If stored properly and unopened, energy drinks generally stay at their best quality for approximately 6 to 9 months after the date indicated on the package when stored at room temperature, although they can generally be safely drunk after that. However, if an energy drink is open and not in the refrigerator, we recommend that you discard it. Opened liquid containers need refrigeration to maintain their freshness, so an energy drink that has been open and at room temperature for more than a day should be thrown away. Like most ready-to-drink energy drinks, Monster cans have an expiration date of between 18 and 24 months from the date of manufacture.
This depends on whether you prefer it cold or at room temperature. It doesn't require refrigeration unless you enjoy the drink cold. If you have opened it, it is best to store it in the fridge and consume it within 4 days to reduce the chances of it spoiling. The drinks will appeal to you if you want to increase your energy without the bloating that you can associate with the typical energy drink.
While energy drink companies love to market their drinks as practically infinite energy drinks, these sugar-loaded beverages usually peak for 2 to 3 hours at most. Energy drinks are a popular and somewhat controversial source of caffeine and energy, and are often synonymous with beverages like Red Bull and Monster. At the end of the day, there's (usually) nothing wrong with drinking an energy drink for at least a couple of months after the expiration date printed on the can. To ensure that the drink stays in good condition, always store it in a dark and cool place to avoid exposure to heat and sunlight, which are responsible for the energy drink to go bad.
Next, you can tell if a single can of energy drink is expired or has broken down, if the can looks “swollen” or looks like it's expanded. Each can contains 160 mg of caffeine instead of the standard 180 mg, and contains 90 calories instead of the 150 to 180 calories found in most energy drink cans. The easiest way to tell if an energy drink is no longer good to consume is if it has had an expiration date of three years or more in the past. It also adds a vitamin C content, which adds a healthy antioxidant component that you might not find in other energy drinks.
Even so, many people drink an energy drink in the hope of getting a big energy boost, especially if they don't drink coffee. If you have stored your drinks properly (in a cool, dark place that is not exposed to extreme temperatures), the drink will likely last 6 to 9 months longer than the expiration date. Your energy drink will taste its best within the first 6 to 9 months of production, that's for sure. Right from the start, you should know that there's rarely anything wrong with drinking energy drinks, even a couple of months after the expiration date printed on the can.
Keep in mind that it's not as important to include the expiration date on these energy drink cans on the menu as it is for products such as beef, chicken, fish, cheese and dairy products.
