Mountain Dew is a popular soft drink that has been a staple in the beverage world since the 1940s. While it does not have a traditional expiration date, consumers often wonder about its shelf life. The best-by dates on Mountain Dew indicate the manufacturer's estimate of how long the product will remain at its peak quality. The shelf life of Mountain Dew varies depending on storage conditions and packaging. Unopened cans and bottles, when stored properly, can maintain their quality for 6-9 months past their best-by date. Diet Mountain Dew, in particular, may have a shorter shelf life due to the use of artificial sweeteners, which can go bad within a few months. However, even after the best-by date, Mountain Dew is generally safe to consume, although the taste and effervescence may change.

What You'll Learn
Diet Mountain Dew's artificial sweetener can go bad after a few months
While Mountain Dew does not expire in the traditional sense, its best-by date is an estimate of how long the product will remain at its peak quality in terms of taste and fizz. After this date, the taste and effervescence of the drink may begin to change, but it is not unsafe to consume. The shelf life of Mountain Dew also varies depending on storage conditions and packaging.
Unopened cans and bottles, when stored properly in a cool, dry place away from direct sunlight, can maintain their quality for 6-9 months past their best-by date. However, once opened, it is recommended to consume the drink within a few days, as exposure to air accelerates the decline in quality. While it is rare, Mountain Dew can go bad, especially if the container is damaged or improperly stored. Signs of spoilage include an off smell, an unusual taste, or visible contamination. If you notice any of these signs, it is best to discard the beverage.
Diet Mountain Dew, in particular, has a shorter shelf life due to its artificial sweetener, which can go bad after a few months. Regular Mountain Dew cans can keep their flavor for up to nine months after the expiration date, but diet soda will only retain its flavor for up to three months. One source mentions that diet soda will last for less than a year.
It is important to note that consuming expired Diet Mountain Dew is not dangerous, but the taste may be affected. Some people have reported drinking Diet Mountain Dew that expired a few months ago, and while it did not make them sick, the taste was described as "terrible" or "pretty gross." Therefore, while Diet Mountain Dew's artificial sweetener can go bad after a few months, it is still safe to consume, although the taste may not be as enjoyable.

Unopened cans can last 6-9 months past the best-by date
While Mountain Dew doesn't expire in the traditional sense, it's important to pay attention to the best-by date and storage conditions to ensure you enjoy your beverage at its best. Unopened cans of Diet Mountain Dew can last 6-9 months past the best-by date when stored properly. This means keeping the cans in a cool, dry place away from direct sunlight.
The best-by dates on food and beverage items indicate the manufacturer's estimate of how long the product will remain at its peak quality. After this date, the taste and effervescence of Mountain Dew may begin to change, but it does not become unsafe to consume. However, it's important to note that diet soda doesn't last as long as regular soda due to the artificial sweetener, which can go bad within a few months.
One source suggests that unopened cans of Mountain Dew can maintain their quality for up to a year past the best-by date, especially when stored in a cool, dark place. However, the taste and carbonation may start to decline, and the longer the soda is past its best-by date, the more noticeable these changes may become.
While it may be safe to consume Diet Mountain Dew past its best-by date, it's important to inspect the cans for any signs of damage or improper storage. If the can has been compromised in any way, it's best to discard the beverage. Additionally, always trust your senses; if the soda smells or tastes unusual, it's best to discard it.
Overall, while unopened cans of Diet Mountain Dew can last 6-9 months past the best-by date, it's important to manage your expectations regarding taste and quality. The closer to the best-by date you consume the beverage, the better your experience will likely be.

