When it comes to measuring the extraction degree of coffee, there are a variety of theories in the industry. 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 you are not satisfied with the quality of the coffee while ensuring the accuracy of the above steps, then you need to adjust the parameters of your bean grinder.

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.

The significance of adjusting bean grinder

The humidity and storage time of coffee beans are constantly changing, and the wear degree of bean grinder blades has also changed over time, so baristas should adjust the bean grinder regularly to ensure that the ground coffee powder remains perfect.
