I tried to post this question earlier, but it doesn't seem to have shown up, so I am posting it again. My apologies if it shows up twice. I have inherited some really old wine - we opened one bottle - a 1971 Chassagne-Montrachet Chenevottes. I believe it was supposed to be a kind of chardonnay, but it had changed color to a tawny amber and tasted a bit like a slightly off sherry. I attach a photo. Neither of us could manage a second sip. Any ideas on what to do with this kind of thing? Cook something with it? Make vinegar out of it? Toss it?
