Vasket Grønne Kaffebønner

Washed coffee, often referred to as wet-processed coffee, is known for its clean and bright cup profile, with higher acidity and exceptional flavour clarity. This process brings out the intrinsic qualities of the coffee bean—such as its terroir, varietal, and origin—without being masked or altered by the processing method. Because of this, washed coffees are celebrated for their consistency and predictability, making them appealing to a broad range of coffee drinkers.

The result is a coffee with crisp, vibrant, and nuanced notes. Washed coffees are an excellent choice for those who value balance and clarity, as they allow the true essence of the bean to shine through. Their clean and refined profile makes them particularly popular among discerning coffee lovers and professionals alike.

Washed coffee, also known as the wet process, involves depulping the cherries to remove the skin and fruit, followed by a fermentation stage lasting 8 to 72 hours. During this time, the mucilage surrounding the beans is broken down. After fermentation, the beans are thoroughly washed to remove any remaining residue and are then dried, typically on raised beds or patios.

Fully washed coffee is a variation of this process that eliminates the fermentation stage altogether. After the cherries are depulped, the mucilage is removed immediately using a pressurised water system. The beans are then dried, just as in the washed process. This method produces an even cleaner and more consistent flavour, as it relies entirely on the quality of the coffee cherries and their growing conditions. Fully washed coffee is often considered the most accurate representation of a coffee's origin, as no pulp or mucilage influences the final taste.

The preference for washed or natural coffees depends largely on taste and the coffee experience being sought. Each processing method creates distinct flavour characteristics, suited to different palates.

Washed coffees are highly regarded for their clarity, acidity, and precision. They provide a pure expression of a coffee’s origin, highlighting subtle flavours that reflect the environment and conditions in which the beans were grown. This makes washed coffees an excellent showcase for high-quality beans, where the inherent taste profile can shine without interference from the processing.

Natural coffees, on the other hand, are known for their full body, fruity intensity, and sweetness. The natural process, where the coffee cherry dries with the fruit still intact, imparts rich, bold flavours and a unique complexity to the cup. These coffees are often described as having vibrant fruitiness, sometimes with a slightly wild or "funky" edge. They tend to offer a more pronounced and robust drinking experience.

Both approaches have their strengths. Washed coffee is ideal for those who prefer a clean, bright, and balanced flavour profile, while natural coffee appeals to those seeking bold, fruity, and richly textured flavours. Neither is inherently better, and both offer opportunities to explore the diverse world of coffee.

Washed processing, also known as the wet method, is a cornerstone in the world of speciality green coffee, prized for producing beans with remarkable clarity, crisp acidity, and refined flavor profiles.

This meticulous process involves removing the coffee cherry’s outer layers before drying, which allows the bean’s intrinsic qualities, such as varietal character, terroir, and altitude influence, to shine with greater precision. By eliminating the influence of fruit pulp during drying, washed green coffee delivers clean, transparent cup profiles that many roasters rely on for consistent and predictable outcomes.

For roasters, washed green coffee beans offer a reliable foundation for exploring delicate flavor nuances, especially in single-origin offerings. Whether you're sourcing for a seasonal espresso menu or a competition-grade filter roast, washed coffees provide a balanced acidity, a well-structured body, and a bright cup that tells the story of its origin with integrity.

Whether you're a home roaster experimenting with your first small batch, a professional roaster curating a high-quality portfolio, or a wholesaler supplying the wider coffee industry, our selection of washed green coffee beans offers the precision and traceability you need to elevate your roasting craft.

Washed processing is a controlled, water-intensive method that separates the coffee seed from its fruit layers before the drying stage, ensuring minimal external influence on the green bean’s chemistry. After harvesting, ripe cherries are mechanically depulped, leaving behind mucilage that is then broken down through natural fermentation, typically lasting between 12 to 72 hours, depending on climate and altitude.

Once fermentation is complete, the beans are thoroughly rinsed to remove all residual mucilage and then laid out to dry evenly, either on raised beds, patios, or mechanical dryers, until they reach a stable moisture level, often around 10–12%.

From a roasting standpoint, this processing method results in green beans that are dense, uniform, and structurally sound, offering predictable thermal behavior during the roast. Roasters can expect more control in development stages, with minimal risk of uneven roast or internal scorching, making these beans ideal for precision profiling. Washed green coffees are known to respond well to subtle adjustments in heat application, especially during the Maillard and post-crack phases.

Because the process enhances intrinsic bean quality rather than overlaying it with external flavors, washed coffees often become the go-to choice for showcasing terroir and varietal purity in a roasting program.

From Farm to Drying Bed,  A Clean Path to Clarity

The washed process begins at the point of harvest, where only fully ripe cherries are selected. These cherries are then passed through a depulping machine, which gently removes the outer skin. The sticky layer underneath, called mucilage, is left to ferment in clean water tanks for a day or two, allowing it to naturally break down. After fermentation, the beans are thoroughly rinsed to remove any remaining residue. Finally, they’re dried slowly and evenly, either under the sun or using mechanical dryers, until they reach ideal storage moisture.

How It Shapes the Cup

This clean, water-based process produces bright, articulate coffees with sparkling acidity and transparent flavor expression. Roasters often notice citrus zest, florals, stone fruit, and refined sweetness, especially in high-altitude lots. The absence of fruit pulp during drying allows the bean's original characteristics to shine without interference, resulting in a precise and elegant flavor profile.

Roasting Opportunities

Washed green coffees are a natural fit for lighter roasts, where their complex acidity and aromatics can take center stage. For those aiming to balance vibrancy with a touch of sweetness, a medium roast can offer a rounded cup with a silky body and balanced structure. Thanks to their uniform density and clean profile, these beans are also ideal for cupping tables, single-origin features, and competitive blends.

Versatile and Transparent, A Roaster’s Reliable Canvas

Washed green coffee beans are exceptionally versatile, making them a smart choice for a variety of roasting goals. Their clean and articulate profile makes them particularly well-suited for single-origin offerings, where clarity and traceability are essential. These coffees showcase terroir with precision, helping roasters emphasize origin stories and differentiate their menu.

For those building blends, washed coffees can add structure and brightness without overpowering other components. Their balanced acidity and clear sweetness make them ideal as a base or highlight element in espresso or filter blends, especially when aiming for complexity with consistency.

Room to Explore and Refine

Because washed beans respond predictably to heat, they offer an excellent opportunity for profiling and experimentation. Roasters can explore subtle adjustments in development time, charge temperature, or airflow, knowing the green coffee will respond with clarity. This makes them especially valuable for cupping trials, educational programs, or exploring roast curve variations across different machines.
