Coffee bean process: from picking to roasting, a journey to enjoy the aroma of coffee

Coffee is one of the most popular drinks in the world, and making a cup of delicious coffee requires a delicate and complex process. From picking to roasting, each step has an important impact on the final taste. This article will take you through this fascinating process.

1. Picking

Coffee beans are the seeds picked from coffee trees. Usually, only the fruits that have reached a certain level of maturity are selected for picking. This ensures that the beans contain enough sweetness and flavor substances.

In most areas, manual harvesting is the preferred method. Farmers peel the ripe fruits by hand or with special tools and collect them in baskets.

Although manual picking is time-consuming and laborious, it ensures that only beans of the best quality and appropriate maturity are selected, thus laying the foundation for the quality of the coffee.

2. Peeling and fermentation

Once picked, the beans go through a process called peeling and fermentation, which separates the pulp from the seeds and helps remove the mucilage on the surface of the seeds.

First, the picked fruits are washed in a tank, and then in a special device, a machine crushes the fruits vigorously to separate the seeds inside.

Next, the seeds are placed in a fermentation tank for a period of time. During this process, bacteria and natural enzymes break down the mucilage and change the internal structure of the beans. This step has an important impact on the taste and flavor of the coffee.

3. Wash or dry

After fermentation, the coffee beans can be processed either by washing or drying.

The washed method is to soak the beans that have been demucined in clean water again for washing. This can further remove the remaining pulp and other impurities. The washed method usually makes the coffee beans have a brighter and fresher taste.

The drying method is to place the beans in the sun or special equipment for natural or artificial drying. This method can retain more natural flavors, but it is also easily affected by climatic conditions.

4. Baking

Roasting is the most important step in making coffee, as it determines the final taste and flavor characteristics of the coffee beans.

During the roasting process, the raw beans are heated to a high temperature and kept heated for a period of time. As the temperature rises, the beans, which originally contain moisture and acidic substances, begin to undergo chemical reactions, producing aroma and color changes.

Different degrees of roasting will produce different types of coffee: light roasts are usually acidic, floral and fruity; medium to dark roasts are richer, bitter and have chocolate or nutty flavors.

5. Grinding and Brewing

Finally, the roasted coffee beans need to be ground and used to brew a delicious cup of coffee.

Grinding beans is selected according to different brewing methods and personal taste preferences. The fineness, coarseness and uniformity will affect the final coffee taste.

Then, soak or filter the ground coffee powder with an appropriate amount of water to get a cup of fragrant and delicious coffee.

Conclusion

From picking to roasting, each link has an important impact on the final quality. Only high-quality coffee beans that have been carefully selected, processed and produced can bring us a rich and intoxicating taste experience. Let us cherish the efforts behind it when tasting each cup of fragrant coffee.
