Tag: Bottled water shelf life

According to the FDA, commercially bottled water that is properly produced and unopened has an indefinite shelf life. This core principle applies to answering the question, "how long is Mountain Valley water good for?", though its packaging and storage conditions play a far more critical role in preserving its quality over time.

Technically, pure water never expires, but the plastic bottle it comes in can degrade over time. Most bottled water companies print a 'best by' date, typically two years from production, to ensure optimal taste and quality, though the water may remain safe far beyond that if stored correctly. However, improper storage can lead to an undesirable taste or even potential contamination.

Flow Hydration officially suggests consuming their alkaline spring water within 24 months for the highest quality and best taste. The actual length of time **how long is Flow water good for** depends on whether the container is sealed or opened, and how it is stored.
