Coq au Vin, rooster in wine, is a classic and no matter how old your rooster is the wine rejuvenates him.
Where I come from we put everything that is “over the best time” in wine and vinegar.
Traditional old horses or the former dairy cow as well as game would end up in a sour pickle for days or weeks and then turned in to a slow braised dish with red cabbage or sauerkraut and dumplings.
If you want to start a fight over food here, ask if an apple or raspberry vinegar should be used.
The France rooster in red wine was as well designed for the though problem. And it is in my opinion a much better approach to use a good red wine, a Pinot Noir i.e., to fix the problem than white wine and vinegar. So, if you never tried Coq au Vin grant your next rooster a funeral fest that celebrates his majesty and that make you feel like god in France.
