I don't think having a bottle of wine out is that odd. It does have a flair of bon vivant about the person doing it and it fits my concept of Wilson. On the other hand, having WHITE wine out is odd as it needs to be served chilled usually. So either he finished it and left the empty bottle around, or he forgot to put it back into the fridge after having a glass... either way, it's terribly wasteful.

I think if they were trying to imply a drinking problem they'd show more than just one bottle... just use a different imagery. But that's just a gut feeling.
