1. Origins –The Genesis of Honey Processing
The honey process finds its roots in Costa Rica, arising as an innovative method to craft delicious coffee while conserving water. In 2008, an earthquake left Costa Rica with extreme water shortages. Coffee producers sought less water-intensive processing alternatives, eventually conceiving what’s now called "honey processing". The pioneering Chacon family of the Las Lajas mill specially engineered machinery allowing exact control over mucilage (i.e., a sticky, sweet layer that surrounds the coffee bean inside the coffee cherry) levels on drying beans. This allowed tailoring the method for exceptional flavors with vastly reduced water usage compared to washed coffees. From Costa Rica, honey processing has now spread in popularity to coffee-growing regions worldwide.
Initially called the “mucilage-drying method,” this technique was later dubbed the “honey process” due to the honey-like sugars that penetrate the drying beans. But let's be clear, despite the name 'honey process', there's no honey involved! From Central America, honey processing has now spread in popularity to coffee-growing regions worldwide. However, it remains far less common globally than washed or natural processing.
2. The Spectrum – Different Types of Honey Processing
Within honey processing lies a spectrum based on how much mucilage remains on the beans during drying. This ranges from "white honey," with minimal mucilage, to "black honey" where nearly all the mucilage stays intact. More mucilage equals longer drying times and bolder, fruitier flavors.
- White Honey: 80-100% mucilage removed after de-pulping. Dries the fastest with clean, subtle flavors resembling washed coffee.
- Yellow Honey: 50-75% mucilage left on. Dries reasonably fast with a slight fruitiness.
- Red Honey: 0-50% mucilage removed. Half the mucilage remains. Slow drying brings out sweetness and fruit.
- Black Honey: Minimal mucilage removal. Nearly all intact. The longest drying elicits deep fruit flavors with rich sweetness and body.
The amount of remaining mucilage on the beans also determines the color they turn during drying. More mucilage equals darker colors from the sticky coating caramelizing on the exterior of the beans.
3. The Process – Depulping, Drying, Milling
While honey processing draws from natural methods, it starts with washed coffee with mechanical de-pulping to remove the fruit skins. The paramount difference is in how much mucilage gets taken off during this first phase. Special honey process depulpers allow exact control over mucilage levels.
1. Depulping Phase: Ripe cherries run through a depulper often with adjustable mucilage removal levels. The amount left on classifies the honey process variation.
2. Drying Phase: Beans dry in the sun or greenhouse with remaining mucilage intact. Meticulous turning is vital to prevent uneven drying or defects. Drying times depend on mucilage levels.
3. Milling Phase: Once dried, the beans go through final milling to remove dried mucilage flakes and the inner parchment layer to reach the green coffee beans.
This method builds sweetness through the sugars in the mucilage penetrating the beans as they dry. But care is critical - too much mucilage boosts risks of over-fermentation or mold formation.
4. The Fermentation – Chemistry Behind the Sweetness
While labels like "honey" may conjure images of bees, the sweetness in these coffees comes from fruit sugars. During drying, natural sugars in the mucilage break down and caramelize onto the beans in a process called fermentation. The sugars chemically transform into sweeter, simpler compounds.
More mucilage means more sugars available to migrate into the beans. But increased fermentation time also allows more sugars to convert to acids. Finding the ideal duration to balance sweetness against acidity levels is key in honey processing and depends on mucilage amounts. Meticulous tuning helps achieve even, controlled fermentation across all beans for optimal flavor consistency. This careful craftsmanship makes properly processed honey coffee rare and prized.
5. Flavor Profile – Fruity, Smooth and Sweet
When optimally honey processed, these coffees shine with indulgent sweetness counterbalanced by crisp acidity. Their flavor profiles tend to highlight ripe fruit notes with heavy, silky bodies.
Compared to natural, honey-processed coffees have cleaner fruitiness with fewer defects. Their fermented fruit sugars also make them sweeter and fuller-bodied than washed coffees.
- White & Yellow Honey: Show subtle fruit with crisp acidity resembling washed coffee.
