What is Washed Coffee?
Washed coffee, also known as wet processed coffee, involves removing the cherry from the bean before drying. The cherries are typically mechanically de-pulped, then the remaining pectin is fermented and washed away. This process results in a clean and bright taste, with less fruity or fermented flavours. The washed coffee process is widely used in regions with access to ample water resources, as it requires a significant amount of water to wash away the remaining pulp and pectin. This process can also be more labor-intensive, as it involves more steps and careful monitoring of the fermentation process. Washed coffee is often favoured by specialty coffee roasters and connoisseurs for its clarity and acidity, as well as its ability to showcase unique flavour notes from the coffee's origin. However, this process can also result in a loss of some of the natural sweetness and body of the coffee, as the fruit sugars are removed during processing. Overall, the washed coffee process is one of the most common and widely used methods for producing high-quality specialty coffee.
It's worth noting that the washed process is a more controlled and consistent method of processing coffee compared to the natural or dry process. This is because the pulp and mucilage are removed from the coffee cherry soon after harvest, which helps prevent unwanted fermentation and other defects.
Washed coffee is often associated with brighter and cleaner flavours, which makes it a popular choice among specialty coffee roasters and enthusiasts. The lack of fruit pulp in the drying process allows for a more direct expression of the coffee's inherent flavour profile, which is particularly prized in certain coffee-growing regions known for producing complex and nuanced coffees.
However, the washed process is also more resource-intensive compared to other processing methods. It requires large amounts of water for the washing and fermentation stages, which can be a challenge in regions with limited water resources. Additionally, the use of water can lead to issues with water pollution if proper treatment and management practices are not in place.
Overall, washed coffee represents a significant portion of the specialty coffee market and is valued for its distinct flavours and consistency.
