Method wines (法酒), the refilling wines of chapter 67法酒
Chapter 67 of the 6th-century Qimin Yaoshu gives a family of "method wines", which the text says all use spring-wine qu, started on set days of the year. Most start on the 3rd day of the 3rd month; the Shijing version starts on the 7th of the 7th month and the roasted-wheat version on the 2nd of the 2nd month. In the main proso-millet version, the qu soaks for seven days and then millet goes in, in growing amounts, until the jar is full. Once half is drunk, more cooked millet alone refills it.

Chapter 67 of the 6th-century Qimin Yaoshu gives a family of "method wines", which the text says all use spring-wine qu, started on set days of the year. Most start on the 3rd day of the 3rd month; the Shijing version starts on the 7th of the 7th month and the roasted-wheat version on the 2nd of the 2nd month. In the main proso-millet version, the qu soaks for seven days and then millet goes in, in growing amounts, until the jar is full. Once half is drunk, more cooked millet alone refills it. Made in 4 steps over 7 days. The longest step, soak the qu on the 3rd day of the 3rd month, takes 7 days (Jia Sixie 2026).
The method wines start on fixed calendar days with matching measures (3 jin 3 liang, 3 dou 3 sheng, or 9 dou of each), and they are refilled with grain as they are drunk, so one jar lasts a summer. The text says all use spring-wine qu, though the roasted-wheat, Three-Nine and Dazhou variants name other qu.
Under-the-beam method wine (當梁法酒)The jar stands under the roof beam. On the 3rd of the 3rd month before sunrise, 3 dou 3 sheng each of water, dry qu powder and double-steamed millet go in together; 6 dou of millet on the 6th and 9 dou on the 9th, then any amount until full. Taking wine is called "stealing wine", and each dan taken out is replaced by a dan of cooked millet.
Non-glutinous rice method wine (秔米法酒)3 dou 3 sheng each of well water drawn at dawn, sieved qu powder and rice, then additions of 6 dou 6 sheng, 1 dan 3 dou 2 sheng and 2 dan 6 dou 4 sheng at seven-day steps (the Siku edition words the steps differently). Glutinous rice is better. Mud-sealed, it clears in 7 days.
Shijing 7th-of-7th method wine (《食經》七月七日作法酒方)1 dan of qu made as "warmed cakes" on a bamboo lattice inside a mud-sealed jar for 14 days, sun-dried and returned; 1 dan of grain yields 3 dan of wine.
Roasted-wheat qu method wine (又法酒方)1 dan each of roasted-wheat qu powder, boiled water and millet, kneaded together. Water is drawn on the 2nd of the 2nd month; additions every 10 days at first, then every 8 or 6 days, always on even days, finished within the 2nd month.
Three-Nine wine (三九酒)On the 3rd of the 3rd month, 9 dou each of water, grain and roasted qu powder mixed at once; additions after 9 days, then 5, then 3, always on odd days, finished within the 3rd month.
Dazhou white qu and mulberry-fall wine (大州白墮麴, 作桑落酒法)Qu: 3 dan of grain, 2 steamed and 1 raw, with a mulberry, cocklebur and mugwort decoction; 3,600 pestle strokes at noon; cakes on and under 2 cun of wheat straw, wiped with wet hands on day 7, sun-dried on day 28. 10 jin of qu ferments 1.5 dan of grain. Wine: 1 dou qu powder, 2 dou cooked grain and 1 dou boiled water; three additions only.
Safety
The text says the rice, bran, slops, steamed grain and cooked rice must not be eaten by people, dogs or rats, and in the under-the-beam wine the bran and slops are poured into a pit so dogs and rats cannot eat them. Grain must be washed until the water runs clear, or the wine turns black. In the roasted-wheat and Three-Nine wines, water is boiled in advance, dogs and rats are kept away, and 5 sheng of the water washes the hands and swirls the jar after each addition. The Dazhou qu variant uses a cocklebur decoction. Cocklebur is poisonous: eating its seeds and seedlings has been linked to deaths in people, including an outbreak in which seedlings were eaten as a main meal during a food shortage [gurley2010]. We found no test showing that boiling makes this leaf water safe, so do not make that qu with cocklebur; the recipe is recorded as history. A 2025 review of Chinese rice wine names ethyl carbamate, a potential carcinogen that forms from ethanol and nitrogen compounds during fermentation and storage, and biogenic amines as its main safety concerns; it speaks of rice wine in general, not of this recipe.
Qimin Yaoshu chapter 67 (法酒), compiled by Jia Sixie in the 6th century. It also gives a cure for wine turning sour (治酒酢法): for a wine of 10 dan of grain, 3 sheng of wheat roasted black is packed hard in a double bag of red silk and set on the jar bottom; after 14 days the wine comes back. Wikipedia dates the book to 544 CE on one account and to 533–544 CE on another.
