What happens when you overchill your beer and go to raise it's temp a bit with a propane torch.



(in my defense I do do this regularly when I've left beer in the freezer too long and it's too cold (bitter loses all flavour if too cold). The correct technique is to keep the flame on the can at the liquid, and keep the liquid moving so there's no localised boiling.

What I did wrong here, was try to speed up the operation, by putting the can down and blasting it with the torch upturned a bit, which makes it spit gas and gives a bigger flame, which doesn't burn as hot, but spreads out, so less concentrated heat, which engulfed the can. I think what caused this was the heat hitting the dry part of the can, if there was some foam in there, that could have boiled pretty damn quickly and the seal of the can bust.

God it was loud, my ears are still ringing.

The beer in question is going down a treat though. :)

I probably would have reached for another beer personally!

Another? Bugger-all wrong with this one! It just entered the world with a bang!  :tongue:

It was actually particularly smooth, the head was almost cream. The shock wave must have done something to it.

Ah gotcha. It was warm that one up a bit or have a room temperature one, so... And yeah, it was like Caffrey's/Worthington's Creamflow. The widget normally triggers the nitrogen expulsion, so I guess it was that effect X10.

I've got a Guinness Surger unit, which sends an ultrasonic pulse through the Guinness to trigger to the nitrogen to come out of solution, so it's totally plausible the shock wave of the can going bang did have a positive effect on the beer. I'm not going to repeat it though, my ears were ringing for an hour afterwards.

Haha I've just seen this!  I thought the photo was going to be of a hole in the ceiling!
