Does Prosecco Go Bad? If you're storing your bottles of prosecco in a cool and dark environment you can expect it to last for up to two years unopened. Prosecco doesn't normally go “bad” but rather it starts to lose its unique flavor profile as well as its carbonation if you're storing the sparkling type.

Is there a date on prosecco?

There isn't an expiring date for Prosecco, but t is definitely better to drink it within couple of years. It's definitely important to store it at the right temperature and at the right conditions, therefore if you are not able to guarantee a certain storage level, I would suggest you not to go over 2 years.

Can you get sick from old prosecco?

Old champagne (or any sparkling wine for that matter) will not make you sick (unless of course, you overindulge). If you are concerned about the quality of an older wine, assess it just as you would a container of milk you've had opened a few days in your refrigerator.
