you can and cant
Only if you want what every you are cooking to taste like vinegar.
Red wine vinegar is for cooking/eating while white isn't. There also may be residue with the red wine that you won't get with the white.
brown rice vinegar OR Chinese black vinegar (cheaper) OR red wine vinegar + sugar or honey OR sherry vinegar OR fruit vinegar
No, White vinegar is plain Acetic acid in water, but either as a simple chemical mix (usually very cheap or cleaning grade vinegar) or through fermentation of distilled alcohol (akin to Vodka). White wine vinegar is made from the fermentation of real White wine. As such White vinegar has a simple acidic taste, whilst White Wine vinegar retains much of its original White wine taste, with its alcohol replaced by the Acetic acid of vinegar.
Red wine vinegar will result in a much tarter flavor than red wine and will not give you ideal results. If you're worried about the alcohol in red wine, don't be...it will evaporate during the cooking process.
Red wine vinegar is not a combination of vinegar and red wine. It is red wine that has turned to vinegar, the alcohol being converted to acid.
No vinegar is different from wine.
You probably can, but keep in mind that port is much sweeter than red wine.
It will change the taste.
Two different items you will change the outcome of the dish. I would stick to the recipe.
Red wine vinegar is red wine which has oxidized to turn into vinegar. Unless your vinegar is what is called "non-brewed condiment," ALL vinegar is oxidized alcoholic liquor. Wine vinegars are made from wines, cider vinegar is made from fermented apple juice, malt vinegar is made from a simple beer, etc.
yes you can _______ Red cooking wine would be a better substitute as sherry has a red wine base. White cooking wine wouldn't have the same depth.
