Unopened bottled water has a relatively long shelf life. The actual shelf life of bottled water varies depending on factors such as the type of plastic bottle used, the storage conditions, and the source of the water. Generally, bottled water can last up to two years when stored in a cool, dry, and dark place away from direct sunlight and extreme temperatures. 

The expiration date on the bottle indicates the period within which the water is likely to retain its quality and freshness. The Food and Drug Administration (FDA) requires all bottled water to have an expiration date. The date is usually printed on the label, near the brand name, and often coded with a series of numbers and letters. 

It is important to note that the expiration date is not an indicator of the safety of the water. Bottled water does not expire or go bad in the same way that food items do. Instead, the expiration date is an indication of the time during which the water is likely to retain its freshness, taste, and quality. 

The taste and quality of bottled water may change over time due to exposure to air and light, which can affect the level of dissolved oxygen and carbon dioxide in the water. Over time, the plastic bottle can also release chemicals into the water, affecting the taste and quality. 

Once you open a bottle of water, the shelf life reduces drastically. After opening, you should consume the water within a few days, and you should always store it in the refrigerator. Storing an open bottle of water at room temperature can promote the growth of bacteria, which can cause health problems. 

If you are unsure about the freshness of bottled water, you can use your senses to assess its quality. Smell the water to check for any unusual or off-putting odors. Taste the water to see if it tastes fresh and clean or if it has a strange taste. Look for any visible signs of contamination, such as sediment or particles in the water. 

It is also essential to store bottled water properly to ensure its freshness and quality. Avoid storing the bottles in direct sunlight, near sources of heat, or in places with high humidity. It is also important to keep the bottles away from chemicals and cleaning products that can contaminate the water. 

In conclusion, unopened bottled water can last up to two years when stored in the proper conditions. The expiration date on the bottle is an indication of the time during which the water is likely to retain its freshness, taste, and quality. Once you open a bottle of water, you should consume it within a few days and store it in the refrigerator. Always use your senses to assess the quality of bottled water before drinking it, and store it properly to ensure its freshness and quality.
