Purosa Estate: Papua New Guinea’s Organic Coffee Farm

When you buy a bag labeled 'organic coffee from Papua New Guinea,' do you know where it really comes from—or how it’s grown? Many specialty drinkers are surprised to learn that PNG coffee has been cultivated from Jamaican, Kenyan, and Tanzanian seeds since the 1930s, with planned production starting in the 1950s. One lesser-known but high-quality source is the Purosa Estate in Eastern Highlands Province, where organic practices meet careful post-harvest handling.

Purosa Estate produces around 1,300 bags of AA-grade M10 JAS Organic coffee annually, with 85% exported to Germany and the rest going to the US, UK, Australia, New Zealand, and Japan.

The Origins of Coffee in Papua New Guinea

Coffee arrived in Papua New Guinea (PNG) over 70 years ago, during the 1930s, when seeds were introduced from Jamaica, Kenya, and Tanzania. These varieties adapted well to the island’s high-altitude regions. By the 1950s, the country began organized coffee cultivation, focusing on the mountainous areas of the central highlands—especially the regions of Goroka and Madang.
