Bottled Water Shelf Life

How long does water last? Water is the most abundant compound on Earth and it is essential to every form of life. All sources recommend that people drink 8 glasses each and every day. Because of its relatively low cost and proven health benefits, water is one of the most popular beverages in the world. We drink it from fountains, streams and bottles. Since the U.S. Food and Drug Administration (FDA) does not require a shelf life for bottled water, the actual shelf life of water is indefinite! Because of this, you will probably not find any sell by, use by or best by dates on your bottle of water. Because of this, many people ask does water go bad? It really does not go bad on its own, but packaging and other environmental factors can actually cause water to go bad. So, the shelf life of water depends on the preparation method (not all water is created equal) and how it was stored. So, how long does water last? When properly stored, the shelf life of bottled water is:

(Unopened) Pantry Refrigerator
Bottled Water lasts for 2+ Years 2+ Years
Flavored Water lasts for 9 Months 9 Months
Vitamin Water lasts for 9 Months 9 Months
Sparkling Water lasts for 1+ Years 1+ Years
(Opened) Pantry Refrigerator
Sparking Water lasts for 2-3 Hours 2-3 Days
Bottled Water lasts for 2-3 Hours 3-5 Days




Freezing bottled water for consumption is not recommended because of the chemicals contained in the bottle. Freezing and boiling temperatures break down the chemicals in plastic bottles which can then leak into the liquid. You can freeze and re-freeze them (but NOT sparkling water) for use in a cooler or ice chest – but do not drink them when thawed (see further notes below).
Of course, all food and drink products last for a shorter period of time if they are not stored properly. But remember, UN-like a lot of other drinks, it does not usually have a sell by date because water has an indefinite expiration date. According to Arrowhead (a leading bottler of Spring water) their bottles have a 2 year shelf life and the best before date recommended for best taste is located directly after the letters “BB” [1].

How to tell if water is bad, rotten or spoiled?

Practicing proper hygiene and food safety discipline will help prevent food borne illness. Although not a perfect test, your senses are usually the most reliable instruments to tell if your water has gone bad. Some common traits of contaminated water are cloudiness and a strange taste or smell. But, it is often your sense of taste that can tell the difference – which by the time it reaches that sense, all you can do is spit it out! If there is a chemical taste to your bottled water, it is not healthy (see below). There are, of course, certain health risks associated with spoiled drinks, so always remember to practice food safety and enjoy your water prior to its eat by date.

How to store water to extend its shelf life?

Proper food storage is the key to extending the expiration date of food and drink. Store water in a cool dark place away from cleaning products, gasoline, paint thinner and other toxic or odorous materials. Especially now that bottles have become greener (new lighter & thinner material). You can help water stay fresh longer by storing it in your refrigerator immediately after use. Never leave bottled water in direct sunlight or even inside your car all day on a hot sunny day. Chemicals from the plastic container will heat and leak into the water. Drinking these bottles that have been left in the sun have been directly linked to breast cancer in women and studies now show links to other types of cancer in both men and women. Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste.
