How to Make Kombucha Vinegar

Need a break from brewing kombucha but not sure what to do with your SCOBYs? Brew some kombucha vinegar! It’s made just like kombucha but fermented longer.

Why Does Kombucha Taste Like Vinegar?

Most people who try kombucha for the first time notice that it has a vinegary taste and smell. That’s because it is pretty similar to vinegar! Kombucha and vinegar are made with the same groups of microorganisms, yeast and acetic acid bacteria. That means you can turn kombucha into kombucha vinegar if you ferment it long enough!

If you’ve ever seen a kombucha SCOBY and a vinegar mother, you’ve probably noticed that they look almost the same. That’s because they are almost the same; both are made up primarily of acetic bacteria that produce acetic acid (vinegar). There are slight color differences because the tea in kombucha stains the SCOBY shades of brown.

Kombucha vs. Apple Cider Vinegar

The main difference between kombucha and vinegar is the amount of acid in each one. They both contain acetic acid, but vinegar contains a much higher concentration. Vinegar also takes a much longer time to ferment.

When making kombucha, little sugar is used in the beginning compared to vinegar; thus, kombucha has less acetic acid than vinegar. Vinegar is usually 5% acetic acid, while most kombucha contains less than 1% acetic acid.

Does Kombucha Have Vinegar?

Kombucha is supposed to have notes of sweet tea and vinegar when you taste and smell it. It does contain vinegar (acetic acid) naturally produced by the microbes in kombucha SCOBYs.

Kombucha Vinegar is Over-Fermented Kombucha

Since kombucha and vinegar are already so similar, it’s easy to make kombucha vinegar. Kombucha vinegar is simply a primary ferment that is started with more sugar than usual. Then, it is over-fermented.

I make kombucha vinegar regularly because it is a great way to postpone making more kombucha to drink while keeping the SCOBYs healthy and alive.

How to Make Kombucha Vinegar

I usually double or triple the amount of sugar I put in a primary fermentation batch to start some kombucha vinegar. So, for instance, I usually add 200 grams of sugar to a 1-gallon batch of sweet tea to make my regular kombucha. I add 400-600 grams of sugar to a 1-gallon batch to make kombucha vinegar. The more sugar you add, the more acidic it will be.

After Mixing up the sweet tea, I throw all of my SCOBYs in the jug with the fresh sweet tea, cover it with a cloth, and allow it to ferment undisturbed for a few months (usually three months). The SCOBYs love this and usually grow bigger and healthier during this time.

After it ferments for three months, I strain the vinegar from the SCOBYs and bottle it for storage at room temperature. At this point, I either start a new batch of vinegar or a fresh batch of kombucha.

Equipment for Kombucha Vinegar Fermentation

I suggest a gallon glass jar and a cloth cover with a rubber band for this recipe.

It would be best to use a cloth lid when making vinegar because acetic acid bacteria require oxygen to convert alcohol into acetic acid. I usually make cloth lids for fermentation by cutting up old t-shirts.

Here is all the equipment you need:

  • 1-gallon glass jar
  • a cloth lid and a rubber band
  • a kitchen scale

How to Use Kombucha Vinegar

Here are my favorite ways to use homemade kombucha vinegar:

  • for homemade salad dressing
  • in heirloom culturing recipes like this fermented green tomato recipe
  • I love to drizzle it over honeydew melon with raw honey and a pinch of salt.
  • In mineral-rich hydrating drinks (I like to mix a tablespoon of fruit vinegar into a quart of water with a splash of coconut water, orange juice, and a pinch of sea salt for a homemade hydrating “Gatorade”)

How to Make Kombucha Vinegar

Need a break from brewing kombucha but not sure what to do with your SCOBYs? Brew some kombucha vinegar! Kombucha vinegar is made just like kombucha but with more sugar initially and a much longer fermentation time.

  • Prep: 10 minutes
  • Cook: 30 minutes
  • Total Time: 1512 hours 40 minutes

Ingredients

  • 400–600 grams sugar
  • 20 grams tea
  • One kombucha SCOBY (or multiple)
  • about 4000 mL water

Instructions

  1. Gather your ingredients
  2. Boil your water and dissolve the sugar in the water.
  3. Steep the tea in the hot sugar water for 5 minutes. If using tea bags, simply remove them. If using loose-leaf tea, strain all the tea leaves from the mixture.
  4. Allow the sweet tea mixture to cool completely. It should be room temperature before moving on to the next step.
  5. Once it is cool, add the kombucha SCOBY(s). Some SCOBYs float, others may sink to the bottom, either way it’s fine.
  6. Cover the jar with a tight-weave cloth lid and rubber band. You must use a cloth lid to allow oxygen flow.
  7. Keep the jar of sweet tea with the SCOBYs at moderate room temperature, out of direct sunlight for about two to three months undisturbed.
  8. Strain the SCOBYs from the vinegar, bottle the vinegar, and store in air-tight bottles at room temperature.
  9. Start another batch of vinegar or kombucha with the SCOBYs.

    This phenomenal—just the thing I didn’t know I needed! I just bottled my apple cider vinegar today, and have a free crock + lonely scoby. Thank you for another fabulous recipe, friend!

    Thank you so much. How long can you keep this vinegar and do you need to burp the bottles once in a while?

      the vinegar lasts a very long time. Once it’s fully fermented it shouldn’t produce any gas, so no need to burp!

      I think so! My kombucha vinegar recipe How to Make Kombucha Vinegar gives you vinegar that is acidic enough for oxymels.

    I have a batch of blueberry kombucha that came out over yeasted(at least thats how it tastes) and overly carbonated. I did not put extra sugar in it initiallly, but do you think I could turn this into kombucha vinegar by adding sugar at this stage? Or is it too late?

combined two of the best fermented foods to make the best pancakes. And yes, you can ferment the batter overnight in the fridge for easier digestion.

Roasting garlic increases beneficial garlic compounds like diallyl sulfide and diallyl disulfide — or DADS, for short. Both of these compounds have been studied for their anti-inflammatory (anti-cancer), antioxidant, and antifungal properties.

It’s definitely a sauerkraut you should keep in your rotation.

To get the recipe google “garlic sauerkraut.” and you’ll see mine it’s the first one.

I know, I know, I’m making everything with cottage cheese right now. But how can I not? Cottage cheese is one of the most protein-rich fermented foods.

If you love ice cream and cheesecake-like flavor, you’ll love this recipe. it’s high in protein, requires only four simple ingredients, and does not require churning. So, you do not need an ice cream maker!

A half-cup serving of this ice cream has 12 grams of protein, making it a healthy and balanced sweet snack. Get the recipe from the recipe index linked in my profile.

Bok choy is similar in texture to Napa cabbage and Bok choy is similar in texture to Napa cabbage and lovely for fermentation. 

Since bok choy and all cabbages grow low and very close to the soil, their microbiome composition is wonderful! This makes all cabbages easy vegetables to ferment, and fermented bok choy is one of my absolute favorites.

Google fermented bok choy and you’ll see my recipe, it’s the first one. ☝🏼 #cabbage #fermentation #homestead
