How exactly do these differently named processing methods differ from conventional washing? From the perspective of Front Street, this article first sorts out the origins and steps of traditional washing, then analyzes the procedures and flavor characteristics of double washing, K72, and dry fermentation one by one, helping you understand the processing logic behind the unique fruit acidity of Kenyan coffee.

Coffee processing methods go far beyond just traditional washed—branches like dry washed and double washed each have their own intricacies. Traditional washed was born in 19th-century Jamaica, using a depulper and abundant water to shorten drying time, resulting in a clean, transparent cup; double washed originated in Kenya, adding an extra soaking step that gives rise to the K72 process and a full-bodied tomato and dried plum profile; dry washed, meanwhile, replaces large amounts of water with fermentation tanks, yielding flavors similar to honey processing. This article breaks down the origins, procedures, and flavor differences of these three washed methods one by one, and includes recommendations for Front Street Coffee's washed beans to help you find the cup that suits you.
