The only time vinegar could be a concern for Pesach is if it comes from wheat and is present in a significant amount. If the vinegar is derived from corn, rice, or any other kitniyot, that’s never an issue because the quantity will never be enough to pose a problem for Ashkenazim.
The general rule is: If a product with vinegar is kosher for Sephardim on Pesach, it is also kosher for Ashkenazim—as long as there is no wheat-based vinegar in a significant amount. A practical guideline is that if vinegar is listed as the third ingredient or lower, you don’t need to investigate its source.
So, Ashkenazim do not need to worry about the source of the vinegar unless it’s from wheat and in a large enough quantity to affect the product.
