Up to nine months after the expiration date, soda is considered safe to consume if the container is unopened, undamaged, and stored properly. This is owing to the large number of additives and chemicals added to carbonated beverages, which specifically extend their shelf life. Diet Coke, which has less sugar, may be consumed for up to four months after the expiration date.
There is typically no expiration date printed on sodas. Instead of expiration dates, soda firms typically include best-by dates on their cans and cartons. This date indicates how long the producer believes the unopened beverage will maintain its optimal quality.
Best-before versus Expiration Date
A best-by date indicates when the soda’s flavour is expected to diminish due to its age. A date of expiration, on the other hand, indicates a possible health risk associated with consumption. With a best-by date instead of an expiration date, it is safe to consume the soda well after the date listed on the label.
Soda Varieties and Their Expiration Dates
Coca-Cola, 7-Up, and Diet Pepsi have an unopened shelf life of six to nine months, regardless of whether they are stored in the refrigerator or the pantry. Once opened, a can of Diet Coke will last one day in either environment, whereas a bottle of Diet Pepsi would last between one and three days in a pantry and between two and five days in a refrigerator.
How to Properly Store Soda
Unopened carbonated beverages should be stored in cool, dark settings. The containers will have a longer shelf life if they are stored away from direct light and heat, and not in an area with variable temperatures.
Once the soda bottle has been opened, any leftover soda must be stored in the refrigerator. A bottle must be tightly sealed beforehand, whilst the remaining liquid in a can should be put into a separate container and the top of that container should be covered to attempt to retain the bubbles.
How to Determine When Soda Has Lost Its Flavor
Your individual discretion will determine if it is OK to consume soda that has passed its expiration date. If it is not carbonated when poured into a glass or appears watery without bubbles, do not consume it.
As the soda begins to expire, the level of carbon dioxide decreases, causing the loss of carbonation. This imparts a bland flavour but is harmless. Nonetheless, this is an indication that the beverage has passed its prime.
In addition to being flat, it will also have a terrible flavour. After the expiration date, diet sodas taste worse than ordinary sodas due to the chemical breakdown of the artificial sweeteners. In the event that you smell a foul odour, you should not consume the soda.
Soda in Food
When used in food, the soda is only as good as the ingredient with the shortest expiration date, regardless of the best-by or expiration date.
