Short facts : The longer ageing gives it the more intense flavour and dark colour

Dark soy sauce is a type of soy sauce that is darker in colour and has a thicker consistency compared to regular soy sauce. It is typically aged for a longer period of time, resulting in a more intense flavour and darker colour. Dark soy sauce is commonly used in Chinese and other Asian cuisines to add colour and depth of flavour to dishes such as stir-fries, marinades, braises and dipping sauces.
