The washed process is the most common coffee processing method. It involves removing the pulp and skin from the coffee cherry before drying the beans. This process gives the coffee a clean and bright flavour profile that is often described as being acidic, fruity, and floral.
The washed process
The washed process of coffee begins with the harvesting of ripe coffee cherries. The cherries are then sorted to remove any unripe or damaged cherries. The next step is to remove the pulp and skin from the coffee cherries. This is done using a machine called a depulper. The depulper separates the beans from the pulp and skin, leaving behind a clean bean that is covered in a thin layer of mucilage. The mucilage is a sticky substance that surrounds the coffee bean. It is removed by soaking the beans in water and fermenting them for a period of 12-24 hours. The fermentation process helps to break down the mucilage and remove any impurities. Once the fermentation process is complete, the beans are washed thoroughly to remove any remaining mucilage. The beans are then dried in the sun or in a mechanical dryer.
Moisture percentage
The moisture content of washed process coffee is typically between 10-12% after drying. This is the ideal moisture content for storing and shipping coffee beans. Coffee beans with a higher moisture content are more likely to spoil, while coffee beans with a lower moisture content may be dry and brittle.
Flavour profile
Washed process coffee is known for its clean and bright flavour profile. The coffee is often described as being acidic, fruity, and floral. It may also have notes of chocolate, caramel, and nuts. The flavour profile of washed process coffee can vary depending on the coffee bean variety, the growing region, and the processing method. For example, Ethiopian washed process coffee is often known for its bright and fruity notes, while Colombian washed process coffee is known for its smooth and balanced flavour.
Brewing recommendations
Washed process coffee can be brewed using any method you prefer. However, many coffee lovers recommend using a pour-over or French press brewer to get the most out of the coffee's flavour. To brew washed process coffee using a pour-over brewer, simply grind the beans to a medium-coarse grind and place them in the filter. Slowly pour hot water over the grounds, starting in the centre and working your way out in a spiral motion. Allow the coffee to drip through the filter into your cup and enjoy! To brew washed process coffee using a French press brewer, simply grind the beans to a coarse grind and place them in the bottom of the press. Add hot water and stir gently to combine. Place the lid on the press and allow the coffee to steep for 4-5 minutes. Slowly press down on the plunger to separate the grounds from the coffee and pour yourself a cup.
Conclusion
Washed process coffee is a clean and flavourful coffee that is worth trying. If you are looking for a coffee with a bright, acidic, and fruity flavour, then washed process coffee is the perfect choice for you.
