Well, you do not have to panic. Relax and calm down; let’s learn in detail about how bad the impact can be. 

Can Beer Go Bad?

Before we talk about how much it can affect you, let’s see if beer really goes back. To keep it short, yes, beer can go bad. You will notice that there are expiring dates marked on the label or on the bottle of the beer.

Now that you know that beer can go bad, let’s talk about the impact of drinking bad beer. Does it have any threatening effect on your health? Is there anything you need to be worried about?

Let’s not ask any more scary questions. The good news is it is very unlikely to get sick by drinking bad deer. Beer does not cause food poisoning in any amount. Well, isn’t that great news? It won’t be a problem if you forget to check the expiration date before drinking beer. 

Seriously, there is no life threat in drinking bad beer, that is for sure. However, you may face some mild problems. For example, you may face a little cramping in the stomach if you drink an excessive amount of bad beer. But that does not take any severe turn. 

How Long Does Bad Beer Last?

Okay, it is great that bad beer is not going to make you sick. But how long will they last? Surely, you cannot expect to drink an eternally old bad beer and still receive no side effects, can you?

Low alcohol by volume (ABV) beers will lose their flavor after roughly 6 months if they are kept unopened on a shelf. Higher ABV beers like iambics and stouts are designed to be aged or cellar, so keeping them on the shelf for a while actually improves their flavor. Just be sure to preserve them properly.

Beer lasts less time after being opened. When beer is opened and kept in the refrigerator for a prolonged period of time, it becomes flat. Don’t be a novice if you’re going to drink a beer, is our greatest piece of advice. 

Simply complete it responsibly, of course. Don’t put it off until later. Similar to flat soda, flat beer has lost its carbonation and tastes very stale. It includes carbonation for a refreshing flavor that makes your mouth swim.

How To Stop Your Beer From Going Bad

If you want to save your beer from going bad, then you need to be careful about storing them. That is the secret. Beers do not like light. Therefore you can prevent having a beer that is light-struck by selecting dark-bottled beer and keeping it in a cold, dark location away from the sun or other sources of strong light.

Your beer is secure if they are contained in a keg or can because these containers are impregnable. Keep bottles upright with the caps on. Beer with a cap does not need to be stored on its side, unlike wine with a cork.


Let’s make it clear again. Can bad beer make you sick? The answer is a big fat no. Bad beer does not make you sick. All it does is make you feel annoyed with the smell and taste of the beer. Other than that, there are no side effects of bad beer on your health.
