Whether you live alone and have trouble going through an entire bottle fast enough or find yourself with half bottles left behind after dinner parties or holiday gatherings, every wine drinker has been faced with the conundrum at one time or another of what to do with leftover, no-longer-drinkable wine.

The important thing to note is that although wine that's been opened for too long might not taste good for drinking anymore but that doesn't mean it's unsafe to ingest. You can certainly pour it out (many people do) but why not do some experimenting with it in the kitchen and try using it in some recipes or try your hand at making your own vinegar?

Ideas for using leftover wine:
- Add flavor and body to tomato-based sauces
- Deglaze pans after roasting meat
- Braise vegetables in it
- Cook it down for use as a sauce and glaze base
- Use it in fondue
- Use it as a marinade for beef, chicken, and fish
- Make your own vinegar by simply letting it sit or by following this recipe

Some argue that you should only cook with wine you would also be willing to drink, but much of what makes wine taste good originally gets lost in the cooking process anyway. It's really just about personal preference.
