Papua New Guinea Organic Coffee from Purosa Estate

If you’ve been searching for a single-origin coffee with rich fruit and nut tones but want something beyond the usual Ethiopian or Colombian offerings, Papua New Guinea might be your answer. While not as famous as some other origins, PNG produces distinctive coffees with surprising clarity and complexity—especially when grown at high altitudes using traditional methods. But where exactly does this unique profile come from, and how is it produced?

The quick answer: Look for the Purosa Estate M10 JAS Organic coffee from Papua New Guinea’s Eastern Highlands. This AA-grade, washed coffee is grown between 1500–1600 metres and processed using both sun drying and mechanical drying to ensure consistency. It’s certified organic (JAS) and exports over 1,300 bags annually, with 85% going to Germany.

Papua New Guinea’s Coffee Origins

Coffee arrived in Papua New Guinea in the 1930s, brought from countries like Jamaica, Kenya, and Tanzania. By the 1950s, organised cultivation began, focusing on the mountainous regions of the central highlands—particularly in the provinces of Goroka and Madang. These areas provide ideal conditions for growing high-quality arabica, thanks to elevation, climate, and fertile volcanic soils.
