Black Vinegar (Chinkiang / Zhenjiang)

Ingredient

What it is

A dark, aromatic aged vinegar from Zhenjiang in Jiangsu, made primarily from glutinous rice (and sometimes wheat, sorghum, or millet). The malt-vinegar of the Chinese pantry, near-black with a deep, mellow tang.

How it's made

Fermented in two stages (alcohol, then acetic) and aged, developing color and a smoky-malty complexity reminiscent of balsamic. Quality versions age longer for rounder acidity.

Flavor profile

Tart but soft and rounded rather than sharp, with woody, malty, faintly sweet and smoky depth. Far more complex than clear rice vinegar.

Culinary uses

The dipping vinegar for xiao long bao and dumplings (often with slivered ginger), a balancing splash in braises (hongshao), cold dishes, and noodle sauces. Pairs with dumplings, pork, ginger, soy.

Regional variations

Zhenjiang/Chinkiang is the benchmark. Shanxi aged vinegar (lao chencu), made from sorghum and aged even longer, is a sharper, more robust northern cousin. Baoning vinegar from Sichuan is another regional style.

Cultural & historical context

Zhenjiang vinegar carries centuries of reputation as one of China's "famous vinegars," and its protected status reflects a long regional craft tradition. Vinegar in Chinese cooking is as much about aromatic depth as acidity — a distinction Chinkiang embodies.
