How are coffee beans made into ground coffee? Do they need to be roasted?

Coffee bean production process

Coffee powder is one of the most common drinks in our daily life, but its production process is not simple. Here we will introduce how to make coffee powder from coffee beans.

1. Coffee bean picking and processing

First of all, we have to start with the basics - picking. Only high-quality coffee cherries that have been strictly selected and screened can be used to make high-quality coffee powder. Generally speaking, it is best to choose cherries that are ripe but not rotten or infested by insects.

After picking, these freshly harvested coffee cherries need to be processed. The first step is to remove the outer skin and pulp, usually using mechanical equipment. Then, the remaining part is called the "wet and dry" kernel (what we call "bean").

2. Remove excess material from the kernel

After obtaining the kernel, further cleaning is required to remove possible residues, impurities and other substances that are not conducive to the taste. This step usually includes washing, fermentation or soaking to ensure the purity of the kernel.

3. Roasting of coffee beans

Roasting is an essential step in making coffee powder. During this process, coffee beans are subjected to high temperature treatment, making them easier to grind and extract the coffee aroma. At the same time, different degrees of roasting will also affect the taste and flavor characteristics of the final coffee powder.

Depending on the desired taste and flavor, you can choose to roast the wine to different degrees, such as light roast, medium roast or dark roast. Light roast usually has a more obvious fruity and sour taste; medium roast is more balanced and mellow; while dark roast has a stronger and bitter taste.

4. Grind into powder

After the above steps, we get processed coffee beans with certain flavor characteristics. The next step is to convert them into the fine particles we need to use - that is, coffee powder.

Coffee beans are usually ground using professional coffee grinders. These machines can adjust the coarseness of the powder according to demand to suit the requirements of different brewing methods and equipment.

5. Storage and packaging

The last step is to store and package the freshly made coffee powder. In order to maintain its flavor and quality, packaging materials with good sealing properties and the ability to isolate it from external factors such as oxygen and light are usually selected.

At the same time, during storage, care must be taken to avoid exposure to high temperature, humidity or strong light to prevent quality changes.

Summarize

Through the above steps, we have successfully transformed the original coffee beans into the fragrant and delicious coffee powder that we love and often enjoy. Every link is crucial. Only when each parameter is strictly controlled and attention is paid to details can we obtain high-quality, excellent taste and delicious flavor.
