I was beginning to wonder if anyone around here had ever tasted wine before. Thank you,
Saltin, for restoring my faith in AT.
if it's red, and you kinda jammed the cork back in there, it should be fine...
just remember to drink it at around room temperature, as chilled seems to take away from the flavor a bit (for reds only of course)
Should be fine?? Assuming you want to make some sort of vinagrette, it should be fine, but as a drinking wine, it's finished. Using a vacuum sealer or some such device can extend a bottle for over a week, but a month is strictly out of the question because as soon as you open the bottle, you expose the wine to oxygen, which rapidly converts the wine into vinegar. I suppose you could drink it, but it would be nasty. Try buying a bottle of red wine vinegar next time. It's cheaper.
As for the temperature misconception, red wine SHOULD be chilled, but it should not be chilled to a low temperature like white wine. Good reds need to be chilled generally to around 50 degrees or so (depends on the type of grape). As a rule of thumb, they should only be room temperature in the winter -- in the summer, you want them cooled. Chilling takes away the flavor if overdone, but a lack of any cooling exacerbates the bad tastes of a wine -- try drinking crap wine warm, it's quite foul. Also, as a red wine warms, it releases its bouquet so hold a glass of red wine cupped in your palm (put the stem of the glass between your middle and ring fingers).
And, please, don't buy cheap wine -- spend a little more and support the GOOD wine growers out there. It only takes a minimum of $10 to find a decent bottle and $15 to get an even better one.
