Frozen Beer mystery
Last Fri night, wanting to wash away the weeks woes had a couple of ales. The third one of the six pack was frozen!!! aaagh!!!! Damn, I thought, and purely in the interests of science you understand, I had to test the remaining bottles - all OK. How does a bottle IN THE MIDDLE of a six pack freeze, while the surrounding bottles are OK...

It's summer, 'down there' too, isn't it?

Which proves the Frozen Beer, to be no less than a Miracle! |

 They were all frozen and the middle was the last to thaw? |

Tom, that's a plausible explanation, but I'll have to test the hypothesis again this Fri night....just to make sure....

You will probably find that bottle had the lowest gas pressure?
See instant beer freeze on you tube Regards James

The pressure in the frozen bottle was a smidgin less than the others. The others were probably on the ragged edge of freezing, but had higher pressure, reducing the freezing point slightly. Was it frozen before you popped it?
If you want some science, you'll have to look at a T-S diagram for water..... Was the middle one the first one you popped? |

Maybe that bottle was closest to the refrigerant coil in fridge? I hate beer that cold, even in the summer. Alcohol abuse.
