Xuanwei ham is protected as a geographical indication product under the current GB/T 18357-2008 national standard, whose status page records that it remains in force after a 2025 review. A 2021 Qujing municipal report describes the production chain at a local processing plant: shaping the leg, salting, washing and drying, followed by months of fermentation under monitored temperature and humidity. The report is a snapshot of one enterprise, not a complete account of every household or producer.
The sequence matters because fermentation is not a single magical stage. Salt enters the prepared meat; washing and drying alter the surface conditions; the hanging room provides a managed environment in which the product changes over time. The municipal article describes a ten-month period of repeated checks by a workshop manager. That detail shifts the story away from a romantic image of ham simply hanging in mountain air: contemporary production combines craft judgment with process control.
