The whole process of coffee beans: from picking to roasting, learn about the birth of a cup of fragrant coffee

The process of picking coffee beans

The birth of coffee beans begins with them being carefully picked. In the plantation, when the berries on the coffee trees are ripe, farmers will peel them off by hand or with tools. This process requires care and patience to ensure that only ripe berries are picked.

Processing and peeling

Once the coffee beans are picked, they go through a series of processing steps. The first is peeling. Farmers usually use a machine or manual methods to peel off the outer layer of the fruit. This step ensures that only the coffee beans inside are retained.

Fermentation and cleaning

Next, the peeled coffee beans are fermented and washed. This step is very important because it helps remove the pulp that remains on the surface of the beans and adds taste and flavor characteristics. During the fermentation period, the coffee beans are placed in water for a period of time and stirred regularly. Then, they are rinsed to remove any residue.

Drying and sorting

After washing, the beans need to be dried. Farmers usually spread them out in the sun or use special machines to speed up the drying process. This step ensures that the moisture content of the beans is reduced to the appropriate level and prevents mold growth.

Once the coffee beans are completely dried, they are sorted and graded. The beans are separated into different grades based on factors such as size, shape, and quality. This helps determine the quality and value of the final product.

Baking process

After the previous processing steps, the coffee beans are ready for roasting, which is one of the most important steps required to produce a rich and delicious coffee.

Before roasting begins, a selected amount of green beans is placed in a device designed specifically for processing grain products (including cereals, nuts, etc.); the device has a temperature-controlled heater that heats the coffee beans to the appropriate temperature within a set time. During this process, the coffee beans undergo chemical changes, releasing a pleasant aroma.

As time goes by and the temperature rises, the coffee beans begin to change color. First, they change from light yellow to light brown, and then gradually become dark brown or dark brown. Different degrees of roasting will produce different flavor characteristics and tastes.

Cooling and packaging

Once the desired color and taste are achieved, roasters stop heating the beans and quickly cool them to prevent further heat exposure. This helps preserve the best flavor.

The last step is to package the processed and roasted coffee beans. They are usually packed in sealed bags to keep them fresh and marked with information such as origin, variety, and yield.

Conclusion

From picking to roasting, every step plays a vital role in the final cup of mellow coffee. Only coffee beans that have been carefully processed and roasted can release the most delicious flavor and aroma.

Now you can appreciate the complex process behind a cup of coffee and better savor the satisfaction that comes with every sip.