Taste and carbonation will eventually trail off
While Diet Mountain Dew does not expire in the traditional sense, its taste and carbonation will eventually trail off. This means that even if you consume it past its best-by date, it will not taste as good as a fresh can and may even taste terrible, depending on your view of diet soda.
The best-by dates on food and beverage items, including Mountain Dew, are not hard-and-fast expiration dates. Instead, they indicate the manufacturer's estimate of how long the product will remain at its peak quality. After this date, the taste and fizz of Mountain Dew may start to change, but it is still safe to consume. Unopened cans and bottles, when stored properly in a cool, dry place away from direct sunlight, can maintain their quality for 6-9 months past their best-by date.
However, it's important to note that diet soda doesn't last as long as regular soda. The artificial sweetener in diet soda can go bad within a few months, causing the drink to taste strange. One source suggests that diet soda will only keep its flavour for up to three months after the expiration date, while regular soda can last for up to nine months.
Once a can of Mountain Dew is opened, it is recommended to consume it within a few days to enjoy its best taste and fizz. Exposure to air accelerates the decline in quality, and while rare, it is possible for Mountain Dew to go bad, especially if the container is damaged or improperly stored. Signs of spoilage include an off smell, an unusual taste, or visible contamination. If you notice any of these signs, it's best to discard the beverage.

It won't hurt you, but it may taste terrible
While Mountain Dew does not expire in the traditional sense, it's important to note that its shelf life can vary depending on storage conditions and packaging. Unopened cans and bottles, when stored properly in a cool, dry place away from direct sunlight, can maintain their quality for 6-9 months past their best-by date. On the other hand, once a can or bottle of Mountain Dew is opened, it is recommended to consume it within a few days to enjoy its optimal taste and fizz. This is because exposure to air accelerates the decline in quality.
It's worth mentioning that while rare, Mountain Dew can go bad, especially if the container is damaged or improperly stored. Signs of spoilage include an unusual odour, an odd taste, or visible signs of contamination. If you encounter any of these indicators, it's best to discard the beverage. However, consuming expired Mountain Dew is not necessarily harmful. One source mentions drinking a can of Mountain Dew that expired 14 years ago without experiencing any negative health consequences.
Although drinking expired Mountain Dew may not cause harm, it might not be a pleasant experience. The taste and carbonation of the beverage will likely deteriorate over time, resulting in a less enjoyable drinking experience. The artificial sweetener in diet soda can go bad after a few months, affecting the flavour significantly. Thus, while expired Mountain Dew won't hurt you, it may taste terrible or significantly different from how it should, especially if it is diet soda.
Some people have reported drinking Mountain Dew that is several years past its expiration date without any issues. However, it is important to exercise caution and assess the condition of the can or bottle before consumption. Check for signs of damage, such as pinholes or unexpected leaks, and be aware that the taste may have changed. If the beverage has an unpleasant odour or taste, it is best to discard it.
In conclusion, while expired Mountain Dew is unlikely to cause harm, it may not taste as intended. The artificial sweetener in diet soda can deteriorate, affecting the flavour. Proper storage can extend the shelf life of unopened cans and bottles, but once opened, it is best to consume the beverage within a few days to avoid a decline in quality. Always check for signs of spoilage and use your best judgment before consuming any beverage past its expiration date.

Proper storage can ensure you enjoy Mountain Dew at its best
The best way to store unopened cans or bottles of Mountain Dew is in a cool, dry place away from direct sunlight. When stored this way, they can maintain their quality for up to 9 months past the best-by date. On the other hand, once a bottle or can of Mountain Dew is opened, it is recommended to consume it within a few days to enjoy its optimal taste and fizz. Exposure to air accelerates the decline in quality, and the beverage may go bad if left open for too long.
It is important to note that the artificial sweetener in diet soda can go bad within a few months, so it is best to consume diet Mountain Dew sooner rather than later. Additionally, always check for signs of spoilage before consuming, such as an unusual smell, taste, or visible contamination. If any of these signs are present, discard the beverage.
To extend the freshness of Mountain Dew, some people recommend storing the unopened can in the refrigerator a day before consumption. This allows the CO2 to be reabsorbed, ensuring a better taste and carbonation level. Additionally, giving the can a gentle squeeze can help determine if it is still pressurized and safe to consume.
While Mountain Dew has a long shelf life, proper storage is key to maintaining its quality. By storing it in a cool, dry place and consuming it within a reasonable time frame, you can ensure that you enjoy Mountain Dew at its best.
