Qianjie-A brief introduction to the grindability of hand-brewed coffee

Different bean grinders have different adjustment dials, so you should check the model of the coffee grinder and read the instructions carefully to determine the direction and strength of the dial. In general, if you keep in the habit of checking the settings of the bean grinder, you only need to make very small adjustments. As long as you move the turntable within 3 mm, you can change the thickness of the powder. Although 3 mm is a very small number, the grinding time of the same coffee beans will change by 3-5 seconds.

Bean grinder calibration parameters reference:

Practical parameters of small Fuji scale:

# 4.5 (suitable for light taste or reducing the bitterness of deep-baked bean coke)

# 3.5 roast 4 (moderate shade, suitable for light baking, medium baking or medium deep baking)

# 3 (suitable for heavy taste, but not for deep-baked beans)

Practical parameters of Little Eagle scale:

# 4 (suitable for light taste or reducing the bitterness of deep-baked bean coke)

# 3 roast 3.5 (moderate shade, suitable for light baking, medium baking or medium deep baking)

# 2.5 (suitable for heavy taste, but not for deep-baked beans)

The smaller the bean grinder is, the finer the grinding is, and the thicker the coffee is. As far as the Xiaofei bean grinder, which is the most commonly used by hand, the scale # 3.5 is the most suitable for hand flushing. If it is further thickened to the scale # 4, it can also be used to flush heavy roasted beans or shallow roasted coffee beans by hand. But the extraction rate is too low, there should be insufficient extraction, taste is too thin heart preparation.

Hand flushing with scale # 3 is the safest and is suitable for light, medium and deep baked popular tastes, but deep baked beans may be too bitter if they are washed by hand with a scale of # 3. If you adjust the fine half degree to # 2.5, the extraction rate will be about 0.5%-1.5% higher than # 3, the amplitude is very large, the room for tolerance for mistakes becomes smaller, the water temperature is too high or the extraction time is too long, and it is easy to flush out bad coffee with a slight error.

Knowledge: the thickness of coffee powder is related to the amount and speed of coffee ingredients released when brewing coffee. Generally speaking, the thickness of coffee powder can be divided into five grades: very fine powder, fine powder, medium powder, coarse powder.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
