Benson tends to run a 5 to 10 year cellar life. If the wine has not been in a controlled wine cellar setting, it could then be past prime. You should drink it, if it tastes vinegary then use it to cook mushrooms.tonput on top of a steak. Wine can be used for more than just drinking. Cooking is a good use for wines past prime. Goodluck, I hope it still good.
Not sure, but it's wine... drink it! Most wines aren't meant to be kept for long periods of time.
