Natural coffee bean processing: the art of roasting, the magic of the sun!

There is an art to roasting coffee beans, and one of the most popular methods is natural roasting, which uses the magic of sunlight to impart a unique flavor and taste to the coffee beans.

First, the sun drying method requires freshly picked coffee cherries to be spread out on large open fields for drying. This process can take several days or even weeks, depending on local climate conditions. While being exposed to the sun, farmers will constantly stir and turn the coffee cherries to ensure that they dry evenly.

Through the sun treatment, the moisture inside the coffee beans gradually escapes, and the surface becomes hard and dry. Many chemical reactions occur in this process, including oxidation, caramelization, and dehydration. It is these reactions that give the coffee beans their special aroma and flavor.

Compared with other processing methods, drying in the sun allows the coffee beans to absorb the sun's energy more evenly and helps increase the sweetness and acidity of the coffee beans. In addition, the sun-drying method can also reduce the bitterness and impurities of the coffee beans, making the taste smoother.

However, the solar drying method also has some limitations. First, it has high requirements for climatic conditions. Solar drying can only be effectively carried out in areas with sufficient sunlight, suitable temperatures and low humidity. Secondly, the coffee cherries need to be constantly stirred and turned during the drying process, which is a time-consuming and labor-intensive task for farmers.

Overall, the natural drying of coffee beans is a unique and ancient method that is still widely used around the world. By utilizing the natural drying method under the sun, this method gives the coffee beans an unparalleled flavor and aroma, and has become one of the reasons why many people love it.
