Processing Guide

Honey Processed Coffee

Halfway between washed and natural, honey processing creates some of the most complex and rewarding cups in specialty coffee. Discover how mucilage, fermentation, and drying time shape white, yellow, red, and black honeys.

The Basics

Introduction to Honey Processing

Honey processing is one of the most exciting and nuanced methods used to prepare coffee after harvest. Despite the name, it has nothing to do with honey the sweetener—the term refers to the sticky, honey-like texture of the coffee beans as they dry with mucilage still clinging to the parchment. The result is a cup that bridges the gap between the clean clarity of a washed coffee and the wild fruitiness of a natural coffee.

To understand honey processing, it helps to first understand the two main processing techniques it sits between—and why producers developed honey as a deliberate middle ground.

The Spectrum

General Processing Techniques

There are two main methods for processing coffee after it has been picked. Understanding these two endpoints is essential to grasping where honey processing fits in.

Washed Processing

  • The skin and mucilage are removed from the cherry
  • The coffee is washed down to parchment
  • Dried as clean parchment
  • Produces a sweeter, cleaner cup that highlights origin character

Natural Processing

  • The whole cherry is laid out to dry intact
  • Once fully dried, the cherry is dry milled to remove the dried fruit
  • Produces funky, interesting flavors driven by fermentation
  • Results can be unpredictable—brilliantly complex or inconsistent

Washed coffees tend to give you a sweeter, cleaner cup where the terroir and varietal character shine through. Natural coffees can produce wonderfully funky and interesting flavors born from fermentation, but the process is inherently less predictable.

The Best of Both Worlds

Honey: Halfway Between

Honey processing sits halfway between washed and natural. The skin and some of the mucilage are removed mechanically using a demucilaging machine, but—unlike washed processing—the coffee is not washed clean. Instead, it is laid out to dry with the remaining mucilage still intact on the parchment. Once dried, the coffee is dry milled to remove the dried mucilage and parchment.

The mucilage left on the bean during drying is high in sugar. As it dries, controlled fermentation occurs within this sugary layer, imparting sweetness, body, and complexity to the cup. The degree of fermentation—and therefore the flavor impact—depends on how much mucilage remains and how the drying is managed.

The Color Spectrum

White, Yellow, Red & Black Honeys

The central principle behind the different colored honeys is controlling the fermentation of the mucilage, which is high in sugar. Increased heat dries the coffee faster, which stops fermentation sooner. A long, drawn-out drying process prolongs fermentation, allowing more sugars to break down and more complex flavors to develop.

Two main techniques are used, particularly in Costa Rica and El Salvador, to create the spectrum of honey colors:

Technique 1: Degree of Mucilage Removal

By calibrating the demucilaging machine, producers control how much mucilage remains on the parchment. Less mucilage means less sugar available for fermentation and a lighter, cleaner result. More mucilage means more fermentation potential and a heavier, fruitier cup.

White Honey

~25% mucilage remaining

Least fermentation

Yellow Honey

~50% mucilage remaining

Mild fermentation

Red Honey

~75% mucilage remaining

Moderate fermentation

Black Honey

~100% mucilage remaining

Most fermentation

Technique 2: Time Before First Turning

The second lever producers pull is how long the coffee sits on the drying bed before it is first turned. Turning exposes more surface area and speeds up drying. Leaving the coffee undisturbed allows fermentation to continue longer.

Lighter Honeys

Turned after 1 day

Faster drying, less fermentation

Darker Honeys

Left 2–3+ days before turning

Slower drying, more fermentation

Black Honeys

Dried under shade

Slowest drying, maximum fermentation

The Bottom Line

Get In My Mug

There are lots of ways to achieve similar goals when it comes to honey processing, and there is no standard terminology across the industry. A "red honey" from one farm may not mean the same thing as a "red honey" from another. What matters is that the producer is intentionally controlling the amount of mucilage and the speed of drying to shape the cup profile.

Whether you're drawn to the clean sweetness of a white honey or the rich, fruit-forward complexity of a black honey, this processing method showcases the incredible range of flavors that can be coaxed from a single coffee cherry—without adding anything at all.

The Honey Spectrum

Lighter Honeys (White / Yellow)

Cleaner, sweeter, more origin-forward. Less mucilage, faster drying, minimal fermentation.

Darker Honeys (Red / Black)

Heavier body, fruit complexity, fermentation-driven flavors. More mucilage, slower drying, extended fermentation.
