Most of Kenya's coffee is produced by smallholders delivering to factories (central processing units) who predominantly produce Washed coffees. Estates are also best-known for their Washed lots. The Washed process in Kenya may vary slightly from place to place, but it generally contains a soaking step that is unique to this growing country. First the coffee is picked ripe and depulped the same day, then it is normally fermented in open-air tanks made of concrete or cement for 24–48 hours. It's then washed thoroughly using water channels before being soaked underwater for 12–72 hours. It is then spread on raised beds to dry.
