Why do water bottles have a "best if used by" date?

Answer 1

B/c they add other things to it...(which is really crazy!!!)

Answer 2

Some states require all food and beverages, including bottled water, to state an expiration date on the label. Over time, the water picks up flavors from its packaging. These flavors, combined with warm storage temperatures, contribute to the "generation of musty tastes." The FDA has not established a shelf life for water, so you can store those bottles indefinitely. As long as the packaging is intact and unopened, you shouldn't worry about any type of bacteria or microorganisms growing in the water. If the bottle has been opened, however, it can grow bacteria and algae if it is not consumed within 2 weeks.

Answer 3

because just like soda water goes flat and tastes different. leave a glass of water out on the table for a day and come back the next morning and drink it.... you will taste the difference

Answer 4

I often wonder that myself. If the water is tightly seal, why does it have a expiration date on it? It's it all natural ?

Answer 5

I guess they figure you should drink it and not just stick it on the shelf and grab a coke

Answer 6

good question to ask.. i would say becuase there are additives and maybe it just wont taste as fresh if you drink it next year.

Answer 7

Answer 8
