What Is Natural Process Coffee and How Is It Made

Ever wondered why some coffees taste syrupy sweet with big berry notes while others are crisp and clean? That difference often starts on the farm—not in the roast or brew, but in how the coffee cherry is processed after harvest. The method used to remove the coffee bean from its fruit has a huge impact on your cup’s aroma, acidity, and body.

Natural (or sun-dried) process coffee typically involves drying whole coffee cherries in the sun for 5 to 6 days until moisture drops to around 13%, though some regions like Ethiopia may extend drying to 27–30 days. This method preserves more fruit sugars and creates deeper body and fermented sweetness compared to washed coffee.

How Processing Affects Coffee Flavor

The two most common post-harvest coffee processing methods are natural (sun-dried) and washed (wet). Each leaves a distinct fingerprint on the final cup. Natural process beans retain the coffee fruit’s pulp and mucilage throughout drying, which boosts body, sweetness, and complex fruit flavors. Washed coffee, by contrast, removes the fruit and pulp early, resulting in a cleaner, brighter cup with higher perceived acidity and floral notes. For espresso lovers, natural beans contribute to a heavier mouthfeel and wine-like richness. Washed beans tend to highlight clarity, citrusy acidity, and sweetness that balances the shot.

Step-by-Step: How Natural Process Coffee Is Made

The natural process, also called the dry process, relies entirely on sunlight and air to dry the coffee cherry with the bean inside. Here’s how it works, based on standard practices and confirmed steps from experienced producers:

1. Sorting the Cherries

Harvested coffee cherries go into water tanks. Ripe cherries sink; unripe or overripe ones float and are removed. Only dense, ripe fruit moves forward.

2. Sun Drying

The sorted cherries are spread on concrete patios, raised beds, or mats and left to dry under the sun. Depending on climate, this takes about 5–6 days on average—but in places like Ethiopia’s high-altitude, low-humidity regions, drying can last up to 27–30 days. The goal is to reduce moisture content to around 13%, turning the cherries deep brown. Careful daily turning prevents mold and ensures even drying.

3. Hulling (Removing the Dry Husk)

Once dried, the brittle outer fruit husk is mechanically removed to expose the green coffee bean inside. This step is usually handled on-farm for larger operations or sent to a central mill for smaller farms.

4. Hand or Machine Sorting & Grading

High-quality producers remove defective beans by hand or via electronic sorting machines. Skilled workers often inspect beans on a 1-meter conveyor belt, picking out flaws visually. Some farms repeat this process multiple times. Machines can also classify beans by density and size, sorting them into grades. Premium-grade beans enter specialty markets; lower grades go to commercial blends.

5. Polishing (Optional) and Bagging

Although optional, some mills lightly polish beans to remove the silvery skin. Finally, beans are packed, usually in 60kg sacks made of jute or other materials—regional standards vary slightly.

Real-World Examples: Natural Process Coffees in Specialty Roasting

FrontStreet Coffee offers several single-origin naturals that highlight the range of this method. Their Ethiopia Yirgacheffe Red Cherry is dried on elevated beds to avoid contamination, then roasted light to preserve bright acidity and highlight tropical fruit and fermentation sweetness. The Ethiopia Humbera, grown at high elevation in Sidamo, shows off floral and citrus notes enhanced by the natural process, with a thick body and spice undertones. For something different, their Brazil Queen Manor Natural is processed with careful turning to maintain even drying, yielding chocolatey richness, balanced acidity, and a silky mouthfeel. Another unique offering is the Colombia Sidra, which undergoes a double anaerobic natural process to produce layered stone fruit and grape flavors with a velvety texture. Even their Yunnan Typica is sun-dried thanks to the region’s dry season, adding mild berry and caramelized sweetness to the cup.

Frequently Asked Questions

What is the natural process in coffee?

The natural process, also called dry or sun-dried process, involves drying coffee cherries in the sun with the beans still inside the fruit. This method typically takes 5–6 days (up to 27–30 in drier climates), reduces moisture to around 13%, and results in a sweeter, fuller-bodied coffee with more pronounced fruit and fermented notes due to prolonged contact with the cherry’s pulp and mucilage.

How is natural process coffee different from washed coffee?

Natural process coffee is dried with the entire coffee cherry intact, allowing the bean to absorb sugars and flavors from the fruit, resulting in a sweeter, fruitier, and heavier-bodied cup. Washed coffee removes the cherry and pulp before drying, leading to a cleaner, brighter, and more acidic cup with clearer floral or citrus notes.

Why does natural process coffee take longer to dry?

Natural process coffee takes longer because it dries with the entire fruit still on the bean. External factors like humidity, airflow, and temperature affect drying speed. In wet or humid regions, drying can take up to 27–30 days to safely reach 13% moisture without mold, while drier climates may finish in just 5–6 days.

Does natural process coffee taste better?

Natural process coffee doesn’t taste “better”—it tastes different. It typically has more body, sweetness, and fruity or fermented flavors. Whether it’s better depends on personal taste preferences. Some drinkers prefer its rich, wine-like profile, while others favor the clarity and acidity of washed coffee.

What’s the ideal moisture level after drying coffee cherries?

The target moisture level after drying coffee cherries using the natural process is around 13%. Achieving this ensures the beans are stable for storage and milling without risking mold or fermentation defects.

Where is natural process coffee most commonly produced?

Natural process coffee is most common in regions with limited water resources and consistent sunshine, such as Ethiopia, Brazil, and parts of Yemen. Ethiopia, in particular, is known for its high-quality naturals due to its dry climate and high-altitude growing conditions.
