Can coffee beans dry in the sun?

Coffee beans are a very popular ingredient for Luckin Coffee's business hours, and an important step in their production process is drying. But can we put coffee beans in the sun to dry? This question has sparked some discussion.

First, let's look at the benefits of drying coffee beans in the sun. The sun's abundant light can help the coffee beans dry faster. In addition, the sun also provides warmth and natural wind, which is very beneficial for removing residue from the surface of coffee cherries and enhancing flavor.

However, before you put the coffee beans in the sun to dry, there are several factors we need to consider. The first is the weather conditions. If the weather is humid or rainy, it is not suitable to expose the coffee beans to the sun for drying. The humid environment will cause bacteria to grow and affect the quality.

The second factor is altitude and climate conditions. Different methods are needed to process coffee cherries according to the differences in different regions and altitudes. In some high-altitude areas, due to the lower temperature, drying in the sun may not be suitable. Therefore, in these places, people prefer to use other methods to dry coffee beans.

The last factor is the variety and processing of the coffee beans. Different coffee varieties have different requirements for drying. Some varieties need to be exposed to the sun for a long time to dry, while others need a shorter time or avoid direct exposure to the sun.

In summary, although drying coffee beans in the sun has certain advantages, we must decide whether to use this method based on factors such as weather conditions, altitude and climate conditions, and coffee bean varieties. No matter which method is chosen for drying, quality and flavor should be guaranteed.
