What would cause a home brew to explode in a bomber bottle? Made a roasted nut brown ale. OG 1.069 FG 1.010. bottle conditioned with corn syrup and honey. It was bottled for 10 days in my back room which gets up to 70 degrees sometimes. not in the sun. it blew the top off and put a hole in my 8ft high ceiling

Any number of things, flaw in the bottle, infection causing over carbonation, temp spike, the fact that you used corn syrup and honey to prime with and didn't calculate exactly how high the sugar content of both those items were.

In fact if the last one was the case, you may have a couple of cases of bottle bombs.

I've never used anything but corn sugar or dme to prime with, and I measure by weight, so I couldn't tell you what the correct amount of corn syrup and honey to use, but how much did you use?

I'd recommend putting the rest of those guys in a rubbermaid tote, if another one blows it's lid then chill them down IMMEDIATELY, after that you can crack the lid to release excess CO2 and recap! I'd be willing to bet that they are overprimed, did you use a priming calculator like this one to calculate how much honey/corn syrup to use?

This was a month or so ago. ive had a couple of the beers and has standerd carbonation. Just that one bottle. it must of been some "sanitize" issues with that bottle... but putting a hole in my ceiling was crazy!

Revvy, i used 1/4 cup of honey and 1/4 cup corn syrup which is the first time i tried using honey as a priming agent. Too much?

if you work at an office or someplace with an IT department see if you can get ahold of a box from those canned air computer sprays. they have a pretty thick cardboard grid that separates the cans which is the perfect size for standard bottles. you may be able to get similar boxes from a liquor store, booze comes in a slightly larger configuration. that way if you get another bottle bomb it won't take out any of its brothers. and throw the whole box in a garbage bag or a rubbermaid tote as stated above.

Without more info, nobody knows.

Honey varies in fermentability, you have to dilute down a portion of your batch of honey and figure out the OG in order to know how much to use. You're also much better off measuring by weight (rather than volume) since honey can vary in density.

Corn syrup has similar issues, though a specific type of corn syrup will have much lower variability in fermentability.

What was the maximum beer temp post-fermentation? You also need to know that to figure out how much dissolved CO2 is already present.

if all other bottles have been fine, I suspect it was a one-off infection or just a flaw in the bottle. the photo sorta looks like a really thin bottle. I've broken a few commerical pop-top bottles when capping them.

Hell I had a waiter break the lip off a stella bottle 2 weeks ago opening it. Glass is like that.

+1 to this. i've had the same thing happen. you can have flawed glass no matter the thickness of it.
