The roasting journey of coffee beans: from origin to aromatic taste, do you know the process?

The roasting process of coffee beans is a process of heating and processing the raw coffee beans to achieve the best taste and flavor. This process starts from the origin and goes through many steps to finally become the fragrant coffee we love.

First of all, the origin of coffee beans is usually in Asia, Africa or Latin America. These places have suitable climate and soil conditions, allowing coffee trees to thrive. When the fruits are ripe, farmers will pick them by hand and perform preliminary processing.

Next, shortly after picking, farmers will peel and pulp the coffee cherries. This step is called "wet processing", which removes the remaining mucus in the pulp and retains the seeds inside, namely the coffee beans.

Then, after wet processing, the remaining beans with a high moisture content and an outer layer of detached matter (called "sticky face") need to be dried further. This step is called "dry processing", and farmers will spread the coffee beans out in the sun or use special mechanical equipment to dry them to reduce the moisture content.

After the drying process, the coffee beans are graded and sorted. Farmers sort the beans based on factors such as size, shape, and quality. This helps ensure that the beans in each batch have similar characteristics and allows for better control of uniformity during the roasting process.

The last step is the most critical and anticipated step - roasting. In professional coffee shops or manufacturers, experienced masters will determine the appropriate roasting degree according to different types and flavor requirements. By heating the coffee beans, a chemical reaction occurs inside them at high temperature, releasing aroma and flavor substances.

The whole process requires mastering multiple factors such as time and temperature, and different types and origins of coffee require different levels of processing to achieve the desired effect. From origin to aromatic taste, the roasting journey of coffee beans is a process full of skills and art.

In short, the roasting process of coffee beans starts from the origin, goes through picking, wet processing, dry processing, grading and classification, and finally achieves the best taste and flavor through roasting. This process requires the joint efforts of farmers, masters and professional equipment to transform coffee beans into the mellow coffee we love.
