Coffee bean grinding: the basics

Coffee is one of the most popular beverages in the world, and grinding coffee beans is an important part of determining the taste and flavor of coffee. In this article, we will delve into the basic knowledge about coffee bean grinding.

Why do you need to grind coffee beans?

First, let's understand why we need to grind coffee beans. Simply put, by grinding the whole coffee beans into powder form, we can increase the contact area with water and release more aroma and taste. In addition, during the brewing process, different coarseness of coffee powder will affect the water flow rate, thereby affecting the extraction process.

Choosing the right coffee machine

Before we start talking about specific grinding methods, make sure you have a suitable home or commercial electric or manual blade or sharp edge model to choose from for better grinding of coffee beans.

Choice of thickness

The coarseness of coffee beans is one of the important factors affecting the taste and flavor of coffee. Different brewing methods require coffee powder of different coarseness. Generally, the more common and widely used ones are the following: extra fine, medium, medium-fine, coarse and very coarse.

Brewing method and grinding degree

For different brewing methods, we need to choose the appropriate level to achieve the best effect and taste and flavor adjustment required for the method. For example, if you like to use a French press to make a rich and full taste with a strong aroma and certain flavor types as the dominant component type, you can choose a relatively medium or slightly medium-fine level for processing; and if you want to make a fresh and refreshing coffee with bright acidic characteristics and a certain sweet aroma, you can try to be closer to the state of trembling at a very small vibration frequency, that is, a very fine level.

Preparation before grinding

Before you start grinding coffee beans, some preparations are necessary. First, make sure your coffee machine is clean and free of residue. Second, measure the appropriate amount of coffee beans as needed and put them into the grinder. Finally, before you start, check that the blade or sharp edge is sharp and adjust the coarseness setting as needed.

How to Grind Coffee Machine Correctly

When all the preparations are done, we can start using the coffee machine to crush the beans. Turn on the power and press the start button to enter the operating state, then slowly rotate upwards to adjust the coarseness to achieve the desired effect and taste. At the same time, be careful not to shake or vibrate too quickly to avoid excessive static electricity, which will affect the taste.

Storing crushed coffee

Finally, before pouring out the ground coffee, make sure to choose a suitable and tight container to store it to avoid being affected by air, humidity, light, etc. It is best to keep the ground coffee fresh before use and avoid long-term exposure to the outside environment.

in conclusion

Grinding coffee beans is an important step in determining the taste and flavor of coffee. By choosing the right machine, adjusting the coarseness, and operating and storing it correctly, we can make delicious coffee that suits our personal taste preferences. I hope this article will help you understand the basic knowledge about coffee bean grinding.
