The acidity, sweetness, mouthfeel, and aroma of a cup of coffee are intimately related to the processing method. With the recent popularity and prevalence of specialty coffee, many academics have delved into fields such as fermentation and honey processing. Many estates around the world have developed their unique insights and specialized techniques for processing coffee beans, demonstrating the importance of processing methods.

What is Honey Processing?

Honey processing is a method that falls between washed and natural processing, also known as semi-washed processing.

Step-by-Step Honey Processing

Step 1: Initial Cleaning

The first step in all processing methods involves simple screening to remove floating beans and cleaning the surface. Honey processing requires particularly thorough completion of this step. Similar to natural processing, there's a higher risk of mold and contamination. If each stage can be precisely controlled, the proportion of defective beans can be effectively reduced. Repeated agitation of coffee beans ensures more thorough removal of all defective and damaged coffee cherries, followed by removal of external coffee pulp and skin.

Step 2: Mucilage Preservation

The second step involves placing the screened coffee cherries into a depulper, preserving the mucilage as completely as possible. This is where honey processing reveals its most distinctive characteristic: the degree of honey processing is determined by how much mucilage layer is retained (white honey, yellow honey, red honey, black honey). More mucilage to less mucilage equals black honey to white honey. The mucilage layer is rich in sweetness and flavor, determining the tone and mouthfeel of this batch of honey-processed coffee.

Step 3: Drying Process

The coffee beans, now with their determined honey processing level, are placed in a dry area with minimal vegetation for sun exposure. Because the sweet, aromatic mucilage easily attracts animals and insects to linger and feed, the beans need to be stirred several times daily to check their condition and reduce the possibility of contamination. The drying time depends on the thickness of the mucilage layer, with the primary criterion being moisture content below 11%.

Step 4: Final Processing

The length of sun exposure time is determined by the thickness of the mucilage layer. The final criterion is coffee bean moisture content below 12%, after which storage can begin. Remember to remove any leaves and foreign materials mixed in during the drying period to prevent spoilage during storage. This oversight could potentially ruin the entire batch of coffee beans.

Advantages of Honey Processing

As a processing method between washed and natural beans, honey processing offers a harmonious blend of effects. The cleanliness, acidity, and sweetness of the coffee are determined by the honey processing level. Honey processing often imparts coffee beans with a subtle honey aroma and strong fruity acidity, while still maintaining the coffee's rich body.

Disadvantages of Honey Processing

This processing method requires extremely precise process management to ensure that the entire batch of coffee beans receives the same level of honey processing, thereby guaranteeing coffee consistency. To maintain the defect rate expected of specialty coffee beans, honey processing is often more costly than washed processing.
