Could you please explain why "wine bottle" is used in one sentence and "bottle of wine" is used in the other. Are they different?
1. Can you buy a bottle of wine to have with dinner?
2. It's such a mess in her. There are empty wine bottles everywhere.
The bottle of wine refers to the wine.
The wine bottle refers to the container.
You can have an empty bottle, or a bottle of wine, but not an empty bottle of wine.
