It’s unclear when coffee planting arrived in Sumatra specifically. Java was the coffee king of Indonesia (aka the Dutch East Indies) for at least 100 years after cuttings first arrived from Ceylon before coffee of any significant volume was grown on other islands. And well into the 20th century, much of coffee grown throughout Indonesia was called Java. Of course coffee has come a long way in Sumatra over the last 100 years and been very responsive to the emergence of the specialty coffee sector, as evidenced by the number of Olam branded coffee from Sumatra. We have the full bodied, earthy and herbal coffees traditionally associated with Sumatran specialty coffee, but also the brighter citrus coffees you might not recognize as Sumatran.
