Can roasted coffee powder be drunk directly? can coffee powder be brewed directly?

As a result, the speed of grinding and the size of the particles are changed, so that the powder scale, powder quantity and powder pressing strength of the beans appear a little weak, just like you can't put your wife's shoes on your feet. So many foreign restaurants will give fixed beans with a fixed bean grinder, in order to ensure the stability of its grinding effect as far as possible, I think it can best increase the stability, when you use the same kind of beans, find the scale, determine the amount of powder, with a force that you think is more comfortable, if you can make a decent cup of esp, then you are basically done. The reason why it is said that the powder pressing strength adjustment can increase stability, because the scale and powder loading, as well as the beans themselves will have a certain small error due to the environment. And this error, in most cases, can be improved by the weight of pressing powder to achieve a stable extraction effect, but that is for my beans, my bean grinder, my powder thickness, my powder strength, these links are closely linked and can have a direct impact, when you change one of them, the others have to be changed as well. In principle, we load more coarse powder and less fine powder, of course, you can fix what you think is the ideal amount of powder, because the powder quantity and scale are relatively controllable (compare the numerical value, the scale is how much, the amount of powder is a few grams) for example, I am used to using 9g for a single serving and 16g for a double portion.

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.

French filter press, plug air, drip filter or mocha pot do not require high fineness of coffee powder. Knife milk grinder (commonly known as bean chopper or propeller grinder) can not adjust the scale, but to adjust the size of coffee powder according to the length of time, the size of coffee powder is uneven, so it is not suitable for making espresso. It is generally believed that as long as you have an espresso machine, you can make delicious Italian coffee, which is only half right, and the other half depends on a more sophisticated double-gear bean grinder. The lower gear of this bean grinder is connected to a powerful motor, providing a force for high-speed rotation, while the upper gear is connected to the scale and twisted in the reverse clockwise direction, the reading of the scale is getting smaller and smaller, and the upper gear is falling, narrowing the distance between the upper gear and the lower gear. This means that the finer the coffee powder is ground. If the upper gear is twisted in the clockwise direction, the larger the scale value is, the higher the upper gear is and the larger the distance between the upper gear and the lower gear is, so the coffee powder is thicker.

Double-gear bean grinder is to adjust each other's height to set the size of coffee powder, do not underestimate this kind of bean grinder, its structure is incomparably precise, without double-gear bean grinder, it is impossible to make thick, authentic espresso.
