It depends on the alcohol content, but most wine will freeze at about 15 to 20 degrees F, and it would need to stay at that temperature for a while before it freezes solidly. Alcohol�s freezing point is lower than water, but as the water content of the wine begins to freeze, it will begin to expand, and this will put a lot of pressure on the cork, which might begin to be pushed out, and on the bottle, which might crack. Don�t freeze your wine bottles.
