Introduction to the description of different kinds of Flavor of Coffee Bean

About the fineness of ground coffee beans. As there are so many ways to make coffee, there are many ways to make coffee. Now I would like to introduce to you the reaction of grinding thickness to taste. The thickness of coarse ground caffeine is lower and its acidity is obvious. On the contrary, the alcohol has high thickness and low acidity. Of course, it also has something to do with the time of extraction. The cooking time is long and the thickness of alcohol is high, but the thickness of short alcohol is low. You can arrange and combine according to these two sets of relationships. The high mellow degree mentioned here does not include the situation in which the coffee is scorched.

Introduce to you the method of selecting the grinding thickness of several kinds of instruments. It is recommended to grind the kettle coarsely, because it takes a long time to soak; the mocha kettle and semi-automatic kettle are thinner, but not powdery, but have fine particles; electric drip filtration can be determined according to the taste, if it is thicker, it is finer, if it is lighter, it is thicker.

Manual brewing, siphon pot, if I say medium grinding fineness, I am afraid you think what I said is not detailed. But it must depend on the player's habits and production genre. After playing at this level, Uncle Dou won't talk any more. The uniformity of grinding is a relative index. There is no absolute uniform grinding machine in the world, but the proportion of coarse and fine particles is more or less different. Let's not dwell on this too much.

Friends who grind beans with an electric grinder suggest shaking while grinding. The action is like shaking up and down by drawing lots in a temple, and avoid shaking horizontally. Grind it for a while and then take a look to see if it meets the fineness requirements. If you don't shake it, it will appear that it has already become a face at the bottom, and it is still the case of beans above! Some friends hope to take some pictures so as to be as intuitive as possible. Please allow Uncle Dou to try, it depends on the camera and the shooting effect.

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.

The double-gear bean grinder sets the size of the coffee powder by adjusting each other's height, but don't underestimate this kind of bean grinder. Its structure is extremely precise. Without the double-gear bean grinder, it is impossible to make thick, authentic espresso.

Visual observation of the quality of espresso

Whether espresso is successful or not can only reach 51% accuracy by looking at the flow rate, color or the number of seconds of reading, and it must be tested in person before it is safe. Although the visual method is not very accurate, there is a visual table for reference:
