Too much red wine (opened)
We've been tasting reds (zins, cabs) for a wedding reception. Now the question is how long will the opened bottles keep -- room temp or refrig? Or is it coq au vin up the wazoo?
The only way to keep opened red wine is to use a vacuum pump system
with special caps which maintain vacuum. Even with this system, I
would not recommend keeping wine (refrigerated) more than 2 or 3 days
If the bottles are open or even closed with the original cork, maybe
the next day the wine will be tolerable. After that it can probably be
used as vinegar. I would not use it even for coq an vin.
I wouldn't go quite as far as bclevy... I'd say "it depends". But, *generally* I would use a vacuum sealer, refrigerate, and drink within 2 or 3 days. Use the initial cork, refrigerate, and drink the next day (morning). If you shove the cork back in and leave it in the fridge for a couple of days it should be fine to cook with.
That said, acidic tannic beasts (which is probably not what you are tasting) can pleasantly evolve opened for days on end.
My experience has been much the same as yours. When I leave behind that last glass or two in the bottle, I will typically just re-cork, and even if I just leave it on the counter rather than the fridge and come back the next day usually the wine is still entirely drinkable - some bigger wines (esp. younger zin and cab) will often improve after a day and sometimes still be drinkable after 2.
I've experimented with various lower end options - vacuum pump, inert gas, etc. - and found only minimal difference (perhaps an extra day's life, but still not "pristinely" preserved) so I don't bother any more.
I'd say you can keep 'em corked in the frig and drink within a week. Will it be as good as today? No. Will it be totally off, most likely not.
If it is wilted beyond your likes, but still not vinegar, you can make a sangria party over the weekend.
Besides coq au vin, you can use the wine in a great short-rib braise.
Just buy a can of Private Preserve and spray some of that into the bottles, if you don't already have or don't want to invest in a vacuum pump. Costs about $7.
