Is there any use for stale wine?
I opened a nice bottle of Bordeaux on Thanksgiving and only drank about half. It's been sitting on my countertop for over a week and I have no doubt it's far past drinkable. Is it too sour to cook? Does red wine even go bad? What should I do next time I open a bottle I know I won't finish?

There really isn't any such thing as "stale" for wine. Typically, wine goes bad after opening in one of two ways. The first way is when bacteria consumes the alcohol and metabolizes it into acetic acid and acetaldehyde. This causes the wine to have a sharp, vinegar-like smell. That's because it is essentially becoming vinegar. The other way wine can turn is that the alcohol can oxidize, causing a nutty, bruised fruit taste that is reminiscent of sherry. The wine loses its fresh fruit flavors and bright acidity.
It's worth noting that neither of these is likely to be dangerous, so you can experiment with them a bit. Go ahead and taste it, and see which thing has happened. If you like the way it tastes, there is no harm in drinking it. Many people actually like the oxidized taste, which is why sherry, madeira, and oxidative orange wines are popular. Chances are you won't love it straight, so here are some things you can do with oxidized wine:
Using wine that has become sour or "vinegarized" is a little more limited, but there are still things you can do:
So now on to what you can do the next time to make your leftover wine last longer. (There are some of us who swear that there's no such thing as "leftover wine", but that's a separate discussion.) Basically, there are two things that will make your wine turn: contact with air and warm temperatures. So you want to reduce those as much as possibkle. If you keep the leftover wine away from air and warm temperatures, you'll be really surprised how long it can stay good. So what should you do? Here are some steps:
