Mother’s Milk: Grow Your Own Vinegar


What do you do when you run low on store-bought vinegar and buying more is not an option? The answer is simple: You make your own.

I have not done this yet myself, but this is the most detailed information that I have gathered so far.

I have seen other versions that use brewer’s yeast, apple cider and myriad other items. If you have a different recipe, leave it in the comments. I would definitely like to see it, and I am sure that others would as well.

The first thing you need to do is to create your mother of vinegar. If you have ever purchased organic vinegar, odds are you have seen this clumpy whitish mass at the bottom of the bottle.

Never throw this out! This is an already thriving mother of vinegar. If you have some of that on hand, you completely cut out or at least get a huge head start on the first step.

If you are starting fresh, just follow the steps below.


  • Old wine still in the bottle with a cork, 16 oz. or so for the mother and more when you make your vinegar
  • Red wine or apple cider vinegar, a few tablespoons should be enough
  • Iodine for sterilization
  • Storage container (Ceramic or glass is preferred, but never use metal.)
  • Sterilized containers for bottling your vinegar
  • Cheesecloth
  • Rubber band
  • Ripe fruit to feed your mother
  • Optional: fine sieve, funnel, fruit juice

Make The Mother

To make a mother, take your leftover wine and add a splash (tablespoon) of red wine or apple cider vinegar. Re-cork the bottle and put it somewhere dark and warm to encourage the bacteria to attack residual sugar in the wine and start the fermentation process.

Temperature is not entirely crucial, but a stable and warm temperature of about 70 degrees will usually yield better results. It takes about two months to fully grow your mother. No matter how much you want to take it out and look at it, be sure to leave the bottle alone; otherwise, your mother could fail.

Note: If for some reason it doesn’t work or if you just don’t want to wait two months for maturity, you can buy mother of vinegar premade in a tub from a wine-supply store.

After two months has passed, slowly pour the contents of the bottle into bowl. Mother, when ready, is not very pretty. It looks a bit like something you might cough up after a bad cold.

There will also be some vinegar that has already started to form.

You can filter out with a fine sieve or coffee filter into another bowl to transfer to bottle. Don’t throw away any sludge; this is your starter.

While not appetizing, it is not harmful. And it can be used again and again to create more vinegar.

Feeding Your Mother

After you have created your mother, you’ll need to feed so that it will produce a regular supply of vinegar. Transfer your culture to a storable container with a wide mouth, like a crock. Another good vessel to use is a glass beverage container with a spigot, like for iced tea.

In the container, combine your mother with any leftover fruits that are starting to go bad or have become overly ripe. Berries, apples, pears and pit fruits are all good choices. Tomatoes are, too.

Just be mindful that whatever you add will contribute to the overall flavor.

Now, add enough liquid (an inexpensive bottle of wine or the dregs of the half-finished glasses of wine you’ve been saving in your refrigerator) to cover the fruit you’ve given the mother. You can also use fresh fruit juices in addition to the wine. Store-bought bottle juice is not a good idea, as it has preservatives that inhibit fermentation.

The container needs to be covered to keep dirt and insects out, but make sure that it can breathe. One of the easiest ways to do this is to lay a piece of cheesecloth over the mouth of the container and secure it with a rubber band.

Then put the mix in a warm dark place once again, checking on it every week. Continue to add liquid as needed.

A bit of scum will form on top as the process continues.

This just needs to be scraped off before you add more to the mix.

This, like the mother, is not harmful; it’s just the bacteria creating its own perfect environment.

Note: When you add liquid, your vinegar will be diluted until the bacteria can catch up; so if you’re in the mood for sharp vinegar, you’ll need to give the mix some time.

I recommend tasting at six weeks and going from there.

Voila!  Vinegar

Once the vinegar has a taste that is to your liking, it is time to bottle it.

This is where the iced tea container comes in very handy.

Pour from the spigot and bottle it in small, sterilized, airtight vessels.

If your container does not have a spigot, just ladle out the vinegar and strain it through cheesecloth before you bottle it.

If you don’t want the sediment, filter again with a fine sieve or coffee filter.

If you want to store your vinegar for long periods, heat it to 150 F for 30 minutes in a clean pot. Then you don’t have to worry about an airtight container.

You can also add fresh herbs to the bottles if you like. This will not only make your vinegar look nice, but infuse it with delicious herb flavors that make it perfect for marinating meats.

Your mother will continue to work and grow as you add to it. At some point, you’ll have more mother than room for vinegar.

You can scrape the extra mother off your container and start a new batch of vinegar, or you can share it with your friends.
