Overview¶

Eastern Highlands Province is the historical birthplace of coffee in Papua New Guinea — the Goroka Research Station, where the original Jamaican Blue Mountain–origin Typica seedlings were planted in 1926, is located in the provincial capital of Goroka. The province grows Arabica at altitudes of 1,400–1,800 metres across the eastern ranges of the Highlands, producing a complex, chocolate and tropical fruit profile that is similar in character to Western Highlands but with distinct microregional variation. Goroka is also the site of the annual Goroka Show, one of PNG's most significant cultural festivals, reinforcing the region's identity as a cultural and commercial centre of the Highlands.

Geography and Terrain¶

Eastern Highlands Province occupies the eastern ranges of the PNG Central Highlands, with coffee cultivation concentrated around Goroka (1,600 m) and the Kainantu area to the east. The terrain is rugged highland ranges with deep river valleys, primarily draining to the Markham Valley and eventually the Pacific. The soils are a mix of volcanic Andosols and older Inceptisols, with volcanic influence less dominant than in the Wahgi Valley area of Western Highlands.

The province borders Western Highlands to the west and Morobe Province to the south and east. The Highlands Highway runs through Goroka, connecting the province to Lae (the main PNG coastal commercial port) and to Mount Hagen.

Farming Systems¶

A combination of smallholder farms and estates. Arokara Estate is one of the province's most internationally known producers, with a quality-focused washed processing programme. Cooperative structures and CIC-supported processing programmes serve smallholder farmers across the province.

Processing¶

Washed processing at estate and cooperative wet mills. The original Goroka Research Station (now a CIC facility) continues research into variety development and agronomic practice. Village-level smallholder processing is present alongside the more controlled cooperative and estate operations.

Varieties¶

Typica is the dominant variety, directly descended from the 1926 introduction. The Goroka Research Station has developed and distributed some improved local selections (including Arusha) from this original Typica base.

Cup Profile¶

Eastern Highlands estate washed Typica (1,400–1,800 m): complex, dark chocolate, tropical fruit (dried mango, guava, passionfruit), mild earth, stone fruit; soft round acidity; full body; cedarwood and mild spice in the finish. Slightly more variety in profile than Western Highlands due to the more fragmented terrain and soil variation across the province. SCA 83–87 for estate lots; commercial cooperative lots 79–83.
