Last Updated: 2025/08/21, * about extraction temperature: according to the depth of baking, the density of beans, flavor characteristics and personal preferences, the temperature can be adjusted in a wide range, generally at 88-92 ℃ as the reference point. * with regard to the extraction scheme: if you need to adjust the extraction scheme, it is recommended that only one variable be adjusted. Because the more variables you adjust at the same time, the more difficult it is to figure out which one the problem is.

* about the extraction temperature:

According to the depth of baking, the density of beans, flavor characteristics and personal preferences, the temperature can be adjusted in a wide range, generally at 88-92 ℃ as the reference point.

* about the extraction scheme:

If you need to adjust the extraction scheme, it is recommended to adjust only one variable. Because the more variables are adjusted at the same time, the more difficult it is to analyze which part of the problem lies.

Coffee powder, such as refined salt, has an obvious sense of granulation.

Siphon pots, such as granulated sugar, can be thickened by half if you use the same bean grinder.

Drip filter and French pressure, the required coffee powder is the thickest, such as coarse sugar, all granular.

In fact, the most important thing is the taste and taste, for this purpose to adjust.

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.
