Coffee bean processing technology: from picking to roasting, the whole process of analyzing the exquisite transformation of coffee

pick

The coffee bean processing begins at the picking stage. At this stage, farmers carefully select coffee cherries that are at the right maturity for picking. Generally speaking, the best time to harvest is when the coffee cherries are fully red. This ensures that the beans are fully developed and have the best flavor characteristics.

Peeling and fermentation

Once the coffee cherries are picked, the outer skin needs to be removed. This is usually done mechanically or by hand. The remaining pulp and mucilage are then retained and fermented in a closed container.

Washing and rinsing

After a certain period of fermentation, the beans are washed and rinsed in water. This step is to remove residues and further improve the quality of the beans. Farmers usually use clean water or running water to repeatedly rinse the beans until they are completely clean.

Drying

After washing, the beans need to be dried. This process involves laying the beans out in the sun, allowing them to gradually lose moisture and become dry. The time and method of drying will vary depending on local climate conditions, but it usually takes several days or weeks.

Sorting and storage

Once the beans are completely dry, they are sorted and stored. This step is designed to group the beans according to characteristics such as size, shape and quality, and ensure that they remain in the best condition. Farmers usually use sieves or other tools to sort the beans and put them into appropriate containers.

Baking

The last key link is the roasting process of coffee beans. This step can be said to be the most important part of the entire processing process, because it directly affects the formation and development of coffee flavor. During the roasting process, farmers will control parameters such as temperature and time based on their understanding of flavor characteristics and market demand, and adjust the firepower to make the coffee beans reach the ideal roasting degree.

Summarize

From picking to roasting, coffee beans go through a series of delicate processing steps. Each step has an important impact on the final coffee quality. By properly controlling and adjusting these steps, farmers can transform ordinary coffee berries into high-quality coffee with rich aroma and taste.
