I bought these beers at the brewery at the end of October 2016. Box says that they were canned in early Oct 2016. I have had them stored in my house at room temperature since that time. Went to go put them in the fridge for tonight and felt moisture on the box. When I opened the box all 6 of the cans were similar to this except for one on which the can was actually partially open. I poured that one out and it smelled bad and the color was very dark. The other 5 don't seem to have any actual leaks but perhaps residue from the one that had opened.

 

I'm not going to try to drink them (as much as I would like to because I cannot get more of them without going back to South Carolina) but was just curious if anyone had any idea what would have caused this to happen. The style of beer is a sour if that would make any difference.

 

 

 

Don't drink them. They'll be bad also.

I'm a beer novice, but a chemist by training. The alcohol is produced by the fermentation of yeast, which produces carbon dioxide gas, the culprit of the expanding/burst cans. I believe that in the beer making process, they usually measure/know when this process stops and that is when it is bottled. Sounds like either the brewery that you got these from haven't quite got their fermentation times down or there was a processing error that led to too much yeast in the beer. Either way, I would call the brewery and inquire about anyone else reporting issues. Who knows? They might just send you some more beer!

You might be onto something. Go Bob and Doug McKenzie on them.

 

Sometimes changes in heat and humidity within a house will cause that. I've had collectible pop cans that burst after about 10 years from the temp/humidity changes in the closet where it was stored. (Still have 2 intact and 1 empty from the 6-pack — Hatfield and McCoy Family Reunion Coke cans from 2003)

I've had it happen also. I also have a full six pack of who-dey (hudepohl) beer from 1981 that is intact with no issues.

They are probably safe, but may not taste their best. I would try them.

 

I'm assuming they are bottle conditioned. Which means they are allowed to carbonate naturally in the container as opposed to already being carbonated when put into the container.

 

Chill one and open it over the sink or outside, they are under higher than normal pressure.

Different styles have different shelf lives, but I'm not sure what it is for a sour. I just know that you wouldn't want to keep an IPA that long.

They look filthy, Stay away from them.

Thanks for the replies. I tossed the cans, not worth getting sick over, but I've held on to some beers for some time before and never had this type of issue. Normally they are bottles, maybe that makes a difference.

What beer is it?

 

I've got hundreds of beers in a cellar and a beer fridge. I've never saw this.

Meh...what's a little botulism gonna hurt?!

ALWAYS stay away from swollen cans of any kind. Something bad has happened inside that can that will probably make you ill and possibly kill you.
