Spring water's shelf life depends on several factors, primarily whether it's unopened and how it's stored.
Unopened Spring Water
- Up to one year: For emergency preparedness, it's recommended to replace spring water stored at room temperature and out of direct sunlight after no more than one year (Source 1).
- Up to two years: Many bottled water companies suggest a two-year expiration date for unopened bottles, though the exact shelf life varies by brand. For example, Fiji water may last two years, while Nestle Pure Life may have a shorter shelf life (Sources 7, 8).
- Indefinitely (ideally): Some sources claim unopened bottled water, especially in glass, can last indefinitely if properly produced and stored (Source 6). However, this is an ideal scenario, and it's prudent to follow manufacturer recommendations.
Opened Spring Water
Once opened, the water's shelf life significantly decreases due to potential contamination. It's recommended to consume opened spring water within four to six days (Source 3). Leaving an open bottle unrefrigerated may lead to bacterial growth and spoilage within a few days (Source 10).
Storage Recommendations for Longer Shelf Life
- Store at room temperature: Avoid extreme temperatures.
- Avoid direct sunlight: UV light can degrade water quality.
- Use appropriate containers: Glass is generally considered better than plastic for long-term storage.
- Secure lids tightly: Prevent contamination from dust, insects, or airborne particles.
Remember, even if the water remains clear and odorless after a significant period, it's best to prioritize safety and follow the suggested shelf life guidelines.
