Sadly, we just haven't been drinking as much wine now that we have a little one in the house. As a consequence I have a couple of open bottles of wine (both red and white) which have been sitting in the fridge for a few months (how sad!). I am wondering if I can still use them for cooking? Can I use them in recipes that call for wine or wine vinegar? I'm planning on making a pot roast this weekend and wanted to use some red wine. I don't want to open a new bottle since it won't all get used. If I use the old, opened bottle of red wine will it come out tasting funny? I don't want to ruin the roast since it is organic and grass fed (and therefore expensive).
If you don't advise using the wine with the pot roast, is there anything else I can use it for? Or should I just dump it so that it is no longer taking up room in my fridge?
