Western Highlands (Mt Hagen, Tambul, Enga)

Farming system

Higher altitudes than the east; cooler nights.

Villages even more remote; access roads can be seasonal.

Processing reality

Washed exists, but logistics delay first drying.

Drying is slower; cold nights increase under-dry risk.

Supply chain + power

Fewer mills → longer collector chains.

Specialty succeeds only with vertically integrated exporters.

Buyer truth

Can be exceptional, but variance is extreme without tight control.
