I cook with wine a lot. Usually I cook with whatever wine I'd be
drinking, but not always. I sometimes buy a special wine for a special
meal, but I don't usually cook with it. I think it's a waste of money
to use an expensive for cooking.
I always have on hand some lower priced burgundy, Merlot, chablis,
cabernet,,etc. on hand for cooking. They work fine.
