Some of the innumerable islands of Indonesia have a long tradition of growing coffee. Java was the first island where Dutch colonial rulers grew coffee. At the beginning of the 20th century, rust disease destroyed almost the entire coffee industry on the island. Most plantations were then replanted with robusta, which is more resistant to fungi. Now Arabica is regaining lost ground in Java as well. The coffees are strong, rather low in acid, and sometimes deliberately stored for one to two years.
