I occasionally come across recipes that call for vinegar, but don't specify which of the many varieties they mean. (A recent example is this recipe for a corn and pepper salad, which just says "2 tbsp. vinegar".)
While I recognize that sometimes this may just be that the recipe is badly written, I've encountered it often enough to wonder: is there a "standard" or implied type of vinegar that should be used when a recipe simply calls for vinegar? Or is it assumed that the chef will be familiar with the flavor profiles of the dish they are trying to make and will be able to choose an appropriate vinegar by their own knowledge and discretion?
I've been unable to find an authoritative answer to this: other forums provide conflicting answers with no documentation or reasoning for the answer put forth, or make it seem like your only options are white vinegar and cider vinegar.
