INGREDIENTS AND UTENSILS FOR MAKING GRAPE VINEGAR
  • Large glass jar
  • Red or white grapes

Grape vinegar recipe

You can do your own vinegar using any sweet grapes regardless of their color.
Green, red and black grapes are all suitable for making vinegar and you can mix them all together.
​The best would be to keep a glass jar in your kitchen, and to fill it little by little with grapes that appear to be a little damaged or overripe, when you're buying and eating grapes all along the season.
You can indeed add the good grapes too but it's only the grape itself that must be used, do not put the grape stems in your jar as they could stop the vinegar formation process.
Proceed as follows:
  1. Put the grapes into a glass jar.
  2. Smash them just as little as needed to force some pulp and juice out.
IMPORTANT: The lid should not be tight or else the jar could explode...the grapes need to breathe to allow for fermentation.
Within a few weeks you will notice your jar building juice out of the stored grapes and bubbles as well.
Collect the juice as soon as the fermentation process stops producing bubbles.
It is a matter of one to three months depending on the ambient temperature from start to the end of this stage.
  • Filter the glass jar contents and fill the juice into glass bottles or jars.
  • Keep them again until the "mother of vinegar" forms as shown in this picture and the ones below.
  • This is the white thick compound that is seen floating in this bottle.
  • When the mother of vinegar settles at the bottom and decomposes like powder, filter the contents again and enjoy your homemade and tasty vinegar. That's it!
