How long can bottled water be kept after opening?

Bottled water is a popular product in today's life. It is popular because of its convenience, especially for collective activities. However, the issue of safety is of great concern, and how long bottled water can be preserved after opening is something that many people wonder about.

How long can bottled water be stored?

While sealed water bottles may be safe to drink for up to a year, opening them will significantly shorten their shelf life. Once the bottle is exposed to air, the environment, or the elements on the hands and mouth of the drinker, the water is no longer safe.

The shelf life of unopened bottled water that has been stored properly is approximately 6 months. If the bottled water is natural, there is no need to worry about expiration, but if the water has been treated, it is best to use it within 6 months, because the carbon dioxide in the air will react with the water and make it acidic.

Therefore, 6 months is the ideal time for bottled water to maintain its quality and ensure safety for users. After this time, the water will change in quality and will not be good for human health.

Bottled water, once opened, has a maximum shelf life of 15 days, and is best consumed within 7 days. Once opened, the water inside will be exposed to air and bacteria will also enter. Therefore, if left for too long, bottled water can easily become contaminated with bacteria, viruses, etc., causing poor water quality, bad odor, and harm to health.

Bottled mineral water should be consumed as quickly as possible after opening to ensure maximum purity. If necessary, open bottles should be stored in the refrigerator to slow bacterial growth. According to shelf life experts at Still Tasty, a continuously refrigerated bottle of water can maintain its quality for four to six days after opening.

Store bottled water properly

How long bottled water lasts depends a lot on the conditions and how it is stored. If you do not store bottled water properly, the shelf life will not last up to 6 months.

Bottled water should be stored in cool places and away from direct sunlight. Heat can warm the water, making it easier for harmful chemicals in the bottle to seep into the water.

The place to store the bottle must be dry, clean, and free of stagnant water to avoid re-infection.

Read carefully the instructions for use and storage period to always use the best quality water source.