- Red Honey: Noticeably fruitier with heady sweetness and medium body.
- Black Honey: Deep, fermented fruitiness with a smooth, syrupy body.
Finding the right amount of mucilage removal and drying time means highlighting fruit character while preventing overbearing sugary or sour tones.
6. Roasting – Preserving Sweetness and Fruit
Since optimal flavors develop during primary processing, roasting honey coffee is about preserving inherent qualities in the beans. Light roasts help maintain sweetness and fruit notes. However, adjusting the approach based on mucilage levels can optimize unique attributes:
- White Honey - Roast lighter to keep clean flavors similar to washed coffees.
- Yellow Honey - Low to medium roasts work well to retain mellow fruit tones.
- Red Honey - Medium roasts fully develop the natural sweetness.
- Black Honey - Slightly darker roasts complement the deep fruit notes.
Regardless of roast level, using higher heat like drum roasters followed by fast cooling helps honey-processed beans reach their potential. Gentler roasting better preserves the sugars and fruitiness.
7. Regions – Costa Rica Perfected It, Now Exploring Continues
The birthplace of honey processing, Costa Rica has perfected the craft over decades of honing Methods. Farms here like Beneficio San Vicente and La Pastora produce exceptional honey-processed coffee. The approach has also gained ground in neighboring countries like El Salvador and Guatemala.
But experiments with honey processing now extend to origins worldwide seeking to accentuate inherent fruit character in their beans. Specialty coffee roasters have brought honey methods from Central America to Africa to Hawaii. Innovations continue, like combining honey processing with other techniques such as anaerobic fermentation for intensely fruit-forward micro lots.
As the specialty coffee scene evolves, interest in honey coffee rises. These indulgently sweet yet nuanced coffees attract enthusiasts craving an engaging “third wave” experience beyond traditional processing.
8. Sustainability – An Eco-Friendly Innovation
The origins of honey processing stemmed from seeking an environmentally friendly alternative to washed methods requiring copious water usage. Honey-processed beans dry intact with sugars from the fruit penetrating the seeds. This means no water gets used to wash away mucilage like wet processing.
By reducing water requirements, the honey process allows coffee mills in arid climates or during droughts to conserve water while still crafting specialty-grade beans. In an increasingly warm, parched world, this sustainable innovation may prove vital for exceptional coffee.
9. Enjoying Honey Processed Coffees
If you wish to dive into the nectar-like world of honey-processed coffee, sampling different types can reveal preferences for depth of sweetness and fruit character. Be sure to try lighter roasted coffees to allow their qualities to sparkle. Here are some tasting tips:
- White Honey – Best resembles washed coffee with delicate fruit, good for black coffee.

Honey Procees FAQ
What is a honey-processed coffee?
Honey-processed coffee is a method of processing coffee beans where some of the fruit mucilage is left on the beans during the drying process. The mucilage is the sticky, sweet layer on the inside of the coffee cherry fruit surrounding the bean. Leaving some of this layer intact allows its sugars to seep into the bean, giving honey-processed coffee a sweeter, richer flavor.
Does honey-processed coffee contain sugar?
No, there is no actual sugar added during honey processing. The sweet flavor comes from the fruit sugars in the mucilage penetrating the bean as it dries. More mucilage left on means more inherent sugars get absorbed to make a sweeter cup of coffee with no additional sugars needed.
Is honey-processed coffee sweeter?
Yes, honey-processed coffee tends to taste sweeter than other processing methods like washed or natural. The fruit sugars absorbed into the bean during drying impart a natural sweetness and syrupy mouthfeel. Coffees with more mucilage left on end up sweeter while those with more mucilage removed have more subtle sweetness.
Is honey-processed coffee vegan?
Yes, honey-processed coffee would be considered vegan. No animal products are used anywhere during honey processing. It simply involves leaving some of the coffee fruit mucilage on the bean as it dries. So while the name may sound misleading, there is no actual honey involved. Just sweet flavors from the fruit sugars in the mucilage penetrate the drying beans.
