White vinegar mixed with red wine
Red wine vinegar can be imitated by combining white vinegar with red wine. A 1:3 ratio of white vinegar to red wine is a nice place to start. For instance, combine 3 tablespoons of white vinegar with 1 tablespoon of red wine. The ideal time to alter the mixture is after it has had a few hours to come together.
In a similar vein, you may combine red wine vinegar and white vinegar to get the full amount you require if you have some red wine vinegar but not quite enough for a recipe. Anywhere that asks for red wine vinegar, such as salad dressings, sautéed mushrooms, or caramelized onions, give this simple substitute a shot.
