I brewed Stone Ruination. After two weeks of being bottles the beer foams out for about 2 seconds. not a huge loss but still messy.

They were fine a week ago, good carb, didn't foam out.

Got home from vacation last night, threw one in the fridge, popped her open about 2 hours later. Foams.

Will the foaming subside when chilled for 24+ hours?

How to proceed?

Will foaming get worse?
 
My (not so vast) experience with this is that it's probably a little over carbonated. It will only get worse (probably not much) over time, but luckily IPAs demand to be drank ASAP anyway. I had an English Mild that did that, but much worse; lost about half the bomber every time. Come to think of it, that one may have been infected...
 
Actually, foaming is often a sign that the beer is not yet fully carbed. Sounds counterintuitive, but is true. Since you are only at two weeks in, I'd lean towards this being the case.

You have CO2 in the bottle, but it's not yet fully dissolved in solution.

Baseline for carbing is three weeks at 70 degrees. Bigger beers or lower temps require more time.

Wait another week, then throw a couple in the fridge for a day or two. If still foaming, wait a little longer.

If STILL foaming, you may have picked up a wild yeast.

All of the above is assuming your final gravity was stable, and that you used the right amount of priming sugar, and that you mixed said sugar properly.
 
Makes sense. Like I said, not so vast experience with it. I guess that's a good thing? :)
 
Also, throwing it in the fridge for 48 hours (or a week or two) helps. I never understood this but learned it from the forums here. CO2 mixes into solution better in colder liquids, and I've seen proof of that now in my own processes. But if this doesn't help, see the above posts :) Or maybe the posts below this one too...
 
I have found that carbing to style using one of the online priming sugar calculators causes me to overcarb my beer (even if I use the low end of the spectrum). Most kits send 5oz. of priming sugar and I just used the 5oz when I first started. I thought I was improving my beer by using a priming calculator. For example, I recall the priming calculator calling for 8.9oz of sugar when I usually use 5oz. Well... every bottle in the batch just about explodes out of the bottle. I have yet to figure it out totally. I live at 7200 feet which may play a part. I usually just calculate the amount of priming sugar using the lowest end of the spectrum, then subtract off 1-2 oz.
 
I had that on a batch and found chilling it for a while, (several hours) seemed to help. Probably overcarbonated, not a huge problem other than loss of beer, and mess :(
 
co2 does mix better at lower temps. I worked bottling soft drinks and we carbed and filled at about 35 degrees. If the temp would go up to over 45 the co2 volumes would drop. The co2 holds in suspension in liquid at a lower temp. At 2 hours of chilling the beer probably was still to warm for the volumes to be up and the foaming would occurr because of that.
 
Ive had foam one or two times maybe because of not being chilled long enough.Almost every time i quick chill one,no foam. I often pull one and just quick chill it. Small Ice bath in a 1/2 gallon jar of water/ice and stir or freezer usually. I have overcabonated due to what a recipe stated to prime which was too much,so i just put them all in the fridge-they were slow foamers.What was your volume bottled and amount of priming sugar?
