Coffee bean process: a perfect journey from origin to roasting

Coffee is one of the most popular drinks in the world, and coffee beans are the key to making delicious coffee. In order to ensure that every cup of coffee can achieve the best taste and flavor, it needs to go through multiple processes from origin to roasting. This article will take you to learn more about this perfect journey.

1. Harvesting and processing at the origin

High-quality coffee beans first need to grow in suitable climatic conditions. The main growing areas include Brazil, Colombia, Vietnam and other countries. When the fruits are ripe, farmers will pick them by hand and perform preliminary processing.

The process usually involves removing the skin and pulp, leaving the seeds inside, known as the "coffee bean." The seeds are then fermented in water to remove residual matter, and washed and dried to reduce the water content.

2. Grading and classification

After initial processing, the coffee beans are graded and sorted according to size, shape and quality. This process is designed to ensure the consistent quality of each batch of beans and provide a basis for subsequent processing and roasting.

Grading and sorting are usually done by visual inspection or mechanical screening. Larger, more regular beans are considered high-quality, while smaller or irregularly shaped beans are classified as inferior.

3. Transportation and storage

Once the coffee beans are graded and sorted, they are shipped to coffee producers around the world. During transportation, maintaining the proper temperature and humidity is very important to keep the coffee beans fresh.

After arriving at the destination, the coffee beans will be temporarily stored in specially designed warehouses. These warehouses usually have controlled temperature, humidity and air circulation to ensure the best preservation condition.

4. Pre-baking treatment

Before entering the next stage, roasting, the coffee beans need to undergo some further processing. This includes removing the outer protective membrane, as well as washing and sorting the beans.

The process of removing the protective membrane is called hulling, and it can be done mechanically or hydraulically. The beans are then washed and screened again to ensure the surface is clean and free of impurities.

5. Baking

Roasting is one of the most important steps in the entire process. During the roasting process, coffee beans are exposed to high temperatures and gradually undergo chemical changes.

Different types of coffee require different degrees of roasting to bring out their unique flavors and aromas. Light roasting usually produces light, acidic coffee with floral and fruity aromas, while dark roasting makes the coffee more bitter, rich in taste, and with chocolate or nutty flavors.

6. Cooling and packaging

Once the beans have reached their ideal state, they are immediately cooled to stop the roasting process. This helps preserve the flavor and aroma of the beans.

Finally, the beans are packaged, usually in sealed bags or jars to prevent oxidation and moisture from seeping in. This ensures that the beans remain fresh during transport and storage.

Conclusion

The perfect journey from origin to roasting ensures that every cup of coffee can achieve the best taste and flavor. Through careful picking, processing, grading and classification, transportation and storage, pre-roasting and roasting processes, high-quality coffee beans can become the delicious cup of fragrant coffee we drink.
