Papua New Guinea’s Organic Coffee from Purosa Estate

Ever wondered where your specialty coffee really comes from—and whether it’s grown organically at high altitude with careful processing? If you’re seeking traceable, ethically produced single-origin beans with real cup character, Papua New Guinea offers an overlooked gem. One estate in particular stands out not just for its altitude and organic certification, but also for its unique post-harvest approach combining sun drying with mechanical precision.

Purosa Estate in Eastern Highlands Province, Papua New Guinea, produces around 1300 bags of AA-grade beans annually under JAS organic certification. About 85% of these are exported to Germany, with smaller volumes going to the US, UK, Australia, Japan, and New Zealand.

The Origins of Coffee in Papua New Guinea

Coffee first arrived in Papua New Guinea in the 1930s, brought from Jamaica, Kenya, and Tanzania. By the 1950s, organised cultivation began, concentrated in the mountainous regions of the central highlands—notably the regions of Goroka and Madang. These areas provided ideal conditions for growing quality arabica, and over time became home to some of the country’s most renowned estates.

About Purosa Estate

Purosa Estate is located in the Goroka region of Eastern Highlands Province, at an elevation between 1500–1600 metres above sea level. The farm spans 22,000 square metres and grows multiple coffee varieties including Typica, Bourbon, and Catimor. The harvest season runs from August to November, with flowering occurring between March and May.

The estate utilises a washed processing method. After pulping, the coffee is fermented, washed, and then dried using a combination of sun drying and mechanical drying to ensure even moisture levels. The beans are sorted to remove defects, with only the highest-quality AA-grade beans selected for export.

JAS (Japanese Agricultural Standard) organic certification confirms the estate follows strict organic farming protocols. The packaging bears the official JAS mark. The estate is managed by Mr. Daniearu, who oversees production and quality control.
