How to store mineral water?
Store sealed bottles of mineral water at room temperature or cooler, out of direct sunlight and away from solvents and chemicals. The International Bottled Water Association gives these conditions, and says the FDA has set no limit on the shelf life of bottled water. Dates on bottles are mostly lot codes for stock rotation.

How should you store mineral water?
Keep it at room temperature or cooler, out of direct sunlight, and away from solvents, fuels and household chemicals. That is the guidance on the International Bottled Water Association (IBWA) storage page. A cupboard, pantry or cool basement shelf works; a hot garage, a car in summer or a sunny windowsill does not.
Why does sunlight and heat matter?
IBWA says prolonged sun or heat can occasionally encourage algae or mold growth in a bottle, though it describes this as not a general public health concern. Cool, shaded storage simply keeps the water fresher.
Why keep it away from chemicals?
Plastic bottles are slightly permeable. IBWA explains that vapors from paint thinner, gasoline or cleaners can affect the taste and smell of the water. Store bottles away from them, and away from strong-smelling food too.
Does mineral water expire?
IBWA quotes the FDA as determining that there is no limit to the shelf life of bottled water, so it does not require an expiration date. Some companies print date-based lot codes, which mainly help retailers rotate stock. A printed date is therefore best read as a quality guide, not a safety cut-off. If a sealed bottle smells or tastes odd, do not drink it.
How to store sparkling vs still mineral water
- Keep both sealed until you need them, standing up or lying down.
- Do not freeze sealed glass or fizzy bottles; the contents expand and can burst the container.
- Chill what you plan to drink in the fridge and keep the rest cool.
What about an open bottle?
We found no official time limit for an opened bottle. As general practice, recap it, keep it cool and drink it within a day or two. Do not top it up with other water, and do not drink straight from a bottle you plan to keep for days, because mouth bacteria can grow in it.
How to store a stock at home
- Rotate: put newer cases behind older ones.
- Keep cases off a concrete floor if damp.
- For emergencies, IBWA mentions the US Department of Homeland Security suggestion of at least one gallon per person per day for drinking and sanitation; needs vary.

How long can you store mineral water?
IBWA says the FDA has set no limit on the shelf life of bottled water, so a sealed bottle stored cool and shaded can be kept. Quality, not safety, is what changes over time.
Can mineral water be stored in the sun?
It is better not to. IBWA says prolonged sun or heat can occasionally allow algae or mold to grow, so keep it in a shaded, cool spot.
Should mineral water be kept in the fridge?
Not required. Room temperature or cooler is fine for unopened bottles; chill them only for drinking.
