Malt vinegar, is a type of vinegar which is made by malting barley, turning the barley into a beer, and then allowing the beer to turn into vinegar. The flavour of malt vinegar is quite distinctive, and very familiar to many fans of fish and chips. In addition to being used as a condiment, malt vinegar is also commonly used in chutneys, and it can be added to pickling mixtures. The strong flavour makes malt vinegar less suitable for more mild, delicate sauces and dressings.
