Coffee drinkers tend to focus on roast level when choosing a coffee, but processing method has an equally significant impact on what ends up in the cup. Understanding how coffee is processed is one of the fastest ways to make sense of why two coffees from the same country can taste completely different.

What Is Coffee Processing?

Coffee processing is the method used to remove the seed from a coffee cherry. Coffee beans are actually the seeds of a fruit, and like other stone fruits, there are several ways to extract that seed. The method chosen affects the seed's flavor development, which carries through roasting and into your cup. For more on how roast level then shapes that flavor further, see our guide to coffee roasting and flavor profiles.

Ways to Process Coffee

There are several main methods for processing coffee, with regional and experimental variations. Each method changes the sweetness, acidity, and body of the finished cup in distinct ways.

Natural Process

Also known as dry processing, the natural process is the oldest and most traditional technique. The whole coffee cherry, with the seed still inside, is dried in the sun for two to six weeks. During drying, the sugars and mucilage, the sticky substance that coats the seed, transfer into the bean and give it a sweeter, fruitier character. Once dried, a machine separates the dried husk and parchment from the seed.

Natural processed coffees tend to have a heavy body with deep, complex, fruit-forward notes that develop during the extended fermentation inside the intact cherry. Expect fruity, wine-like, and sometimes jammy flavors. These coffees work beautifully in a French Press, where their body and complexity have room to express themselves.

Washed Process

Washed processing, also called wet processing, is a faster and more controlled method. Machines called depulpers remove the seed from the cherry at peak ripeness. The remaining mucilage is broken down through fermentation and then washed away with water, after which the seeds are laid out to dry in the sun.

Washed coffees produce a cleaner, brighter, and more transparent cup than naturally processed coffees. The origin character, terroir, variety, and altitude, comes through most clearly with this method. Washed coffees are a natural match for pour-over brewing, where clarity and brightness shine.

Wet-Hulled Process

Wet-hulled processing, known in Indonesia as Giling Basah, is a method specific to Sumatra and other Indonesian islands. After depulping, the seeds are stored at high moisture levels rather than being dried immediately. They are then hulled while still at 30 to 40 percent moisture content before undergoing a final drying stage.

This process produces the distinctive earthy, chocolatey, and low-acid character that Sumatran coffees are known for. The cup tends to be heavy-bodied and savory, with notes of dark chocolate, cedar, and earth. If you have ever tasted a Sumatran coffee and found it unlike anything else, wet-hulled processing is the reason.

Honey Process

Honey processing is a hybrid of natural and washed methods, particularly popular in Central America. The cherry is depulped, but instead of going into a washing tank, the seed is laid out to dry with some or all of the mucilage still attached. The more mucilage left on, the sweeter and more complex the resulting coffee tends to be.

Honey processed coffees typically offer a syrupy sweetness and fuller body than washed coffees, with a more mellow acidity. The spectrum runs from white honey, with minimal mucilage, through yellow, red, and black honey, each with progressively more sweetness and complexity. For more on the honey process spectrum, see our guide to top coffee-producing countries, where Costa Rica's pioneering role in honey processing is covered in more detail.

Pulped Natural

Pulped natural processing is closely related to honey processing and the two terms are sometimes used interchangeably, particularly in Brazil. The key difference is that pulped natural coffees often undergo minimal mucilage removal followed by rapid drying, which retains a brighter, more restrained acidity than typical honey coffees. The result strikes a balance between fresh fruit brightness and clean texture, with subtle sweetness and a lighter body than a full honey process.

What's Your Flavor?

Processing method is one of the most powerful variables in coffee flavor, and understanding it gives you a meaningful way to navigate your choices. Pair it with an understanding of roast level and single-origin sourcing, and you have everything you need to find coffees you'll love consistently.
