Zhenjiang aged black rice vinegar, malty and sweet, GI-protected since 2001. The vinegar of Yangtze cuisine.
Zhenjiang, Jiangsu. The Hengshun house was founded in 1840 by Zhu Zhaohuai, who first brewed 'baihua' rice wine and around 1850 fermented the spent lees with chaff into the prototype of this vinegar. The technique uses solid-state fermentation: cooked glutinous rice + wheat bran + chaff piled in pits, turned daily for about 20+ days, then aged 6 months minimum (up to several years).
Hengshun's six-year reserve (Liunian Chen) is the Sichuan-pepper-tip of black vinegar — order it for crab and hairy crab dipping. The plain three-year jar is the cooking standard.
Near-black, viscous, smoky-malty on the nose — closer to balsamico than to white vinegar. Sour first, then a long sweet-malt tail; almost no sharp acid bite. Cuts pork-rib fat and oils a dumpling dip with two drops of sesame oil.
Solid-state fermentation (vs. liquid-state for clear vinegars) lets Maillard browning run during the second 'roast pit' stage — that's where the color and malt note come from. Aging in clay urns (the 'sun-day, dew-night' open-jar method) drives 5–8% evaporation per year, concentrating both acid and sweetness.
Variations
Hengshun (Zhenjiang, the GI flagship); Shanxi laochencu (drier, sharper, sorghum-based, from Taiyuan and Qingxu); Baoning vinegar (Sichuan, herb-infused with Chinese medicine flavorings, used in Sichuan dipping sauces).

Smoke fermented mash gently over straw fires; mature 3+ years.
Watch outSmoke gently over straw — you want the mash to color and pick up a soft malt-smoke note, not scorch; too hard a fire turns it acrid.

Press; filter; bottle. Grade by age — older is richer and more aromatic.
Watch outJudge by age and aroma — a well-aged one pours dark and glossy with a deep malty nose; that concentration comes from years of urn evaporation.
