Alcoholic drinks from Fujian

Hongqu jiu / Fujian laojiu (red-qu rice wine)红曲酒

Hongqu jiu is a red rice wine from Fujian made by fermenting steamed glutinous rice with hongqu, rice grown with Monascus mould. The jar stays open under cloth while the mould and yeast work, then is closed for a longer, airless fermentation; the wine can be aged for years.

At a glance

Hongqu jiu is a red rice wine from Fujian made by fermenting steamed glutinous rice with hongqu, rice grown with Monascus mould. The jar stays open under cloth while the mould and yeast work, then is closed for a longer, airless fermentation; the wine can be aged for years. Made in 6 steps over 40 days. The longest step, close the jar for the airless fermentation, takes 30 days (Yan Y 2024). Monascus purpureus and Saccharomyces cerevisiae do most of the fermenting.

What makes this one different

Shaoxing wine uses wheat qu and a yeast mother. Hongqu jiu uses red yeast rice, so Monascus colours the wine red and shares the work with the yeast. The jar is first left open under cloth, then closed.

Alcoholic drinks from Longyan, Fujian, China

The wine jar is said to sink and float again and again during brewing, which gives the wine its name. It is classed as a sweet hongqu huangjiu.

Safety

Some Monascus strains can make citrinin, and contamination by other moulds can bring other toxins, so strict food-safety standards and monitoring of safety indicators in the finished product matter. Hongqu wine carried more biogenic amines than xiaoqu wine in one study.

Hazards the sources name: Klebsiella (a main bacterial genus in one hongqu mash; the genus includes opportunistic pathogens); Citrinin, a mycotoxin some Monascus strains can make.

History and sources

Every number is labelled with how it is known. How this atlas is made

Fujian hongqu rice wine is made mainly in Fujian province with starters containing Monascus purpureus. Yu and colleagues (2025) say Wuyi hongqu has been used as a starter for more than a thousand years. The lees (hongzao) are used in Fujian cooking (Wikipedia).
