Non-brewed condiment
Non-brewed condiment is a malt vinegar substitute created with water, acetic acid, flavourings and often caramel colour, generally used in fish and chip shops in the United Kingdom and Ireland.
Non-brewed condiment is much quicker and cheaper to manufacture than vinegar. According to Trading Standards in the UK, it cannot be labelled as vinegar or even put in traditional vinegar bottles if it is being sold or put out on counters in fish-and-chip shops.
