  1. Malt vinegar dates back at least 5,000 years. Traces of this vinegar made from fermented barley have been found in ancient Babylonian texts dating back to 3,000 BC. This makes it one of the oldest prepared food products in history!
  2. It was used as a medicine in ancient times. Greek physician Hippocrates, who lived in the 5th century BC, recommended malt vinegar mixed with honey to treat coughs and colds. People also believed it helped heal wounds.
  3. Malt vinegar can be made from other grains too. While barley is the most common grain used, malt vinegar can also be made from rye, wheat, rice, or corn. The starch in the grains is first converted into malt, which is then fermented into vinegar.
  4. There are two main types: distilled and non-distilled. Distilled malt vinegar is purified through steam distillation, resulting in a clear product. Non-distilled vinegar has a cloudier, brown appearance from leftover proteins and yeast particles.
  5. It’s called “non-brewed condiment” in the UK. Due to legal definitions for products allowed to be labeled as “vinegar,” many malt vinegars sold in the UK bear the name “non-brewed condiment.” But it’s chemically nearly identical to malt vinegar.
  6. Fish and chips is the #1 use. Malt vinegar is the perfect match for hot, crispy chips. The British soak their fish and chips with it, using about 100 million liters annually just for this purpose alone!
  7. It’s loved by Brits and Canadians. Fish and chips aside, malt vinegar is a popular table condiment in Britain sprinkled on foods like salads, roasted meat, and jacket potatoes. It’s also the vinegar of choice for sprinkling on fries in Canada.
  8. The “malted barley” gives it a unique taste. Malt vinegar gets its distinct flavor from the malted barley (or other grains) used to make it. Malting refers to soaking and germinating grains to activate enzymes that convert starches into sugars.
  9. It has a stronger acetic acid level. The acetic acid is what gives vinegar its sourness. Malt vinegar contains 4-8% acetic acid by volume, compared to 5-6% for wine vinegar and 4-7% for cider vinegar.
  10. It lasts 3-4 years unopened. An unopened bottle of malt vinegar will stay good for about 3-4 years past its bottling date if stored in a cool, dark place. Once opened, it will remain usable for 1-2 years.
  11. The “mother” turns alcohol into acetic acid. Fermenting alcohol into vinegar requires the help of a culture called the “mother.” This gelatinous blob of yeast and bacteria digests ethanol and produces acetic acid, turning wine into vinegar over time.
  12. It’s sometimes aged in wood. Higher quality malt vinegars are aged in barrels or casks made from wood like oak, chestnut, ash, or cherry. This can impart extra depth, complexity, and subtle sweetness to its flavor profile.
  13. It has some potential health benefits. Early civilizations recognized malt vinegar’s medicinal uses. Some studies show it has antioxidant effects in food, which can help prevent disease. But more research is still needed.
  14. It can be used for cleaning too! Household uses for malt vinegar extend beyond the kitchen. Its acetic acid content gives it properties that break down grease, soap scum, and stains. It’s great for making natural cleaning solutions!


From ancient Babylon to modern Britain, malt vinegar has been a versatile kitchen staple for thousands of years. Its unique malted flavor brightens up fried food, salads, sandwiches, and more in households worldwide.

Beyond curing fish and chips, malt vinegar has an intriguing history. It was once used as medicine, then evolved into a popular condiment with higher acetic acid than wine and cider vinegars. And it still makes a great natural cleaner!

So next time you sprinkle this sour brown elixir onto your food, appreciate just how fascinating this fermented malt beverage turned vinegar really is. Its backstory is almost as rich as its flavor.
