Natural Process: The Traditional Way to Dry Coffee Beans

Ever wonder why some coffees taste fruitier, sweeter, or more wine-like than others? One big reason lies in how the coffee cherry is processed after harvest. Among the oldest and most widespread methods is the dried—or natural—process, especially common in regions like Brazil and Ethiopia. This is how the majority of the world’s sun-dried specialty coffee begins.

Dried process coffee is the simplest and cheapest way to process coffee cherries. Unlike washed coffee, it uses unpulped, whole coffee cherries. After harvest, the cherries are spread out to dry in the sun, usually for around four weeks, until their moisture content drops to about 12%. That’s the basics—but there’s much more that goes into getting it right.

What Is the Natural or Dried Coffee Process?

The natural (or dried) process is the original method of preparing coffee beans for market. Instead of removing the fruit before drying, the entire coffee cherry is dried intact. This includes the skin, pulp, mucilage, and parchment—all layered around the green coffee seed inside. It’s the most traditional method and remains in wide use today, especially where water is scarce or processing infrastructure is minimal.

Where Is the Natural Process Most Common?

The dried process is most commonly used in Brazil and Ethiopia. These two countries account for a significant portion of the world’s natural-processed coffee. While most Arabica beans globally are washed or semi-washed, many Brazilian and Ethiopian coffees still rely on this traditional method. In Indonesia, a small amount of Robusta is also sun-dried, but washed processing dominates there.

How Is Coffee Dried Using the Natural Method?

After picking ripe coffee cherries, producers spread them out to dry on concrete patios, brick surfaces, or raised mats (often called African beds). The cherries need to be in full sunlight, and they are regularly raked or turned with a rake every few hours. This prevents fermentation or mold and ensures even drying. If rain or cold weather hits, the cherries must be covered to avoid damage.

This drying phase is slow and careful. Over roughly four weeks, the cherries lose moisture and harden. By the end, each cherry’s moisture level drops to approximately 12%, the industry benchmark for dry coffee. In Brazil, these dried beans are colloquially referred to as 'coco' at this stage—the outer shell turns dark brown and brittle, and you can often hear the beans rattling inside the husk.

Why Is Moisture Control So Important?

Getting the drying just right is critical. Under-dried beans remain too moist, making them vulnerable to mold or insect damage during storage. Over-dried beans become brittle and may break apart during hulling, the next step where the dried husk is removed. Either mistake can ruin an otherwise good crop. Proper drying preserves the bean’s integrity and sets the stage for quality roasting later.

Once dried, the coffee beans are stored in cool, dry cellars. Even at this stage, moisture continues to slowly evaporate from the bean. This resting period helps stabilize the coffee and can slightly refine flavor development before export or roasting.

What Makes Natural Process Coffee Different?

Natural process coffee tends to have more pronounced fruitiness, sweetness, and body. Because the bean is in contact with the cherry’s sugars and acids throughout drying, those flavors are absorbed into the seed. That’s why naturals often showcase blueberry, strawberry, or fermented notes, especially when well-executed. However, they can also be more unpredictable—if drying isn’t controlled, defects like over-fermentation or mold can spoil the cup.

Does the Natural Process Still Matter Today?

Absolutely. Despite the rise of washed and honey-processed coffees, natural processing remains vital—especially in regions with limited water access. It’s also valued for producing distinctive, often fruit-forward profiles that appeal to specialty roasters and drinkers. Many single-origin coffees from Ethiopia and Brazil are still proudly natural-processed, celebrated for their unique terroir-driven characteristics.

Recommended FrontStreet Beans Using Natural Process
