What Is Natural Process Coffee? Costa Rica’s Villasarchi from Shumawa Estate

Ever wondered why some coffees taste syrupy sweet with ripe fruit and baked apple notes, while others are clean and bright? The answer often lies not just in the bean’s origin or variety, but in how it’s processed after harvest. In Costa Rica, one of the world’s most respected coffee-growing nations, processing methods play a massive role in defining flavor profiles. One method, in particular, has been turning heads for its bold sweetness and complexity: natural (or sun-dried) processing.

Natural processing means coffee cherries are dried whole—skin, pulp, and all—under the sun, usually for 2–4 weeks. This slow drying concentrates sugars and flavors inside the bean, resulting in sweeter, fruitier, and often more full-bodied cups. In Costa Rica’s high-altitude West Valley, this method brings out intense notes in the unique Villasarchi variety.

Why Costa Rica’s Climate Is Ideal for Natural Processing

Costa Rica sits in Central America’s narrow land bridge, where Pacific and Atlantic winds regulate temperatures, and elevations reach up to 2,000 meters. Most of the country’s best coffee grows on volcanic soils rich in minerals and under cool high-altitude conditions that slow cherry maturation. These factors help develop dense beans with complex potential—perfect for highlighting through natural drying.

The country’s coffee production is relatively small, yielding about 1.6 million 60kg bags annually, according to the ICO. But its output is known for exceptional cup quality and premium pricing, often outperforming larger producers like Guatemala or Honduras. Most of Costa Rica’s coffee comes from eight defined regions, and the West Valley is one of the most dynamic.

West Valley & Shumawa Estate: A New Wave of Natural Processing

The West Valley (Valle Occidental), particularly the district of Orange, is home to Shumawa Estate—an estate focused on minimal environmental impact and high-quality specialty lots. Sitting between 1,670 and 1,790 meters above sea level, the farm benefits from a high diurnal temperature range and deep volcanic soils. Owner Francisco Mena, formerly in coffee trading, preserved much of the area’s native forest and planted coffee on only a portion of the land to maintain ecological balance.

Shumawa uses innovative farm waste management: instead of burning fallen trees or brush, they chip organic material and compost it with fertilizers. This closed-loop system feeds the soil naturally while protecting the surrounding ecosystem.

Villasarchi: A Unique Coffee Variety for Natural Processing

Shumawa Estate grows Villasarchi, a mutation of Red Bourbon that ranked among the top 13 coffees in Costa Rica’s prestigious Cup of Excellence. This high-elevation-tolerant variety is known for its vibrant acidity, intense fruitiness, and complex aromatic profile. It typically shows bright citrus, delicate floral hints, and deeper notes of raisin and nuts—all traits that natural processing can amplify.

Villasarchi thrives in windy, cool high-altitude environments, making the West Valley an ideal home. The variety’s inherent sweetness and juicy acidity respond exceptionally well to sun-drying, allowing for a layered cup with both brightness and body.

How Natural Processing Works at Shumawa Estate

At Shumawa, coffee cherries are carefully harvested at peak ripeness. Rather than removing the fruit skin and fermenting the beans, they’re laid out whole to dry in the sun. The cherries are regularly turned to prevent mold and ensure even drying—a critical factor in natural processing. This slow dehydration concentrates the sugars from the pulp directly into the seed, creating the sweet, fruity characteristics associated with naturals.

The estate’s elevated location provides plenty of sunshine and a big daily temperature swing, aiding a stable and gradual drying process. The entire lot is classified as SHB (Strictly Hard Bean), indicating beans grown above 1,200 meters with dense structure and slow maturation—ideal candidates for natural methods.

Shumawa applies no additional fermentation steps or pulped natural techniques. The result is a 100% natural-process coffee that showcases the pure expression of the Villasarchi variety and the West Valley terroir.

Flavor Profile: What to Expect from This Natural Lot

This particular lot of Villasarchi from Shumawa Estate, processed naturally, was featured with tasting notes of honeyed apple, dried berries, and yellow fruit tones. These descriptors point to a cup that’s likely sweet and lush, with a balanced structure and prominent stone and orchard fruit character. Such profiles are common in well-executed natural lots, where slow sun drying preserves and intensifies the fruit sugars.

It’s a great example of how careful farming, varietal selection, and processing choices combine to create a unique specialty coffee experience.

Frequently Asked Questions

What is natural (sun-dried) coffee processing?

Natural processing involves drying coffee cherries in their entirety—skin, pulp, and all—under the sun. The cherries are spread out on patios or raised beds and turned regularly to dry evenly over 2–4 weeks. This method allows sugars from the fruit to be absorbed into the bean, resulting in a sweeter, fruitier cup profile.

Why does natural processing give coffee more fruitiness?

Because the coffee bean remains in contact with the fruity pulp and mucilage during drying, natural processing allows more of the sugars and aromatic compounds from the fruit to ferment and infuse into the seed. This leads to enhanced sweetness, berry-like flavors, and often winey or fermented notes in the final cup.

Where is the West Valley in Costa Rica?

The West Valley (Valle Occidental) is one of Costa Rica’s eight recognized coffee-growing regions. It features high altitudes, volcanic soils, and a climate with strong day-night temperature variation, making it well-suited for growing high-quality specialty coffee varieties like Villasarchi.

What is Villasarchi coffee variety?

Villasarchi is a natural mutation of the Red Bourbon coffee variety. It’s known for its resilience to wind, preference for high altitudes, and complex cup profile featuring bright acidity, citrus, floral notes, and deeper tones of raisin and nuts. It performed in the top 13 of Costa Rica’s Cup of Excellence.

Does Shumawa Estate use any special techniques in its natural processing?

Yes. Shumawa dries its natural lots carefully under the sun with regular turnover to ensure even drying. The estate avoids burning farm waste, instead recycling wood and organic debris into compost.
