If only 2 have blown then most likely it's just that those 2 bottles may not have been cleaned/sanitized properly. Still, stick them away somewhere safe for a couple of weeks an see if any more go up.

I've always gone by highest fermentation temp. Now I'm no scientist, but I really struggle to believe that the amount of c02 in a headspace wouldTheWiggman said:As slcmorro said, there's been conjecture here (and elsewhere) about the impact of priming cold conditioned beer as it will contain dissolved CO2 . From Brewersfriend:
"However, if the beer was cold crashed, or put through a diacetyl rest, or the temperature changed for some other reason... you will need to use your judgment to decide which temperature is most representative. During cold crashing, some of the CO2 in the head space will go back into the beer. If you cold crashed for a very long time this may represent a significant increase in dissolved CO2. There is a lot of online debate about this and the internet is thin on concrete answers backed by research. We are open to improving the calculator so please let us know of any sources that clarify this point"
I've sugar primed lagers from a CCed brew at ~1°C and didn't notice and extreme carbonation difference, certainly not enough for bottle bombs.
I'm leaning towards infection. Have you opened a different stubbie to see if the others are heavily primed?

Ok good I'll try that. Only 2 have blown, 1 from each batch. It's been at least 24hrs since the first blow, and I'm not sure if they happened simulataneously, as in, the explosion from one bottle blew out the next (I didn't hear anything / mustn't have been home)Blind Dog said:+1
Particularly as the others you opened did not (presumably) spew froth everywhere

Probably 99% none of the above.InterCooL said:I did so many new things in these 2 batches that I'm not even sure what to think it could be.
1. It was my first full volume BIAB (my prior perfect batch was a mini mash BIAB)
2. I used a different brand of carbonation drops (Brew Cellar)
3. It was my first time using Brewmate and coming up with my own final ingredient weights.
4. It was my first time using 10L jerry cans as fermenters.
5. First time no-chilling.
6. First time using glad wrap lids.
7. I very well may have over pitched my dry yeasts (obviously designed for 23L batches).
8 First time cold crashing
