How to make vinegar stronger?

In this brief article, we are going to answer the question “Can you make vinegar stronger”, discuss the different methods of making vinegar stronger.

How to make vinegar stronger?

You can make vinegar stronger by the following methods.

  • Perform fermentation of vinegar by continuously adding alcohol to the fermenting vinegar the resulted acidity of the fully fermented vinegar will be higher.
  • Azeotropic distillation of vinegar in the presence of azeotropic forming agents e.g, ethyl acetate, ethyl n-valerate or 4 methyl-2-pentanone etc

Fermentation of vinegar by adding Alcohol: 

If we continue to add alcohol in fermenting vinegar then the acidity (strength) of the fully fermented vinegar will be increased. Resulted acidity will be the sum of Actual acidity and quantity of alcohol in fermenting vinegar. 

The content of alcohol should be greater than required resulted in acidity after fermentation. By this method under conventional conditions, we can achieve a maximum of 11-12% of acidity. Which means a maximum of 12% acetic acid.

Azeotropic distillation: 

There is a patent azeotropic distillation of vinegar (US5160412A). Azeotropic distillation is a method of distillation in which water is removed from the mixture of water and acetic acid in the presence of azeotropic forming agents e.g, ethyl acetate, ethyl n-valerate or 4 methyl-2-pentanone etc.

Water and acetic acid are non-azeotropic mixtures therefore we perform azeotropic distillation in the presence of azeotropic forming agents.

What determines the strength of vinegar?

  • PH of the solution, which measures its acidity. Lower the PH, higher the acidity 
  • The concentration of acetic acid.

Can you increase the strength of vinegar?

Yes, you can increase the strength of vinegar but there are several things you need to be aware of. These include: 

  • Do not increase acetic acid level above 8% if you’re making it for consumption
  • Vinger must have 4% of acetic acid

Does table salt make vinegar stronger?

No, table salt (NaCl) is a neutral compound. Therefore it does not affect the PH of acetic acid (vinegar). Acetic acid is a weak acid because it does not ionize completely in the aqueous solution. 

When an acid ionizes it produces hydrogen ions (technically Hydronium ions). These hydronium ions are responsible for the level of acidity (i.e PH). table salt is neutral so, it does not affect the PH of vinegar. 

Can we distil vinegar by evaporation?

No, we can not distil vinegar by evaporation because the boiling point of water (100C) and acetic acid (118C) are very close to each other. If we evaporate then eventually we also lost acetic acid at (100C). Evaporation is always occurring even at room temperature. We are smelling vinegar due to its evaporation.

How to make 5% vinegar at home?

  • A simple way to make 5% acidic vinegar is to mix ½ cup of acetic acid and 1 gallon of water 
  • To make 30% acidic vinegar mix 3 cups of acetic acid with 1 gallon of water
  • In a nutshell, every cup of acetic acid in 1 gallon of water increase acidity by 10%

Usage of vinegar:

We are a huge fan of vinegar because it is non-toxic, cheap, naturally available and versatile.

People use vinegar to clean windows, remove stains, kill weeds, soft and rigid egg whites, relieve the pain of insect stings and sunburns, remove dog smell from clothes, disinfect fresh fruits and vegetables and treat a variety of ills.

Never forget the use of vinegar in pickles, as flavouring ingredients in the dressing of salads and in the refreshment of summer drinks.

For drinking and eating purposes:

  • If 5% vinegar does not irritate your stomach and the digestive system then enjoy your vinegar in pickles, dressings drizzled over cooked vegetables etc.
  • But don’t start drinking diluted vinegar as it is still acetic acid. It can harm your mouth and digestive system. A tablespoon is enough for dressing in salad and for drinking purposes.
  • Take special care of vinegar and make sure it should be out of reach of children because excess drinking may cause serious burns.

Is vinegar safe for the home cure?

  • Never use strong vinegar and vinegar preparation to whiten your teeth because it’s acidic and may damage the enamel of your teeth and injure sensitive tissues.
  • Leave the hair conditioner and rinse your hair with diluted apple cider vinegar in a quarter or so warm water ( the vinegar will remove residues, protect your hair from dividing and give your hair a sleek, well-conditioned look.

Is vinegar safe for the Garden weeds?

  • Strong vinegar is used to kill weeds approximately 20-30% of acetic acid. Store the vinegar in a lock and label it. Use chemical resistant gloves and eye protection, full sleeves and a safety cap before spraying in the garden.
