Organic Coffee from Purosa Estate in Papua New Guinea

If you’ve ever wondered where your organic coffee really comes from—and whether those certifications mean anything on the ground—Papua New Guinea offers a compelling case. One of its most documented organic farms, Purosa Estate, produces coffee under strict conditions, with mechanical and sun drying, and exports to specialty markets around the world. This is how it works, and why it matters.

Purosa Estate produces JAS-certified organic AA-grade coffee annually, with 1,300 bags meeting export-grade quality. Of those, 85% go to Germany, and the rest to the US, UK, Australia, Japan, and New Zealand. The coffee is grown at 1500–1600 meters in the Eastern Highlands province of Goroka, Papua New Guinea.

The Origins of Coffee in Papua New Guinea

Coffee arrived in Papua New Guinea in the 1930s, brought from Jamaica, Kenya, and Tanzania. By the 1950s, planned cultivation began, focusing on the mountainous regions of Goroka and Madang in the central highlands. These areas, along with Eastern Highlands like Goroka where Purosa Estate is located, became the heart of PNG’s coffee production.

About Purosa Estate

Purosa Estate is situated in the Goroka region of Eastern Highlands Province. The farm spans 22,000 square meters and sits at an elevation of 1500–1600 meters. It grows coffee varieties including Typica, Bourbon, and some Catimor types (noted as “” and “” in the original), and produces exclusively washed-process coffee. The estate uses both sun drying and supplemental mechanical drying to ensure even moisture levels. The coffee is processed to AA grade, with beans sorted to 17 mesh or larger.

The farm is JAS-certified (Japanese Agricultural Standard) for organic production. The drying method is primarily natural sun drying, but to maintain consistency in moisture, mechanical drying is also applied. Every year, the estate carefully hand-sorts its output, ensuring high-quality beans reach global markets.

Getting to the farm isn’t easy—you typically take a helicopter to the region, then drive on rough roads to reach the estate. The surrounding area still shows remnants of past conflicts, adding to the remoteness and challenges of production.

Harvest and Processing Details

The coffee cherries are harvested between August and November. Flowering occurs from March to May. The processing method is fully washed (washed process), followed by natural sun drying and mechanical drying to achieve uniform moisture. The beans are sorted to meet the AA grade standard, with a screen size of 17 or higher.

The farm’s elevation, combined with traditional washed processing, contributes to a clean, bright cup profile. The estate is managed by Mr. Danie Lou, who oversees the organic certification and export operations. The coffee is packed in sacks marked with the JAS organic certification label.

Global Export Market

Out of the 1,300 bags of AA-grade coffee produced annually, 85% is exported to Germany, while the remaining 15% goes to the United States, Australia, the United Kingdom, Japan, and New Zealand. The estate’s focus on quality sorting and organic certification helps it meet the standards of specialty roasters worldwide.
