It means that unless a wine is particularly delicate it can probably survive being chilled down and then allowed to get back to room temperature without being noticeably the worse for it. On the other hand, fridge temperature is too cold to keep wine in for long periods, so if you had actually been keeping the bottle stored in the fridge for more than a few days, the cold may well have killed the wine anyway.
Anyway, the only way to to know for sure is to open it up and try! Don't just throw it away without trying it, for heaven's sake!
Oh, ok. Well, it was in there for about 2 weeks....intended dinner that went awry....
Well, I guess it's open it and try it! Although, I've never had this particular wine before so I don't know what "bad" tastes like.
