Indonesia is effectively a huge archipelago, with islands stretching from Sumatra (the largest of the country’s islands) in the west over to Irian Jaya (part of which also comprises Papua New Guinea). Among its population of about 238 million people there is a strong sense of regional identity that has led to numerous internal conflicts, notably East Timor, which eventually won independence in the early 1990s and, more recently, the Aceh province in the north of Sumatra.
Indonesia is the second largest producer of robusta in the world after Vietnam and also produces a small but important amount of high quality arabica, with production concentrated in Sumatra and Java. Sumatran coffee has become increasingly valued over the past few years, offering good body coupled with a sweet spicey acidity. Sumatran coffee has a main crop and a fly crop.
