A question on wine. Of course there's a GA. Who do you think I am?

It's impossible for it to go bad, because you drink it all way before that could ever happen. Duh.

Wait...
How...
You had good wine, and it was left out for a month?
And the bottle isn't already empty right? I mean, I could understand an empty bottle sitting there... But... What is this? Is this real? You're trolling right?

Seriously though, I don't think that wine turns into straight vinegar in any more or less normal amount of time whilst you have the open bottle still corked and everything. In order for wine to be turned into vinegar it requires exposure to specific bacteria and to be diluted, etc. What you more likely mean is just the acetic acid that is the product of wine spoiling, which is part of what vinegar is. And even that takes it being fully open and exposed to the bacteria in the air for months. Though it may begin to taste bad to you well before then.

Edit: Found a link for you that's pretty good with the explanation - http://www.ravenoustraveler.com/2011/06/what-really-makes-wine-turn-into.html

Back in my drinking days I don't think I ever had a bottle of wine more than a few hours. :X
In fact, I never had a box of wine more than a few hours. -_-

I did find this for you, though: Linky

To be on the safe side i usually finish it the day i open it.

I don't drink alcohol because I'm boring :/.

where's the option "50+ years then sell it to an antique shop"? :3

May I ask why I have been blacklisted by you? I would appreciate knowing.

It really depends a lot on the wine and storage conditions. I personally don't like to keep a bottle open for drinking purposes longer than a couple days as a general rule due to the experience of some rather foul tastings beyond that point, but it really does vary a lot depending on wine and storage. The more wine that is in the bottle, the fresher the wine, the more sealed it is, and the cooler/darker it is, the less oxidation will occur and can be kept longer.

Here's a nice little pictographic:

How long a wine stays drinkable depends on so many factors:

• what kind of wine (and what quality)
• how much air was in the bottle (bottle mostly full lasts longer than a bottle mostly empty)
• how air-tight was it (more air-tight will mean the wine will last longer)
• what temperature was it at? (higher temperature will wreck the wine faster)
• was it exposed to direct sunlight? (darker storage conditions make the wine last longer)
• did you move the bottle around a lot, or shake it? (the more the wine moves, the sooner it gets wrecked)

If the conditions are right, leftover wine can be saved for quite a while, and have personally experienced wine still drinkable months later. If the conditions are all wrong, the next day could be too late. Generally, I'd say you've got about 3 days to drink your wine, maybe 4.

Bump :)

go for whiskey instead. :P

and why am I even blacklisted lol

I'd say a couple of days (up to a week) in a fridge (processes in wine would slow down in cold temperature), but if it were some older, or collectible wine - I'd drink it in a few hours, before the original taste were lost.

I put open bottle in a fridge door and it is ok for very long time. Seal it good before.

Whenever I open up a bottle of wine, i re-seal it with a vacuum sealer. Works perfect, I have one like this and the wine taste fine after a few weeks. No problem. If you want a "real" guide see the pic below

I don't drink, but I leave corked wine bottles in my cupboard to cook with, and I've only had one spoil, and that was a big ass jug that I had in there for about five or six months. Usually it takes me about a month to use a bottle of wine.

.. Thought this was about the WINE simulator for linux.. Know nothing about actual wines sorry :(

Typically I don't drink it after it's been opened for more than a week or so... but usually, it never makes it past the first night for me. :)
