Yes, you can substitute apple-cider vinegar for red-wine vinegar; it works very well.
In fact, you can actually turn apple-cider vinegar into red-wine vinegar by adding 1/2 cup of red wine to a quart of apple-cider vinegar.
That question is really opinion-based. Yes, you can but no, it won't be the same! There is a clear and obvious taste difference between the two vinegars. However, they have similar acidity (between 5 and 6%), so they can serve the same function. In other words, that sharp acidic taste you want in a dressing, or that meat-tenderizing acid you want in a marinade, are there in both vinegars. But anyone with the slightest bit of a palate can taste the difference.
You can use apple cider vinegar instead of red wine vinegar for a salad dressing. This will likely give it a whole different flavor, and some people may even think it is not good.
No
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.
No,red wine vinegar does not contain any sugar.
Only if you want what every you are cooking to taste like vinegar.
You can use cider vinegar or rice vinegar and only the most discriminating palates will tell the difference.
Malt vinegar, white wine vinegar, white spirit vinegar. Spirit vinegar doesn't taste as good as any of the brewed vinegars. The closest substitute is probably white wine vinegar mixed with an equal quantity of apple juice. Failing that, mix apple juice with malt vinegar. Red wine vinegar would give a taste that you might not want.
Apple cider vinegar is a vegan product as it uses no ingredients that originate with animals. However, when necessary, another vinegar such as rice vinegar could be used, as could any red wine or simple apple juice combined with a tablespoon or two of white vinegar.
Malt vinegar, white wine vinegar, white spirit vinegar. Spirit vinegar doesn't taste as good as any of the brewed vinegars. The closest substitute is probably white wine vinegar mixed with an equal quantity of apple juice. Failing that, mix apple juice with malt vinegar. Red wine vinegar would give a taste that you might not want.
Yes, but it depends on the recipe: cider vinegar has a sweetness to it (like apples), whereas balsamic vinegar has a really strong, tannic taste (like a heavy red wine). If you don't have cider vinegar, but you think balsamic would taste too strong, use lemon juice, plain vinegar, orange juice, dry white wine, etc. If you aren't baking with the vinegar, then you can also opt to omit it.
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.
No, unless you get a seasoned vinegar. Plains white vinegar, cider vinegar, red or white wine vinegar, rice vinegar, champagne, raspberry vinegar -- all should be sodium free. Check the label if you're worried -- any sodium would be added and therefore must by law be posted on the nutritional label on the back of the bottle.
Absolutely you could substitute cider vinegar for red wine vinegar in barbeque sauce. Apple Cider vinegar is slightly sweeter and is a little more mellow, making it actually preferable in some recipes.
