- If you stick a bottle of beer in the freezer and forget about it for
- a while, but not too long, it will be extremely cold (10 deg F?) but not
- frozen when you take it out.
-
- If you've timed it right, you can pop the top off the bottle and watch
- as the beer flash-freezes solid in a matter of a seconds. The first time
- I did it was by mistake and I only noticed when I tipped the bottle to
- my lips and nothing came out.
-
- I assume that the pressure in the capped beer bottle depresses the
- freezing point of beer the same way that the freezing point of water drops
- with increased pressure. When the bottle is uncapped, pressure returns to
- normal, the beer finds itself supercooled, and freezes in a hurry, starting
- at some tiny bubble maybe.
-
- My question for the net:
-
- Why does the WHOLE beer freeze solid? If the beer is only, say, 20 deg F
- below freezing, how can it absorb all the heat from the freezing ice? To
- rephrase, a beer-sized block of ice would drop a beer-sized glass
- of water a lot more than 20 deg F before melting. Shouldn't the inverse
- apply here?
-
- Does something weird happen to the specific heat of water below its
- normal freezing point? Does beer not freeze the same way that water
- does?
-
- Or should I just drink my beer at refrigerator temperatures since it tastes
- better that way anyway?
