Nan / Phayao (eastern north)

Farming system

Arabica expansion zones; smallholders still learning best practices.

Coffee competes with maize and other crops.

Processing reality

Washed; drying can be clean in dry years.

Infrastructure thinner than Chiang Rai.

Supply chain + power

Exporter-driven pilots dominate.

Identity often bundled into “Northern Thailand” lots.

Buyer truth

Experimental origin; not dependable for repeat volume.
