How to Make Fruit Scrap Vinegar at Home

Have you ever opened a bottle of wine, not finished it, and put the opened bottle back into your pantry? Then, maybe a few weeks to a month later, you go to retrieve that wine and find that it tastes like vinegar. What happened?

When alcohol is exposed to air (specifically oxygen), an aerobic bacteria in the air known as acetobacter bacteria converts the wine or other alcohols, like beer, into acetic acid, which is more commonly known as vinegar.

Thus, when your wine was exposed to the air after being uncorked, the acetobacter bacteria that naturally exists in the air went to work to start the process of making vinegar.

Do You Have to Make Alcohol Before Making Vinegar?

So how does this process translate when making vinegar at home using fruit scraps? Do you have to make an anaerobic (without oxygen) alcohol fermentation first, such as to create wine or beer, before you can make vinegar?

The good news is that the answer is no; you do not need to make alcohol first. Most home cooks are not set up with all the equipment necessary to make wine and beer or other alcohols at home. So not having to make alcohol is the beauty of making homemade vinegar with fruit scraps.

Aerobic Fermentation Is All You Need for Fruit Scrap Vinegar

The simple method of making fruit scrap vinegar at home uses a shortcut. Technically, the process of making fruit scrap vinegar at home does not follow the traditional two-step process involved in making vinegar. This traditional process begins with anaerobic alcohol fermentation and ends with aerobic fermentation.

Instead, you can make both the alcohol and the vinegar in one step, which is why making homemade fruit scrap vinegar is so easy.

You just need to leave fruit scraps (or cut-up fruit) and water mixed together in a loosely covered jar for about a week until it turns into a mild alcohol. The mixture turns into alcohol because the naturally occurring yeasts in the fruit and water mixture quickly gobble up all the natural fruit sugars.

Does this sped-up process of making alcohol produce a high-quality alcohol, such as a tasty wine or beer? Probably not. But it’s all you need to kickstart the ultimate vinegar-making process.

As the mixture starts its first alcoholic ferment, it will smell very yeasty and beer-like. Next, you just need to continue to let it sit in its jar, loosely covered, for about three more weeks until the mixture transitions to its second stage of fermentation and becomes vinegar!

How to Use pH Paper to Check Your Fruit Scrap Vinegar

If you’re new to making vinegar, especially fruit scrap vinegar with pineapple rinds or strawberry tops, you’ll want to make sure you have some pH paper or strips handy. You can use these strips to test to make sure that your liquid is acidic enough to decant as vinegar or if your liquid will need more time to turn into vinegar.

Steps to Use Your pH Paper

You can check to see if your vinegar is ready to decant with the following steps:

  1. Use a spoon to get some of the liquid from your vinegar container. You can keep it on the spoon or put it into a small cup. (You don’t want to put the pH paper directly into your vinegar container.)
  2. Tear off a strip of the pH paper.
  3. Dip the pH paper into the liquid on your spoon or small cup.
  4. If the pH paper shows a reading under 4.0, your vinegar is ready to decant.
  5. If the pH paper shows a reading above 4.0, you need to let your vinegar set for a while longer. Check your vinegar with the pH paper again in a few days.

In my pineapple vinegar video, I show you the process of checking my vinegar with pH paper. As you can see in the image below, my vinegar is between 3.5 and 4.0, so it’s ready to decant.

In general, when I am making raw apple cider vinegar, I like my pH to be between 3.0 and 3.5. However, when making vinegar with sweeter fruits like pineapple scraps, I find that it is difficult to reach a lower acidity level than 3.5. But as long as the pH is below 4.0, we have reached an acceptable level of acidity for homemade vinegar.

In contrast, the following image shows you a pH strip that’s been dipped into water. The pH of tap water can range from 6.5 and 8.5, but since the pH paper in this example only goes up to 5.5, the pH strip registers at the high end of the range (3.0 to 5.5), which is 5.5.

For testing vinegar, I’m only interested in pH values below 4.0. So a pH strip that shows 5.5 is definitely not vinegar!

What is Kahm Yeast?

When it comes to making fruit scrap vinegars, especially those that start with the scraps of sweet fruits, you might discover a white spider-web film forming across the top of your vinegar in the making. This white film is kahm yeast. It is not harmful, but it is persnickety! But don’t worry. Just skim it off the top, and then give your vinegar liquid a good stir.

