Chiang Mai (Mae Taeng, Omkoi, Mae Chaem)

Farming system

Smaller, more dispersed hill-tribe farms.

Less consistent agronomic support than Chiang Rai.

Processing reality

Washed; naturals appear experimentally.

Drying feasibility varies sharply by micro-valley.

Supply chain + power

Fewer established exporters → reliance on pilot projects.

Lots often assembled across multiple villages.

Buyer truth

Buy processor-specific, not region-wide.
