Coffee trees were originally brought to Indonesia in the early 19th century by the Dutch, who sought to break the world-wide Arabic monopoly on the cultivation of coffee. Within a few years, Indonesian coffee dominated the world’s coffee market. Yet by the end of the century disease completely destroyed the crop. Coffee trees were successfully replanted and quickly gained a large share of the world market until the plantations were ravaged again during World WarII. “Mandailing”, spelled here correctly, is technically an ethnic group in Indonesia, not a region, as is Batak.
