What Is Honey Process Coffee and How Is It Done?

Ever wondered how your coffee beans go from a cherry on a tree to the bold, nuanced cup in your hand? Most coffee lovers focus on roast levels or origin stories—but the way coffee is processed after harvest plays an even bigger role in shaping its flavor. One lesser-known but increasingly important method is the honey process, especially popular in Central America.

Honey process, or miel process, removes the coffee cherry’s skin and pulp but leaves some or all of the sticky mucilage—hence the “honey” name—while drying the beans. It sits between washed and natural processes in terms of flavor complexity and water usage.

The Anatomy of a Coffee Cherry

Coffee cherries have five distinct layers. Starting from the outside:

• Skin/Pulp: The outer fruit layer, similar to a cherry’s skin, always removed immediately after harvest. Also called “pulp,” used in some regions to make tea.
• Mucilage ("Honey"): A thick, sugary, and extremely sticky layer beneath the pulp. This layer is key to the honey process, rich in sugars that influence sweetness during drying.
• Parchment: A tough, cellulose layer protecting the bean, resembling parchment paper once dried.
• Silver Skin/Chaff: A thin, silvery inner layer that flakes off during roasting.
• Coffee Bean: Each cherry typically holds two beans, except for the rare peaberry, which has just one.

Three Main Coffee Processing Methods

Coffee is processed using one of three primary methods, distinguished by how many layers are removed before drying:

What Is the Honey Process?

The honey process is primarily used in Costa Rica, and has spread across Central America. After harvesting, coffee cherries are depulped to remove the skin and pulp, but a portion—or all—of the mucilage is left intact. The beans are then dried on patios or raised beds without washing away the sticky layer.

This partial retention of mucilage gives the process its name, as the sticky substance resembles honey. Unlike natural processing, there’s minimal fermentation. The result is a coffee that’s sweeter than a washed process bean, with more body and less acidity than a natural. The level of mucilage left on the bean determines the characteristics of the final cup—and also gives rise to different “honey” grades.

Honey Process Grades: 40%, 60%, 80%, 100%

Honey process coffees are categorized by how much mucilage is left on the bean after pulping. Though originally determined by how much mucilage stuck during transport or washing, today farmers deliberately control the amount retained:

• 40% Honey: Least mucilage left; faster drying, milder flavor.
• 60% Honey: Moderate mucilage; balanced sweetness and acidity.
• 80% Honey: More mucilage retained; richer body and sweetness.
• 100% Honey (Black Honey): All mucilage remains; longest drying time, most complex and sweet profile.

Farmers may choose to leave more or less mucilage based on climate control, desired cup profile, and risk of over-fermentation.

Honey Process Color Grades: Yellow, Red, Black

In Costa Rica, honey process coffees are also graded by the color of the dried bean, which reflects how long and under what conditions they were dried:

• Yellow Honey: Dried fastest (about a week) with maximum sun exposure and frequent turning. Lighter body, cleaner flavor.
• Red Honey: Dried slower (2–3 weeks), often in partial shade. More sweetness and complexity.
• Black Honey: Dried the slowest (at least 2 weeks) in minimal light and shade. Richest, sweetest, and most labor-intensive. Often the most expensive.

The longer drying times reduce mold risk but require careful management. Black honey coffees tend to mirror natural process intensity with the cleanliness of washed coffees.

How Honey Process Compares

Honey process sits in a flavorful middle ground:

• Compared to washed coffee, it’s sweeter and fuller-bodied, with lower acidity.
• Compared to natural process, it has cleaner flavors, less fermentation risk, and more controlled sweetness.
• It uses less water than washed processing but requires careful drying management to avoid spoilage.

Frequently Asked Questions

What is mucilage in coffee processing?

Mucilage is the thick, sticky, sugar-rich layer between the coffee cherry’s pulp and the parchment layer. Also called “honey,” it’s critical in honey processed coffee, as its retention affects the bean’s sweetness and body during drying.

How is honey process different from washed or natural coffee?

Honey process removes the coffee cherry’s skin and pulp but keeps some or all of the mucilage. Washed coffee removes all layers including mucilage via fermentation and washing, resulting in clean, bright flavors. Natural process dries the whole cherry, creating fruity, bold profiles but with more fermentation risks.

What do yellow, red, and black honey mean?

These refer to the color grade of honey process coffee beans, based on drying time and light exposure. Yellow honey dries fastest with full sun, red honey is dried slower with some shade, and black honey dries the slowest in minimal light, producing the sweetest and most complex cup.

Does honey process use less water than washed coffee?

Yes. Honey process requires significantly less water than the traditional washed method since it doesn’t involve fermentation tanks or extensive washing. However, it still needs proper infrastructure for drying.

Why is it called honey process?

It’s named for the sticky, golden mucilage left on the beans during drying, which resembles honey. This layer is high in sugars and impacts the coffee’s sweetness and body.

Which countries commonly use honey processing?

Honey processing is especially common in Costa Rica, but it’s also widely used in other Central American countries like El Salvador, Guatemala, and Honduras. It has spread wherever producers aim to balance sweetness, body, and sustainability.
