Shanxi Fen Jiu Vinegar Culture (山西醋文化)
Shanxi Province — particularly Taiyuan region
Shanxi Province is China's vinegar heartland, producing Mature Shanxi Vinegar (Chen Cu) — aged minimum 3 years, up to 10+ years — with far more complexity than ordinary rice vinegar. Key brands: Donghu Vinegar (东湖), Zhenjiang Hengshun (different region but similar prestige). Shanxi people are said to consume more vinegar per capita than any other Chinese province. Used in noodle dressings, soups, marinades, and at table.
