Papua New Guinea
Papua New Guinea's arabica grows in the rugged highlands — the Wahgi Valley, Eastern Highlands and Simbu — where smallholder 'garden' plots and the Typica-derived Arusha variety dominate.
History
Coffee was introduced to Papua New Guinea in the late 19th century, though commercial production only gained momentum in the 1920s using Jamaican Blue Mountain arabica seeds. The industry expanded significantly during the 1960s and 1970s, bolstered by improved infrastructure and a global market advantage when Brazilian frost events reduced international supply. Following the country's independence in 1975, the sector shifted from large foreign-owned plantations to a model dominated by local smallholders who now produce over 90% of the crop. Despite facing economic challenges from price volatility since the late 1990s, the industry has maintained its position by focusing on high-altitude, shade-grown specialty coffee. Today, the sector relies on a network of smallholder 'gardens' where farmers process coffee to the parchment stage before transporting it to central mills for export.
