A recent online post claimed that a bottle of NONGFU SPRING natural mineral water produced in 2017, after being stored for nine years, developed white flocculent substances inside the container. Regarding this matter, there has been no official response from NONGFU SPRING so far.
Customer service representatives of NONGFU SPRING informed Sina Finance that mineral water contains trace amounts of minerals, and the observed white flocculent material results from the precipitation of mineral components. The customer service clarified that the standard shelf life for mineral water is typically two years. Water stored for nine years has significantly exceeded its expiration date and should not be consumed.
