Can the grinding thickness be universal?

The ideal grinding thickness depends on many factors:

Coffee beans: since coffee has so many flavors, when you buy new coffee beans, you have to adjust the grinding settings to give play to the best flavor of this bean.

Cooking utensils: different cooking utensils may adapt to different grinding thickness. For example, espresso is finely ground, while French filter pots usually use thicker grinding to achieve the best results.

There are many reasons for these differences. The French filter press belongs to soaked coffee, which takes a long time to brew, usually about four minutes, when the thicker grinding slows down the release of the substance. Espresso, on the other hand, is brewed for a short time, usually about 20-30 seconds, and uses pressure to force hot water through the high-density coffee pressed powder, making it suitable for fine grinding.

Baking date: don't forget that coffee is a crop. Coffee, like bread or milk, has its best taste. When the beans are baked, they will begin to decay and lose their flavor. In order to make up for the decline of flavor, the thickness can be adjusted. First of all, you can increase the amount of coffee powder and thicken the grinding a little bit, so that you may be able to give full play to the flavor of coffee beans that have been in place for some time.

Baking degree: different baking degrees affect not only the flavor of the extraction, but also the rate of substance release during extraction. Deep-baked beans will absorb water because of their long baking time and low moisture content, which means that the extraction speed will be accelerated. Generally speaking, coarser grinding for deep baking and finer grinding for shallow baking are recommended.

When you choose the correct grinding configuration, make sure that the grinding thickness matches the way you brew, match the beans you brew, figure out the thickness you think is appropriate, and make sure that the recipe is recorded. Then taste the coffee and record how you feel.

If the coffee doesn't taste as expected, adjust only one parameter on the grinder at a time, and don't move anything else. Of course, some bean grinders have more adjustable settings to make it easier and easier to control when you adjust. But no matter how you adjust, remember exactly what degree of grinding you use to ensure that this practice can be replicated in the future.
