Can You Freeze Soda?
Don’t freeze soda! Soda is mostly water, which freezes at 32°F. More importantly, remember that water (or any liquid for that matter) expands as it freezes. Therefore, the combination of the freezing water along with the pressure from the carbonation within the soda will deform the shape of the thin aluminum casing which surrounds the soda.
In fact, the can may get so out of shape that it actually bursts!
A warm soda can be placed into a freezer for a short period just before opening, but just long enough to cool if off. In about 15 or 20 minutes, the can will be cool and should then be removed from the freezer. The problem is remembering that you did this. If you do forget and leave the can in the freezer for a longer period of time – and it has not exploded – then be sure to place it into the refrigerator to completely thaw before attempting to open it.
The same holds true for soda that comes in a plastic or glass bottle instead of a can. To be safe, make it a practice not to freeze soda of any kind.
