That's right...cans and GLASS bottles will keep longer. Plastic bottles apparently allow some exchange of air....because the plastic bottles get "squishy" when they are old. I think the C02 leaks out!
Unopened soda bottles retain their carbonation the longest, exceeding the printed sell-by date on their labels. When stored under optimal conditions, unopened bottles of soda can stay fizzy for up to 9 months beyond this marked date. For a long shelf life, store plastic bottles of soda in a cool, dark place. While soda won't typically be spoiled beyond the expiration date, it is likely to be noticeably flat after 9 months of pantry storage beyond the sell-by date even under optimal conditions.
Some manufacturers stamp a sell-by date, while others stamp a born-on date. Some expiration dates are easy to read, while others appear as complex codes that need to be deciphered and can easily be misinterpreted.
Poor storage conditions and extended storage can easily leave you with flat soda. Carbon dioxide eventually escapes from an unopened bottle of soda and this is unpreventable.
Here is an extra note about DIET soda:
While the carbonation in diet sodas doesn't dissipate any quicker, saving diet sodas beyond the recommended nine months can yield an unpalatable glass of soda. Artificial sweeteners break down over time and impart a bad taste, making it important to drink these products closer to the sell-by date for the best taste as well as good carbonation. While it's still safe to drink diet soda up to nine months after its sell-by date, if your diet soda has an undesirable taste, discard it.
BTW: soda or beer from a can tastes much fizzier than the stuff that comes out of a bottle. Manufacturers dissolve the same volume of carbon dioxide into their plastic- and aluminum-bound products, but polyethylene terephthalate plastic is somewhat more CO2-permeable than aluminum. That means the fizz will leak out of a plastic bottle of Coke at a higher rate than it would from a can.
If the soda gets warm while still in the can or bottle, the gas will leave the soda and enter the head space—that's the area between the soda and the cap used to regulate pressure—and release into the air the moment you open the container. Coca-Cola is slightly more carbonated than its diet counterpart. Ginger ale has almost twice the carbonation of most colas.
Please remember, the "Sell By" date is NOT an "expiration" date. It merely means that the product is at its best before that date, and may not be very good after that date.
We have used heavy cream nearly a year after the sell by date. It sat in the frig all that time, and was still good!
I have bought soda (Diet Pepsi, mostly) from the little store on the corner by my place. They often stock drinks that are past the expiration date printed on the cap, and the drink is flat. How could a carbonated drink lose its fizz when it's in an airtight bottle? (I had thought at first that the expiration date was no big deal--it wouldn't be a health hazard,
its already a health hazard!

I feel like a wine snob now, but I'll check each bottle to make sure it is before the expiration date before I buy it.
A case of soda in aluminum cans that was sitting on my kitchen floor, ate through the cans and spilled soda all over everything. So the sell by date does mean something.
Those cans were not just a few weeks past sell by date, though.

Now that's a lovely thing to know. Ate through the aluminum????
I won't say never, but I rarely drink soda. Sounds as if that's a good move.
Time flies as proven by the expiration dates on my spices!!
Oh my goodness, I just cleaned out and sorted the shelf in my kitchen that had a zillion containers of various sizes and brands containing various spices! Lol!! It's like a time warp in there! A virtual history museum!
"But wait! What? Wasn't 2011 just a couple of of years ago?" (it was FIVE!) "Oh I remember 2009... that's the year we..." etc. etc.
I actually found an unopened bottle of hot sauce from 2004! Okay, now that's scary!
I didn't know spices could go bad. I have some spices that I bought 10 years ago that are still fine to use.
