I have always been told by my 'elders' to use apple cider vinegar for canning etc., and the white vinegar in salads and salad dressings. I know I like the white vinegar in my cucumber salad that I make much better than the apple cider vinegar, but always use the apple cider for pickles, any canning etc., Don't really know if it makes any difference or not, so it will be interesting to follow this thread.
