This fertile highland valley, shared by Western Highlands and Jiwaka, underpins a coffee- and tea-based economy.
The Wahgi (also Waghi) Valley is a fertile highland valley in central PNG, with the Waghi River flowing through it. Mount Hagen lies in the valley, and Jiwaka Province, whose economy rests on coffee, tea and human capital, is situated in the Waghi Valley. Western Highlands' economy is also centered on coffee.
An importer's page for Sigri lots from the valley gives 1,500-1,600 m and a harvest from June to November. Cherries are fully washed, fermenting for three days with washing every 24 hours before a final day of total immersion in water, then sun-dried and hand sorted. It lists Bourbon, Typica, Arusha, Blue Mountain, Mundo Novo, Catimor and Caturra among the varieties.
