Bottled Water – indefinitely shelf live under optimal conditions The FDA has not established a shelf life for bottled water. In the United States bottled water’s shelf life is date stamped for two years. This acts as a SKU number and is mainly for stock rotation purposes. It does not imply that the product is compromised after that date. As long as bottled water is packaged in accordance with FDA processing and good manufacturing practices, 21 CFR, Part 129, and is meeting the FDA quality standard provisions as outlined in 21 CFR, Part 165, the product’s shelf life should remain intact for an indefinite period of time.
Properly stored bottled water has indefinitely shelf live. However, long-term storage of bottled water may result in aesthetic defects, such as off-odor and taste. IBWA advises consumers to store bottled water in an unopened container at room temperature (or cooler), out of direct sunlight and away from solvents and chemicals such as gasoline, paint thinners and dry cleaning chemicals.
