In the world of coffee, processing refers to the set of processes that transform the fruit of the coffee tree, known as a cherry, into the green coffee bean that will later be roasted. This term is also used to name the place or infrastructure where this process is carried out.
Processing begins right after harvesting and is one of the most important stages in the coffee chain, as it largely defines the flavor, aroma, and final quality of the beverage.
Stages of Coffee Processing
Although it can vary depending on the method used, processing usually includes the following phases:
-
Pulping: the pulp is removed from the cherry to extract the bean.
-
Fermentation: a controlled process that helps eliminate mucilage and develop sensory profiles.
-
Washing: cleaning the bean after fermentation (in washed methods).
-
Drying: reducing the moisture of the bean to an optimal level for storage.
Importance of Processing
Good processing can enhance the best qualities of coffee, while a poorly executed process can introduce irreversible defects. For this reason, processing is considered an art and a science within coffee cultivation.
