Briefings

Ancient Chinese brewers in eastern China utilized red mold to ferment rice into alcohol over 5,000 years ago, followed by cloth straining to separate the liquid from grain. Microscopic residues on pottery confirm both the fermentation technique and the filtering method used at the time.

Key points

• Red mold was used as a catalyst for fermenting rice into alcohol in eastern China 5,000 years ago.
• Cloth straining was employed to separate the fermented liquid from the remaining grain.

Context

This discovery provides early evidence of sophisticated fermentation and filtration techniques in ancient China, predating known historical records by millennia.

Limitations

Evidence is limited to microscopic residues on pottery; specific locations, dates, or quantities are not documented in the source.
