed.

In the case of relatively fine grinding, the powder used overnight has changed? Even after cleaning a large amount of residual powder from the powder outlet at night, there is a phenomenon of increasing extraction time (there is a pressure meter on the machine for reference, and the pressure is really high). Whether the residual powder in the cutter head will have an impact overnight.

Any coffee adjustment is the growth and decline of one or the other! Because the Italian base (espresso) emphasizes rich, balanced, generous and fast! The essence of coffee is extracted in a short period of 20-30 seconds. In a very short time, we have to increase the extraction of coffee by grinding its fineness. We have found that the fineness of espresso powder is close to the size of flour (just a metaphor). In the process of making light appliances, why is the powder similar to the size of granulated sugar? Have you found that the extraction time of single coffee is basically around 2~3min, which is a little longer! According to the principle of growth and decline, grinding thickness needs to go in a rough direction (these are some general concepts, which I will discuss with you later).
