FrontStreet Coffee - Introduction to Honey Processing Method

Honey Processing Method:

What is honey processing? According to its original English meaning, the scientific term should be "pulp natural." Similar to the traditional wet processing method, it removes the thick skin of the coffee cherry while retaining the sticky mucilage layer underneath. Unlike wet processing, it doesn't use fermentation to remove the mucilage layer; instead, it allows the coffee beans to dry with this layer intact, after which the mucilage and parchment are removed directly.

Challenges of Honey Processing:

1. During the drying process, because the mucilage layer remains on the coffee beans, they must be turned frequently in the first few days to prevent the beans from clumping together. Therefore, it requires more manual labor than the typical washed method.

2. If the beans cannot be dried quickly, they are prone to over-fermentation.

3. If turning is insufficient, or if the overall environment is too humid or cold, or if the mucilage layer is left too thick, the coffee beans can easily mold. For this reason, some coffee estates use machines to control the thickness of the retained mucilage layer, allowing the coffee beans to dry faster and achieving better consistency in overall flavor profile.

4. Compared to wet processing, honey processing requires more space and takes longer to dry.

Enhancement Methods:

1. During the first 2-3 days of sun drying, it's best to complete this process under constant monitoring. During this period, part of the mucilage layer has already dried, and the coffee is less likely to develop undesirable fermentation flavors.

2. During the drying process, elevated racks can be used to improve ventilation throughout the process, making it less prone to mold growth.

3. If drying in a courtyard or terrace, the mucilage from the pulp layer will seep into the courtyard, so it must be thoroughly cleaned before drying the next batch of coffee beans.

Flavor Characteristics:

The advantage of honey processing lies in enhancing the body and sweetness of coffee (hence the English term "honey process" or "miel process"), while relatively reducing its acidity. The aroma tends to be more delicate. However, this is the flavor profile when honey processing is executed perfectly. If poorly executed, it will have unpleasant vinegar-like flavors, spicy notes similar to onions or garlic. Even when executed quite well, it may still carry some earthy notes, the aftertaste may be less clean, and off-flavors will be more pronounced than in typical washed processing. Therefore, overall, honey processing carries significantly higher risks than standard wet processing.

Knowledge Expansion:

The main origins of Arabica coffee beans include South America, Central America, Africa, and Asia. China's Yunnan, Hainan, and Taiwan regions also cultivate small amounts of Arabica coffee beans.
