I think that bursting should depend on the vessel the alcoholic beverage is in. For example, wood and metals are not brittle materials and it would be unlikely for them to burst. Wood or weaker metals (used in mugs or goblets ) would probably crack slowly during the freezing process, while stronger metals may not incur any damage at all, or perhaps they would require multiple freezing cycles to become damaged. Also waterskins should be able to stretch a slight amount, thus preventing them from bursting also, although there could a small chance for them to be damaged as well.

The other materials used in vessels are glass and bone, both of which are brittle. Bone would be fairly strong and resistant to bursting (while still being able to burst), especially in the case of horns since they are reinforced with metal. Wine glasses would be the most likely to burst because glass is relatively weak and shatters easily.

Additionally, due to the freezing point of ethanol being -114°C, the alcohol content of a beverage should play a role in determining if the beverage will freeze. For example, potent vodka would only freeze under extremely cold temperatures (if such a temperature exists in Middle Earth). On the other hand, light ale would freeze at almost the same temperature as water.
