Have you ever wondered about the expiration date on your favorite can of soda? Do soft drinks truly expire, or is it safe to consume them past the printed date? The question of whether it's safe to drink expired Diet Coke, or any expired diet soft drink, is common. While the Food and Drug Administration (FDA) doesn’t mandate expiration dates on soft drinks, understanding the guidelines and potential risks is essential. Contrary to popular belief, the date on a soft drink can or bottle isn’t a strict expiration date; beyond this date, the taste and fizziness might gradually decline, but it doesn’t necessarily render the drink unsafe. Let's delve into the factors that affect the safety and quality of expired diet soda.
Understanding Expiration Dates and "Best-By" Dates
For the most part, these dates indicate when the products retain their best quality. A best-by date will tell you when the product is at its best quality and when its peak quality ends. The date on the Diet Pepsi is next week, you'll still have three months to drink it until its quality begins to decline. If it's a can of regular Pepsi, it can last for nine months after its stamped date. Seeing a best-by date on drinks might be confusing, but the USDA assures us that any foods or drinks with this label are safe to consume, provided there's no evidence of spoilage, such as it smelling bad or having a different color or texture.
For regular soda, the “best-by” date is a general guideline for peak flavor. The primary concern with exceeding this date is the potential loss of carbonation, resulting in a flatter taste. Diet soda, on the other hand, might have a shorter “best-by” period.
How Long Does Diet Soda Last?
How long do unopened diet soft drinks last at room temperature? Properly stored, unopened diet soft drinks will generally stay at best quality for about 3-6 months after the date on the package when stored at room temperature, although they will usually remain safe to drink after that. How long do unopened diet soft drinks last in the refrigerator? Properly stored, unopened diet soft drinks will generally stay at best quality for about 3-6 months after the date on the package when stored in the fridge, although they will usually remain safe to drink after that.
Factors Affecting the Safety and Quality of Diet Soda
Several factors influence how long diet soda remains safe and palatable. These include:

Packaging
The packaging plays a crucial role here. Cans, with their airtight seal, preserve carbonation and flavor better than plastic bottles. The outside of the can is the part you should be most concerned about. A soda might taste bad if the can or bottle is rusted or damaged.
Storage Conditions
Proper storage is vital for extending the shelf life and preserving the carbonation of your favorite soft drinks. It's best to keep an open soda can in a place where the temperature is consistent. Cover the top of the can or pour it into a plastic bottle to retain the bubbles. Plastic bottles should be kept in a dark place like a pantry. Refrigeration can further extend their shelf life and maintain optimal coolness.
When it comes to storing soda in clear bottles, shielding it from bright light is crucial. This is because exposure to light can accelerate the degradation of the beverage, leading to a less enjoyable drinking experience.
- Chemical Reactions: Bright light, especially from the sun, can trigger chemical reactions in soda, altering its composition.
- Impact on Carbonation: Light exposure can facilitate the release of carbon dioxide, the component that gives soda its fizz.
- Keeping soda in clear bottles away from bright light helps maintain its flavor, carbonation, and quality for a longer period.
Ingredients
Be mindful of the type of soft drink as well, as variations like diet or zero sugar can impact shelf life. Obviously, there's no actual sugar to ferment into alcohol (just artificial sweeteners), so that can't have actually happened.
Potential Risks of Drinking Expired Diet Soda

Taste and Quality
“The quality and taste of expired soda may be severely impacted,” Schwan said. “Plus, you may have an unpleasant experience with the awful taste and lack of bubbly fizz,” she said. Because soda is basically carbonated water and sugar (or artificial sugar), unopened soda isn't likely to go bad until well after its best-by date. It might even retain the taste after a few years.
Loss of Carbonation
According to the USDA, soda loses its carbonation over time. The primary concern with exceeding this date is the potential loss of carbonation, resulting in a flatter taste.
Chemical Changes
The contents of "soda" cans is acidic because when CO2 dissolves in water it produces carbonic acid. The acid dissolves the aluminum to produce aluminum carbonate.
Packaging Integrity
The outside of the can is the part you should be most concerned about. Look for extreme dents, a puffed out or bulging appearance, or signs of rust - and if you find any, ditch it immediately, according to the experts at Does It Go Bad. The same goes for any leakage, which will open the soda up to outside bacteria. A soda might taste bad if the can or bottle is rusted or damaged. Check the color of the soda as well.
How to Determine if Diet Soda Has Gone Bad
Before opening a can or bottle of diet soda, inspect it for the following signs of spoilage:

- Damaged Packaging: Look for extreme dents, a puffed-out or bulging appearance, or signs of rust.
- Leakage: Check for any signs of leakage, which can open the soda up to outside bacteria.
- Off Odor: When it comes to guzzling down that questionable brew, you want to look for the same signs of spoilage you would in anything else: an off odor.
- Change in Color: Check the color of the soda as well. When it comes to guzzling down that questionable brew, you want to look for the same signs of spoilage you would in anything else: a change in color.
What Experts Say
“Should you be drinking it? The short answer is no,” said Schwan, an assistant professor in the College of Family and Consumer Sciences and UGA Cooperative Extension food safety specialist.
Real-World Scenarios
Have you ever seen intact, full bottles of vintage soda in an antique or vintage store, caps still on, full to the brim with colored liquid, and thought, "Gee, I wonder if it's safe to drink that 40-year-old bottle of Coke?" Ever come across old bottles or cans of a discontinued soda like Jolt Cola for sale and wondered if it would be safe to give it a try and see what all the fuss was about? Well, the answer may surprise you. That being said, we wouldn't advise you to go out and try the oldest soda you can find. But enough with the crazy old soda… what about soda that's just been sitting forgotten in the back of your pantry for a while? Can you drink that?
Recommendations for Safe Consumption
For best quality, consuming soft drinks within the “best-by” period is recommended. The key is to check for any signs of damage, leaking, or off-putting odors before consumption. The USDA recommends consuming soda within nine months of the expiration date for best quality.
