However, if the water is exposed to sunlight or heat, it can encourage the growth of bacteria and algae in the glass bottle, which can make the water unsafe to drink.

While water stored in a glass bottle may not have an expiration date like bottled water, it’s important to use your best judgment and discard the water if it looks or smells strange, or if you suspect that it may have become contaminated.

Bottled Water With The Longest Shelf Life

One brand that is known for having a longer shelf life is Blue Can Water, which uses aluminum cans instead of plastic bottles to store the water. The company claims that its water can remain safe to drink for up to 50 years if stored properly, due to the airtight seal provided by the aluminum can.

While the shelf life of bottled water can vary depending on the brand, the type of plastic used, and the storage conditions, some brands claim to have a longer shelf life than others.

For example, some manufacturers produce bottled water that is treated with a UV sterilization process, which can extend the shelf life of the water.

Additionally, some brands use a higher quality bottle that is less permeable, which can help to prevent the water from absorbing chemicals or flavors from the bottle over time.

Overall, the shelf life of bottled water can vary depending on several factors, and it’s important to check the “best by” date and store the water properly to ensure that it remains safe to drink.

How To Know Expiry Date Of Plastic Bottles

The expiry or “best by” date of a plastic bottle is typically printed on the label or the bottom of the bottle. The date is usually in the form of a month and a year, such as “06/2024,” which indicates that the bottle should be consumed by June 2024.

It’s important to note that the expiry date on a plastic bottle is not necessarily an indication of when the water will go bad or become unsafe to drink, but rather a recommendation from the manufacturer for when the water will be at its optimal quality and taste.

In many cases, water can remain safe to drink for long periods of time beyond the expiry date if stored properly.

If you are unsure of the expiry date of a plastic bottle, or if the date has worn off or is no longer legible, it’s best to err on the side of caution and assume that the water may no longer be at its optimal quality. In this case, it’s best to discard the water and purchase a fresh bottle.

How Long Does It Take For Water To Expire

Water does not expire or go bad in the same way that food can spoil, but it can become contaminated over time and therefore unsafe to drink. The shelf life of water can vary depending on several factors, such as the quality of the water, the type of container it is stored in, and the storage conditions.

In general, if water is stored properly in a clean, airtight container in a cool, dark place, it can remain safe to drink for a long period of time, often for several years.

However, if the water is exposed to heat, light, or air, it can encourage the growth of bacteria, mold, or algae, which can make the water unsafe to drink. In addition, if the container is made of low-quality plastic, it can leach chemicals into the water over time, which can also be harmful.
