The scale is just a reference, different brands have different grinding scales, and the performance of the same model bean grinder of the same brand under the same scale is not exactly the same. it is better to understand it this way: the scale just tells you which direction is thick and which is fine. when you find a suitable powder thickness, the role of the scale will show a little bit. The premise is that only your bean grinder, and can not change the beans, the amount of powder remains the same, the strength of the powder can not be changed.

The brand of the mill is different, and the thickness of the powder from the same scale identified by each brand is different, which can only be adjusted from your cooking method. At the same cooking temperature, the powder is thicker, the extraction time can be longer, the powder is finer, and the extraction time can be shorter. Basically, regardless of the variety, siphon and hand-made coffee powder the size of granulated sugar is more suitable.

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.

How to adjust the bean grinder?

The adjustment methods of different types of bean grinders are different. First of all, you need to have an in-depth understanding of the structure of the bean grinder and the method of adjusting the parameters. Do not adjust the parameters more than 3 mm at a time. If you often adjust the parameters of the bean grinder, then each adjustment should not be too large. When the steps of weight, flattening and pressing are the same, the adjustment of 3mm is enough to allow the extraction time of coffee to fluctuate up and down for 3-5 seconds.
