What is the appropriate thickness of the bean grinder-coffee bean grinding thickness

The proper grinding degree of coffee powder is very important for making a good cup of coffee, because the extraction of water-soluble substances in coffee powder has its ideal time, if the powder is very fine and steamed for a long time, resulting in excessive extraction, the coffee may be very bitter and lose its aroma. On the other hand, if the powder is coarse and cooked too fast, resulting in insufficient extraction, the coffee will be tasteless because it is too late to dissolve the water-soluble substance in the powder.

Fresh coffee beans are emerald green, which must be roasted and cooked, then ground into powder, and brewed before they can become the coffee sold by the store. good coffee must be full of color, aroma and taste.

Color-the color of the coffee after brewing is best if it is dark brown with a little amber, which means that the coffee beans are cooked properly.

Fragrance-the unique aroma of coffee, the stronger the fragrance is, the longer the aroma is, the better the quality is.

Taste-balanced and thick in the mouth, long-lasting and obvious, is good coffee, but whether the taste is mellow or not is closely related to the method of brewing, such as brewing misses the point.

What is the scale of the XX bean grinder?

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 does not change, the strength of the powder can not be changed.

Remember a little trick: when you find the right powder thickness, twist it with your hand from time to time, pinch it, feel it with your body and write it down as much as possible, so that even if you change the bean grinder, you don't have to rely solely on the scale to judge. If you pinch it with your hand, it will be significantly thicker, which can greatly improve your efficiency.

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, and I will discuss it with you later)
