Java Preanger Fully Washed Grainpro is sourced from family-owned farms located in the Pangalengan district, Bandung Regency on the island of Java, Indonesia. Wildan Mustofa and Atieq Mustikaningtyas, a husband and wife team, started cultivating coffee in 2011 as a means of erosion control and soil conservation on the steep terrain near where they were cultivating vegetables, seed potato, and tea. They also encouraged their neighbors who now also grow coffee on 2 to 5 acre plots. Their collective coffee and shade trees, such as eucalyptus and pine, have very good foliage and root systems that protect the soil from erosion and increases water holding capacity, which is very important because the Bandung highland is a catchment area for the Citarum basin. Approximately 40 million people in West Java Province and Jakarta Capital Territory depend on the Citarum river for Irrigation and domestic water use. Wildan and Atieq have also used coffee revenue to purchase land and provide construction funds for a local school that gives children closer access to education through high school.
