Can you still drink baijiu if its packaging is moldy?

In general, whether liquor can still be consumed after its packaging has developed mold depends on the specific condition of the mold growth and whether the liquor itself has been affected. If in doubt, it is recommended to consult a professional or simply discard it. The detailed analysis is as follows:

If only the outer surface of the packaging shows slight mold and there is no penetration into the interior, and if the bottle cap is well sealed without damage, and upon opening, the liquor appears clear and transparent, with no unusual odor or floating particles, then the liquor is likely uncontaminated. After thoroughly cleaning the exterior of the packaging, it should be safe to consume. This situation typically results from storing the liquor in a damp environment, which causes mold on the packaging but does not affect the quality of the liquor itself.

If the mold covers a large area and has penetrated into the inner packaging, or if the bottle cap is poorly sealed or damaged, and upon opening, the liquor appears cloudy, has an off smell, or contains絮状物 (flocculent substances), this indicates that the liquor has been contaminated by mold and should not be consumed. Drinking contaminated liquor may cause gastrointestinal discomfort and pose risks to health.

Liquor should be stored in a dry, well-ventilated, and cool environment to prevent moisture-related mold growth on packaging. Once mold is detected on the packaging, carefully inspect the condition of the liquor. When uncertain, do not consume it—prioritize food safety.
