What method of processing coffee includes fermenting the beans?

The wet process, also known as the washed process, involves fermenting the coffee cherries to separate the beans from the fruit. In this method, harvested cherries are first pulped to remove the outer skin, and then the beans, still covered in mucilage, are fermented in water tanks. This fermentation helps break down the mucilage, allowing for easier washing and extraction of the beans. The beans are then thoroughly rinsed and dried.

This process can enhance the coffee's flavor profile by highlighting its acidity and sweetness, resulting in a cleaner and more vibrant cup of coffee. The careful control of the fermentation phase is crucial, as it affects the final taste and quality of the coffee. Each step in the wet process contributes to these flavor characteristics, making it a distinct and important method of coffee processing.
