The shelf life of bottled water can vary depending on the type of water, the storage conditions, and the packaging. Generally, unopened bottles of water can last for several years without going bad, but the taste may begin to degrade over time. It is recommended to consume bottled water within two years of the bottling date for optimal taste and quality. 

When it comes to opened bottles of water, the shelf life is shorter. Once a bottle of water is opened, the risk of contamination increases. Bacteria can enter the bottle through the cap or mouthpiece and begin to multiply in the water. It is recommended to consume opened bottles of water within a few days to ensure freshness and safety. 

The storage conditions of bottled water can also affect its shelf life. Bottled water should be stored in a cool, dry place away from direct sunlight and other sources of heat. Exposure to sunlight and heat can cause the plastic to break down and release harmful chemicals into the water. It is also important to store bottled water away from chemicals or other products that may contaminate it. 

The packaging of bottled water can also impact its shelf life. Plastic bottles are the most common type of packaging for bottled water, but they can leach chemicals into the water over time. To minimize this risk, choose bottles that are made from high-quality plastic, such as PET or HDPE, and avoid reusing single-use bottles. 

It is important to note that the expiration date on bottled water refers to the quality of the water, not its safety. Bottled water is generally considered safe to drink even after the expiration date has passed, as long as the packaging is intact and the water has been stored properly. However, it is recommended to consume bottled water before the expiration date to ensure optimal taste and quality. 

In conclusion, bottled water can remain fresh for several years if stored properly and unopened. Once a bottle of water is opened, it should be consumed within a few days to ensure freshness and safety. The storage conditions and packaging of bottled water can also impact its shelf life and quality. When in doubt, it is best to consume bottled water before the expiration date to ensure optimal taste and quality.
