This question already has an answer here:
White wine and red wine have great flavors when added to a dish. But because I'm on medication, I'm not able to use wine (my body would have odd reactions when I consume food cooked in white wine) I wonder what is flavor-wise the closest nonalcoholic substitute for white wine and red wine?
I have looked at What is a substitute for red or white wine in a recipe? But the answers were not satisfactory. For example, chicken stock has a completely different flavor when substituted for white wine and so does white grape juice. What is [flavor-wise] the closest nonalcoholic substitute for white wine and red wine? Thank you!
