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.
All of the colours in the vinegar are from natural sources, and the fermentation process requires time.
Non-brewed condiment is acetic acid mixed with colourings and flavourings, making its manufacture a much quicker and cheaper process than the production of vinegar.
[3] According to Arthur Slater, writing in the August 1970 edition of Industrial Archaeology, the Chief Metropolitan Magistrate ruled in a 1949 prosecution at Bow Street Magistrates' Court that the term non-brewed vinegar, which up until then had been used to market such acetic-acid solutions, was in contravention of the Merchandise Marks Act 1926 as it constituted a false trade description.
Slater goes on to state that after the unsuccessful appeal the trade association concerned announced that in future their product would be sold as non-brewed condiment.
