I think he meant salting the ice around the beer. Helps the ice last longer.

I meant salting the ice around the beer, yes, because it lowers the temperature to well below freezing.

The ice does not last, however, longer. In fact, the ice melts faster, but the forced melting draws the heat out of the beer faster than just normal ice. This is the same pricipal at work in your air conditioner.

And yes, unless you are quick, you will freeze the beer — that’s the point. It’s the quickest way to cool hot beer.
