Coffee bean processing technology: from picking to roasting, perfect presentation of mellow taste

Picking coffee beans

The quality of coffee depends on many factors, the most important of which is the picking of coffee beans. Generally speaking, coffee berries with moderate maturity will produce the best taste and aroma. Therefore, during the picking process, farmers need to carefully choose the right time.

To ensure that each bean is in perfect condition, workers usually hand-pick each fruit. Although this method is time-consuming and laborious, it ensures that only the best quality fruits are collected.

Processing and peeling

Once the coffee beans are picked, they need to be processed and peeled. They are first soaked in water to ferment. This process helps remove the pulp and also increases the activity of enzymes inside the beans.

Later, after washing away any residue, the peeling can take place. This is usually done mechanically, where special equipment is used to peel away the outer cellulose material.

Fermentation and cleaning

After the husks are removed, the coffee beans need to be fermented, a process that places the beans in a specific environment so that they can further develop their unique flavor and aroma.

After fermentation is complete, the beans need to be thoroughly washed. This step is very important because any residue may negatively affect the final taste.

Drying and sorting

The washed coffee beans need to be dried in the sun. This process helps remove moisture and further enhances the flavor.

At the same time, before drying, workers will sort the coffee beans and divide them into different grades according to factors such as size, shape and color.

Baking

The last key step is roasting the coffee beans. By controlling parameters such as temperature and time, each bean can reach the ideal state.

Brief heating at high temperatures evaporates the internal water and produces aroma compounds. Over time, the beans darken in color and become more flavorful.

Summarize

The processing of coffee beans is a complex and delicate process. From picking to roasting, each step has an important impact on the final taste and aroma. Only by carefully controlling each link and using high-quality raw materials can the mellow taste of coffee beans be perfectly presented.
