Is it okay to drink 5 month old Dr.Pepper?

According to the Dr.Pepper website, “For the best flavor, enjoy this product by the date on the packaging.” The date on the packaging is typically a “Best By” date, which means that the product is still safe to consume after that date, but the quality may not be as good. After 5 months, the flavor of Dr.Pepper may be flat or off, and the carbonation may be gone. Additionally, there is a slight chance that the drink could have become contaminated with bacteria, which could make you sick.

If you have a can of Dr.Pepper that is 5 months old, it is best to throw it away and get a new one.
