the most commonly used vinegar is white wine vinegar. It is less acidic than plain distilled white vinegar and has a deeper flavor because it is a vinegar made from white wine, which makes it perfect for making salad dressings. We did a test with distilled white vinegar and in a pinch, you can still use it to make homemade Italian dressing. If using distilled vinegar, you might add a little less, or just add it to taste.
