About
Coffee is one of PNG's most important export crops, with Arabica grown in the highlands (1200-1900m altitude) producing some of the world's finest specialty coffees. PNG coffee is known for its complex flavour profile. Smallholder farmers produce the majority of PNG coffee, making it a vital source of cash income for highland communities.
