Honey Process

The honey process was developed in Costa Rica in the early 2000s as an evolution of the pulped natural process. Costa Rican producers, seeking to differentiate their coffees, refined the technique of leaving varying amounts of mucilage on the bean during drying. The process gained international recognition when Costa Rican honey-processed coffees began winning competitions. The name 'honey' refers to the sticky mucilage left on the bean, not to honey flavor. The process has since spread to other Central American countries and beyond.

The honey process is a hybrid: the cherry skin is removed (like washed), but the mucilage is not fully washed off (like natural). The remaining mucilage ferments and dries on the bean, infusing sugars and acids into the seed. The amount of mucilage left determines the cup profile: white honey (least mucilage, most washed-like), yellow honey, red honey, and black honey (most mucilage, most natural-like). The fermentation during drying is less intense than in natural process because there is less fruit material, but more than in washed process. The sugars in the mucilage caramelize during drying, contributing sweetness and body.

1. Harvesting: Ripe cherries are selectively picked. 2. Sorting: Cherries are sorted by ripeness, often using flotation. 3. Depulping: The outer skin is mechanically removed, but the mucilage is left on (using a depulper calibrated to remove only the skin). 4. Mucilage control: The amount of mucilage left can be adjusted using a mechanical demucilager or by choosing not to ferment/wash. 5. Drying: The mucilage-covered beans are dried on raised beds or patios. The mucilage ferments and dries simultaneously. 6. Raking: Beans are raked regularly to ensure even drying and prevent mold. 7. Covering: Beans are covered during rain and at night. 8. Moisture monitoring: Drying continues until beans reach 10-12% moisture (7-20 days depending on honey type). 9. Hulling: The dried parchment with honey coating is hulled. 10. Sorting and Grading: Green coffee is sorted by size, density, and defects.

Fermentation in the honey process occurs during drying, not in a separate tank. The mucilage left on the bean contains sugars and pectin that ferment as the bean dries. The fermentation is milder than in natural process because there is less fruit material. The amount of mucilage left determines the fermentation intensity: white honey has minimal mucilage and fermentation; black honey has maximum mucilage and fermentation. The fermentation produces acids and alcohols that contribute to the cup's complexity. The mucilage also caramelizes during drying, contributing sweetness and body. The risk of over-fermentation is present but lower than in natural process.

Drying in the honey process is critical and takes 7-20 days depending on the honey type. White and yellow honey dry faster (7-12 days) because less mucilage means less moisture to remove. Red and black honey dry slower (12-20 days) because more mucilage retains more moisture and requires more careful management. Beans must be raked regularly to prevent mold and ensure even drying. The drying environment affects the final color and flavor: faster, sunnier drying produces lighter colors; slower, shaded drying produces darker colors. Raised African beds are preferred for better airflow.

Honey-processed parchment can be stored in breathable bags in cool, dry conditions for 30-60 days. After hulling, green coffee is stored in GrainPro or hermetic bags. The higher sugar content of honey-processed coffees makes them somewhat more sensitive to storage conditions than washed coffees. Store at 15-25 C with 50-60% relative humidity.

• •Combines clarity of washed with body and sweetness of natural
• •Unique, complex flavor profile prized in specialty coffee
• •Lower water usage than washed process
• •Less risk of defects than natural process
• •Can produce exceptional competition-winning coffees
• •Allows producers to differentiate their product

• •Requires precise control of mucilage amount and drying
• •Labor-intensive drying process (frequent raking required)
• •Vulnerable to weather during drying
• •Inconsistent results if not managed carefully
• •Higher risk of mold than washed process
• •Requires skill and experience to execute well

Honey-processed coffees are characterized by medium-to-high sweetness, medium body, and moderate acidity. They combine the clarity of washed coffee with the sweetness and body of natural. The flavor profile varies with honey type: white honey is clean and bright (similar to washed); yellow honey has mild sweetness and body; red honey has pronounced sweetness, fruit notes, and body; black honey is the closest to natural, with intense sweetness, body, and fruit notes. Honey coffees often have caramel, honey, and brown sugar notes. They retain more of the coffee's inherent character than natural process.

• •Over-fermentation from slow drying or excessive mucilage
• •Mold from inadequate raking or covering
• •Uneven drying causing inconsistent cup quality
• •Inconsistent mucilage removal causing flavor variation
• •Fermented or rotten flavors from over-fermentation

The honey process uses significantly less water than the washed process because the mucilage is not washed off. This makes it environmentally favorable in terms of water usage. However, it still requires some water for depulping. The drying process requires significant land area for raised beds or patios. No significant wastewater is produced. The process is generally considered more environmentally friendly than washed but less so than natural.

• •Color-controlled honey processing (precise mucilage measurement for consistent white/yellow/red/black honey)
• •Anaerobic honey fermentation (mucilage-covered beans fermented in sealed bags before drying)
• •Yeast-inoculated honey processing for controlled fermentation
• •Controlled-environment drying (greenhouses, solar dryers) for weather independence
• •Mechanical demucilagers calibrated for precise mucilage control
