There are a variety of theories in the industry to measure the extraction degree of coffee. In general, the first drop of coffee from the handle should be between 4 and 6 seconds, with a texture like melted chocolate dripping on the back of a spoon. The standard extraction rate should be 25-30 milliliters of coffee every 25-30 seconds.
If the extraction time of coffee is less than 25 seconds, the degree of grinding of coffee powder is too coarse, the speed of water passing through coffee powder is too fast, and you need to adjust the bean grinder to make the grinding degree finer. If the extraction time is more than 35 seconds, the degree of grinding of the coffee powder is too fine, the speed of water passing through the coffee powder is too slow, and you need to adjust the bean grinder to make the grinding a little thicker. If you are not satisfied with the quality of a cup of coffee, before adjusting the bean grinder, the first thing you should do is to make a new cup of coffee with the same degree of grinded coffee powder, this time you should focus on improving your serving, smoothing and crushing techniques. because all of the above steps may lead to excessive or inadequate extraction of coffee. If the quality of the coffee is still not satisfactory while ensuring the accuracy of the above steps, then you need to adjust the parameters of your bean grinder.
Remember a little trick: when you find the right powder thickness, twist it or pinch it with your hand from time to time, 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 obviously thicker, and it can greatly improve the efficiency.
What matters is what kind of powder the coffee machine is suitable for. Because the finer the powder, the higher the pressure on the coffee machine. As long as the machine allows. The greater the amount of pressing powder, the finer the powder, the better. If the coffee powder is ground to a certain scale, the coffee machine will obviously slow down or stop producing coffee. Then the powder will be fixed above this. From now on, just grind it like this. This is done to drink good coffee. The essence of drinking coffee. If for the safety and longevity of the coffee machine. The coarser the grinding
The brand of the mill is different, and the thickness of the powder from the same scale identified by each brand is different, which can only be adjusted from your cooking method. At the same cooking temperature, the powder is thicker, the extraction time can be longer, the powder is finer, and the extraction time can be shorter. Basically, regardless of the variety, siphon and hand-made coffee powder the size of granulated sugar is more suitable.

The semi-automatic coffee machine features that the water extracted from the coffee is constant temperature, no matter how often the espresso is made; the pump pressure is stable during the extraction process; the espresso machine had better have a prepreg section; the steam is constant pressure, dry and easy to operate; although the semi-automatic coffee machine does not change from a grain of coffee beans to a grain of coffee like a fully automatic coffee machine.

Hand grinding machine grinding degree from coarse to fine-mazzer bean grinder thickness adjustment manual most without scale, electric to commonly used little eagle little flying horse is more common, siphon pot is generally 3 degrees, hand 4-5 degrees (depending on the powder thickness of some differences) method pressure 5 degrees, mocha pot 2 degrees, but the relative value should be adjusted according to their own habits and bean grinder conditions. The amount of powder is usually siphoned 10-12 per person.
