The Science of Coffee Processing
How are coffee beans processed once they have been harvested? It is essential for determining their final flavor.
Washed (Wet) Processing
Washed processing removes the fruit before drying, producing clean and bright coffee flavors. This method enhances the beans’ inherent qualities by fermenting and soaking them to remove the mucilage. The result is a coffee with a more pronounced acidity and clarity, often preferred by specialty coffee producers.
Natural (Dry) Processing
When beans are dried with the intact fruit, natural processing results in fruity and complex coffee profiles. This method allows the sugars from the fruit to infuse into the beans, creating a sweeter and more robust flavor. Natural processed coffees often exhibit berry-like and winey notes, making them a favorite for those who enjoy bold and fruity coffees.
Honey Processing
Honey processing combines washed and natural processing to produce diverse and distinctive flavors. The beans are partially washed, leaving some mucilage on during drying, which enhances sweetness and complexity. This method produces a coffee with a balanced profile, offering the best of both washed and natural processes.
The Influence of Altitude and Climate
The altitude and climate of a coffee-growing region significantly impact the development and flavor of coffee beans.
High-Altitude Coffee
Due to the slower maturation process in cooler temperatures, high-altitude coffee farms produce beans with enhanced acidity and intricate flavors. These beans develop more complex sugars, creating a refined taste profile with bright acidity and floral or fruity notes. Regions like Ethiopia, Kenya, and Colombia are known for their high-altitude coffee production.
Low-Altitude Coffee
Coffee cultivated at lower elevations often possesses a richer body and less pronounced acidity, resulting in a distinct flavor profile.
