Coffee automatic grinder, the bigger the scale, the finer the powder?-which is better for coffee 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 3mm is a very small number, the grinding time of the same coffee beans will change by 3-5 seconds to determine the direction you need to adjust (finer or thicker). Make sure there are enough coffee beans in the warehouse, and the valve between the warehouse and the sharpening knife is opened so that the coffee beans can fall smoothly into the grinding area.

Turn on the grinder for 10 seconds and discard the coffee powder (these are coffee powders that have not been adjusted).

Use the coffee powder to make a cup of coffee to ensure the accuracy of the steps of serving, flattening and pressing powder. The traditional method of making espresso (Ristretto) uses a water / flour ratio of 1:1 (i.e. 18 grams of coffee powder is used to make 18 grams of coffee) or 1:2 (i.e. 18 grams of coffee powder is used to make 36 grams of coffee), while a regular espresso uses a water / powder ratio of 1:2 (i.e., "Normale"). Test the quality of the coffee and the extraction time. Constantly adjust the dial to make the powder reach a perfect thickness.

When you do this, most brands of bean grinders on the market will store 60g ground coffee powder. According to our experience, you need to store at least 100g of coffee powder in the bean grinder before you can start debugging the machine, and the debugging effect is more obvious. So, you need to make at least three more espresso before you start debugging the bean grinder, and when you're done, you have to make at least five or more cups of coffee. This is very important! The last thing you want to do is go back to work and then retest and debug your machine when you need to decide whether to re-clean the coffee mill. In order to ensure the quality of coffee, if your debugging range is more than 2 scales, you need to thoroughly clean your bean grinder. Although we don't want to waste coffee, according to our experience, the effect is better after cleaning the bean grinder.

If you get the results you want, congratulations! But remember, this is just the beginning. Ensuring the accuracy of the data in the test does not guarantee the perfect quality of your coffee, but it is still a shortcut for you to pursue the best quality of your coffee! If you successfully use this method to calculate the formula for one type of coffee, you can start testing the data needed to make other varieties of coffee, such as drip coffee. Then you will know which data are useful and which are not.
