Quảng Trị / Quảng Nam (central highlands pockets)

Farming system

Lower, warmer altitudes; Arabica struggles agronomically.

Smallholders with mixed income sources.

Processing reality

Washed exists but fermentation runs fast.

Drying is easier than Sơn La but quality ceiling is lower.

Supply chain + power

Strong commodity pull.

Specialty lots depend on single-buyer programs.

Buyer truth

Not a core specialty origin; treat as experimental.
