At OUR, we believe that understanding the coffee production process can enhance your appreciation for that perfect cup of coffee. One essential step in coffee bean production is wet processing. But what exactly does wet processing mean, and how does it impact the flavor of your favorite brew?
Wet processing refers to the method used to process coffee cherries before they are exported, roasted, and eventually consumed. This processing method plays a significant role in flavor enhancement, similar to the origin of the beans themselves.
During wet processing, water is used to remove the skin and pulp from the cherry, separating any defective beans and fermenting the remaining beans to eliminate the sticky-sweet mucilage layer. The beans are then rinsed and dried. This meticulous process is known for producing cleaner and more consistent flavors compared to other processing methods.

The Fully Washed Process (Wet Process)
The fully washed process, also known as the wet process, is the most commonly used processing method in specialty coffee producing countries. It involves using water to wash the skin and pulp off the coffee cherries, separating the defective beans, and fermenting the remaining beans to remove the mucilage layer. After fermentation, the beans are rinsed and dried. The wet process guarantees a cleaner and more consistent flavor profile compared to other methods. It is preferred by farmers and large batch roasters due to its ability to maintain quality control and flavor consistency.
The fully washed process starts by handpicking only the ripest coffee cherries. Once harvested, the cherries are pulped within hours to remove the outer layers and reveal the beans inside.
The pulped coffee beans are then fermented in water tanks for a specific duration, allowing enzymes to break down the remaining mucilage. This fermentation process creates unique flavors and helps remove any impurities, resulting in a cleaner cup profile.
After fermentation, the beans are washed multiple times to remove any traces of mucilage. This thorough rinsing ensures that only the highest-quality beans move forward in the process.
The washed beans are then laid out to dry either on patios or raised beds, where they are regularly turned and monitored for consistent drying. This step is critical in maintaining the quality and flavor characteristics of the coffee.
Once the beans are fully dried, they are hulled to remove the dried parchment layers, revealing the green coffee beans. These beans are then ready for export, roasting, and brewing.
Benefits of the Fully Washed Process
The fully washed process offers several advantages that make it the preferred choice for many coffee producers and roasters:
- Quality Control: The wet process allows for greater control over the coffee’s quality by removing defects and impurities through meticulous washing and fermentation.
- Flavor Consistency: The process ensures a more consistent flavor profile across batches, providing a reliable taste experience for coffee enthusiasts.
- Enhanced Aroma: The removal of the mucilage layer during fermentation results in a cleaner and more pronounced aroma in the final cup.
- Bright Acidity: The wet process often leads to coffees with bright and lively acidity, which can be a desirable flavor characteristic for many coffee lovers.
With its emphasis on quality control, flavor consistency, and aroma enhancement, the fully washed process continues to be a preferred method in specialty coffee production.
|Advantages of the Fully Washed Process
|Lowers the risk of defects and ensures high-quality beans
|Produces coffee with a consistent taste experience
|Results in a cleaner and more pronounced aroma
|Delivers coffees with vibrant and lively acidity
The Natural Process (Dried/Sundried Process)
The natural process, also known as the dried or sundried process, is a simpler yet more laborious method of coffee processing. It involves drying the whole coffee cherry intact on raised beds or large patios. Throughout the drying process, the cherries are turned and raked to prevent rotting. Once fully dried, the cherry’s layers are removed, and the coffee beans are extracted.
The natural process produces a unique flavor profile characterized by fruity flavors, lower acidity, and a fuller body. The extended contact between the bean and the fruit during the drying process imparts intense fruity notes to the coffee. This natural method also tends to result in a lower level of acidity compared to other processing methods, making it an excellent choice for those who prefer a milder cup of coffee with a smoother finish.
However, it’s important to note that the natural process can be more inconsistent in terms of quality. The varying levels of sugars and alcohols present in each bean can lead to differences in flavor and potential defects. Nevertheless, many coffee aficionados appreciate the natural process for its distinct flavor and its ability to showcase the natural characteristics of the coffee beans.
To give you a visual representation of the natural process, here’s an image depicting coffee cherries drying under the sun:
Advantages of the Natural Process:

Despite its challenges, the natural process continues to be a popular choice among coffee lovers seeking a distinctive and flavorful experience. In the next section, we will explore the selective picking method for wet method processing, which further enhances coffee quality and flavor.
Selective Picking for Wet Method Processing
In the world of specialty coffee, wet method processing is highly regarded for its ability to yield exceptional quality beans. One crucial factor that contributes to this superior quality is selective picking. Unlike strip-picked beans, where all cherries from a branch are harvested at once, selectively picked coffee beans are chosen individually, ensuring only the ripest cherries make it into the final product.
Selective picking involves the meticulous manual inspection of coffee trees, as experienced farmers carefully select and harvest cherries at the peak of ripeness. This labor-intensive process may take longer, but it guarantees that only the highest-quality cherries are chosen for wet method processing.
By prioritizing selective picking, we filter out underdeveloped or overripe cherries that could negatively impact the flavor and quality of the coffee. This attention to detail and commitment to excellence set the foundation for wet method processing to work its magic.
The benefits of selective picking extend beyond just the elimination of defective cherries. Since only the best cherries make it to the wet processing stage, there is a higher concentration of sugars and aromatic compounds within the beans, which ultimately translates to a more flavorful and aromatic cup of coffee.
Furthermore, the selectivity in picking ensures consistency in the beans’ ripeness, leading to a more even and uniform coffee roast. This consistency is vital for achieving optimal extraction during brewing, as it allows for better control over the coffee’s flavor profile.
The Wet Method Processing Journey
Once the finest cherries have been selectively harvested for wet method processing, the coffee beans undergo a meticulous series of steps to bring out their full potential. This process involves de-pulping, fermentation, rinsing, and drying.
1. De-pulping: The first step is to remove the skin and pulp from the cherry, leaving only the bean. This is typically done using a machine that separates the outer layers from the bean.
2. Fermentation: After de-pulping, the beans are left to ferment in water tanks for a specific period. Fermentation helps break down the remaining sticky-sweet mucilage layer that clings to the beans.
3. Rinsing: Once fermentation is complete, the beans are thoroughly rinsed to remove any leftover mucilage. This step ensures the beans are clean and ready for the final drying stage.
4. Drying: The beans are carefully spread out on raised beds or patios to dry naturally under the sun. This slow and precise drying process allows the beans to reach the optimum moisture level without compromising their inherent flavors.
Throughout the wet method processing journey, the selective picking of ripest cherries ensures that the beans possess and maintain their exceptional quality, providing coffee enthusiasts with a truly exquisite and nuanced experience.