Kahm yeast may return, but if it does, just do the same thing all over again. Skim off the kahm yeast and give everything a good stir. The kahm yeast should eventually stop forming and should no longer be a problem. And it will no longer be a problem once you strain and decant your vinegar.

  • Note: Kahm yeast is not mold. Mold is usually multi-colored and fuzzy. If you encounter mold, I recommend throwing out your vinegar and starting over.

What Can You Do with Fruit Scrap Vinegar?

Once you have successfully made your pineapple fruit scrap vinegar, you can use it in the same way you would use any vinegar in your pantry, such as making:

  • A tasty salad dressing
  • A flavorful marinade that also works as a tenderizer for tough cuts of meat
  • An addition to your bone broth ingredients to provide the acid to help draw out the collagen from the bones.

Should You Use Fruit Scrap Vinegar in Bone Broth?

I normally would not recommend using homemade vinegar to make bone broth, since you’ll lose the vinegar’s mother when the bone broth is simmering. Instead, a store-bought vinegar or alcohol would work the best, such as Red Vermouth, Port, Marsala, or Madeira.

However, if you’d rather not purchase store-bought vinegar or alcohol, your homemade fruit scrap vinegar, such as your pineapple vinegar or apple cider vinegar, would work well. You might even get a light and pleasant sweetness in your decanted bone broth when making it with fruit scrap vinegar.

Should You Use Fruit Scrap Vinegar for Cleaning?

I do not recommend using any fruit scrap vinegar for cleaning. Fruit scrap vinegars tend to lean on the sweeter side, which can make them a bit sticky. That’s the last thing you want in a homemade cleaning product!

However, in my homemade citrus vinegar video, I show you how to make a vinegar that’s perfect for cleaning. So be sure to watch that recipe video if you enjoy making homemade cleaning products.

How to Make Fruit Scrap Vinegar with Pineapple Rinds

Prep: 5 minutes
Fermentation Time: 30 days
Total: 30 days 5 minutes
Yield: 32 Ounces
Learn how to make fruit scrap vinegar with pineapple rinds to create a raw vinegar with a probiotic-rich "mother."

Equipment

  • 1 Sixty-four ounce jar
  • 1 Coffee filter or scrap of clean fabric
  • 1 Rubberband
  • Wooden chopstick or wooden spoon
  • 1 Bowl Large enough in which the jar can sit in and be steady.

Ingredients

  • 1 Pineapple rind, chopped into 1-inch pieces
  • Water, preferably filtered
  • 1/4 cup Sugar, optional

Instructions 

  • Place all pineapple scraps into the 64-ounce jar.
  • Add water to the jar to completely cover the pineapple scraps, leaving 1-2 inches of headspace at the top of the jar.
  • Stir the mixture well using a wooden chopstick or the handle of a wooden spoon.
  • Cover the jar with the coffee filter or clean fabric and secure it with the rubber band.
  • Place the jar into the bowl and set it aside in an undisturbed area of your kitchen out of direct sunlight.
  • Each day, remove the covering from the top of the jar and stir the mixture for about 30 seconds. Stirring twice per day is best. After stirring the mixture, return the covering to the top of the jar.
  • Within a few days, you should notice bubbling in the mixture, and the aroma should be yeasty and similar to the aroma of beer. If this does not happen, add the 1/4 cup of sugar and stir the mixture vigorously.
  • Continue to stir the mixture, preferably twice per day, for a total of 30 days.
  • After 30 days, use pH paper or strips to check the acidity level of the vinegar. (See video for how to use the pH paper.)
  • If the ph of the vinegar is 4.0 or lower, it has reached an acceptable acidity level. I generally recommend allowing your vinegar to reach a pH acidity level between 3.5 to 3.0.
  • To strain your vinegar, line a mesh strainer with a flour sack towel or some cheesecloth and place the lined mesh strainer over a clean bowl. Pour the vinegar into the lined mesh strainer. (See video for the straining technique.)
  • Transfer the vinegar from the bowl into a clean bottle that can hold 32 ounces. Or divide the vinegar into smaller bottles. Put a cap on the bottle.
  • You can store your homemade pineapple scrap vinegar in the pantry, but if you prefer, you can refrigerate it. Technically, because vinegar is highly acidic, it is what is known as "self-preserving" and does not need to be refrigerated. However, refrigerating your vinegar will not hurt it.
  • Although unlikely, if your vinegar develops mold or a foul smell at any time, discard it.
  • Technically, your vinegar should last indefinitely, but I recommend using it within one year. (See video for a more detailed explanation about shelf life.)
