Coffee, the beloved beverage of millions worldwide, comes in various forms and processing methods. Among these, wet hulled coffee stands out as a distinctive and intriguing approach, particularly prevalent in Indonesia. In this article, we will delve into the world of wet hulled coffee, exploring its history, production process, characteristics, and the impact it has on the coffee industry.
A Brief History of Wet Hulled Coffee
Wet hulled coffee, also known as Giling Basah, has its roots in Indonesia, where it has been a traditional coffee processing method for centuries. The technique originated in the islands of Sumatra, Sulawesi, and Java, where coffee was first introduced by Dutch colonizers in the 18th century. The unique climate and geography of these islands, with their high humidity and limited drying facilities, led to the development of this innovative processing method.
The Evolution of Wet Hulled Coffee
Initially, wet hulled coffee was a response to the challenges faced by Indonesian coffee farmers in drying their coffee beans. The high humidity and frequent rain showers made it difficult to dry the coffee cherries using traditional methods. To overcome this, farmers began to remove the skin and pulp of the cherry, leaving the inner seeds to dry in their mucilage. This process allowed for faster drying and helped to preserve the coffee’s quality.
Over time, wet hulled coffee became an integral part of Indonesian coffee culture, with each region developing its unique twist on the processing method. Today, wet hulled coffee is highly prized for its distinct flavor profile and is sought after by coffee connoisseurs worldwide.
The Wet Hulled Coffee Production Process
The production process of wet hulled coffee is a labor-intensive and intricate procedure that requires great skill and attention to detail. Here’s an overview of the steps involved:
Step 1: Harvesting
Coffee cherries are carefully hand-picked by farmers, usually during the peak ripeness stage. This ensures that the coffee beans are of the highest quality and have the optimal balance of sugars and acids.
Step 2: Pulping
The coffee cherries are then processed through a machine called a pulper, which removes the outer skin and pulp of the cherry. This leaves the inner seeds, still covered in mucilage, intact.
Step 3: Fermentation
The coffee beans, still in their mucilage, are left to ferment in water tanks for a period of 24-48 hours. This process breaks down the mucilage and helps to develop the coffee’s flavor and aroma.
Step 4: Washing
After fermentation, the coffee beans are washed to remove any remaining mucilage and impurities.
Step 5: Drying
The coffee beans are then dried to a moisture level of around 30-40%. This is where the wet hulled process differs from other coffee processing methods. Instead of drying the beans to the usual 11% moisture level, they are left with a higher moisture content.
Step 6: Hulling
The dried coffee beans are then hulled, removing the parchment layer, leaving just the green coffee bean.

What is Wet Hulled Coffee and How Does it Differ from Other Coffee Processing Methods?
Wet hulled coffee, also known as Giling Basah, is a unique coffee processing method that originated in Indonesia. Unlike other methods, wet hulled coffee involves removing the skin of the coffee cherry, but not the pulp, and then drying the beans to a moisture level of around 30-40%. This process is distinct from washed coffee, which removes both the skin and pulp, and natural coffee, which leaves the skin and pulp intact.
The wet hulled method allows for a more efficient drying process, as the beans are not as sticky as they would be with the pulp still intact. This method also contributes to the distinct flavor profile of Indonesian coffee, which is often described as earthy, herbal, and full-bodied. The wet hulled process is particularly well-suited to the climate and geography of Indonesia, where high humidity and limited drying space can make it difficult to dry coffee using other methods.
