The Chinese fermentation tradition is the oldest documented in the world — oracle bone inscriptions (Shang Dynasty, 1600–1046 BCE) reference fermented grain beverages and condiments. The scope of Chinese fermentation is extraordinary: soy sauce (醬油), vinegar (醋), rice wine (黃酒), rice spirits (白酒), fermented black beans (豆豉), fermented tofu (腐乳), pickled vegetables (泡菜/酸菜), and the full spectrum of mould-fermented preparations.
The Chinese fermentation system — its breadth and foundational techniques. **醬 (Jiang — Fermented Paste Tradition):** The Chinese jiang tradition encompasses the full range of fermented soybean and grain pastes — the ancestor of Japanese miso and Korean doenjang. The specific Chinese contribution: the use of moulds (koji equivalents) to break down the soybean protein, producing glutamates, followed by salt preservation. Each regional jiang has a different character: - 甜麵醬 (tian mian jiang — sweet bean paste): Northern China, sweeter - 豆瓣醬 (douban jiang — bean paste): Sichuan, chilli-enriched - 黃醬 (huang jiang — yellow soybean paste): the most neutral, most ancient form **鎮江醋 (Zhenjiang Cu — Black Vinegar):** The most celebrated Chinese vinegar — made from glutinous rice, wheat bran, and specific bacteria, aged in clay jars for 1–3 years. The complexity of properly aged Zhenjiang black vinegar (Chinkiang) rivals aged balsamic — the longer aging produces more complex organic acids and aromatic compounds. Used for: Dongpo pork dipping, cold dressed preparations, hot and sour soup. **紹興酒 (Shaoxing Jiu — Rice Wine):** Fermented from glutinous rice and specific starter culture (酒藥 — jiu yao), Shaoxing rice wine is the foundational cooking wine of Chinese cuisine — used in red-braising, stir-fry marinades, and steamed preparations. Aged Shaoxing (花雕酒 — hua diao jiu) is drunk as a beverage; younger Shaoxing is used for cooking. **泡菜 (Pao Cai — Sichuan Pickles):** The Sichuan lacto-fermented vegetable tradition — vegetables in a salt brine with Sichuan peppercorn, dried chilli, and ginger. Different from Korean kimchi (no chilli paste, no fish sauce), different from German sauerkraut (more complex aromatics) — the Sichuan pao cai is crisp, clean-sour, and mildly numbing from the peppercorn.
