How to Make Vinegar with a Vinegar Mother: Step-by-Step Instructions

Making vinegar at home is a rewarding and straightforward process. With a vinegar mother from Dump Bucket Vinegar, you can transform your leftover wine into delicious, homemade vinegar. Here are the step-by-step instructions to get you started:

Materials Needed:

  • Vinegar mother from Dump Bucket Vinegar
  • Leftover wine (red, white, or a mix)
  • Generic drug store hydrogen peroxide (3% solution is normal)
  • A large glass jar or ceramic container
  • Cheesecloth or a clean cloth
  • Rubber band or string
  • A dark, warm place for fermentation

Step-by-Step Instructions:

Step 1: Prepare Your Container

  1. Clean the Container: Ensure your glass jar or ceramic container is thoroughly cleaned, sterile, and dried. Any leftover residue or funkiness can affect the fermentation process, cause mold, or get into a fight with your mother.

Step 2: Add the Wine

  1. Fill the Container: Pour your leftover wine into the container. The amount of wine you use will depend on the size of your container and the amount of vinegar you want to produce. Aim for at least 1 quart (1 liter) of wine. If you have little bits of different bottles, combine them in one bottle and keep it corked until you have enough to start a new batch.
  2. Remove Sulfites: If your wine says it contains sulfites (a preservative that stops your mother from having a good time) or you suspect it does (most do) add a 1/2 tsp. of 3% hydrogen peroxide solution per 750ml of wine. 3% is the normal strength of your typical drug store hydrogen peroxide. Remember, hydrogen peroxide is just H2O2, so it will blow up the sulfites and just leave water. It’s not bad for you if you add a little too much.
  3. Dilute your Wine: For each portion of wine you add, add an equal amount of filtered or distilled water (no chlorinated water!) to dilute the wine. Your mother is happiest when the alcohol level is around 6%. Your starter wine may be 12-15%, so add a little extra water if you have a high ABV wine.
  4. Leave Space: Make sure to leave some space at the top of the container to allow for the addition of the vinegar mother and some air circulation. Your mother wants to breathe.

Step 3: Add the Vinegar Mother

  1. Introduce the Vinegar Mother: Gently place the vinegar mother from Dump Bucket Vinegar into the container. The vinegar mother will float or sink, both of which are normal. Dump Bucket Mothers are big, so you can pull them apart to get a fast start or to do multiple batches. Once it hits that tasty wine, it will start multiplying.

Step 4: Cover the Container

  1. Secure the Cloth: Cover the top of the container with a piece of cheesecloth or a clean cloth. Secure it with a rubber band or string. This allows air to flow in while keeping out dust and insects.

Step 5: Fermentation Process

  1. Store in a Dark, Warm Place: Place the container in a dark, warm place (ideally between 60-80°F or 16-27°C). A kitchen cupboard or pantry is often a good spot.
  2. Wait and Monitor: Allow the wine to ferment for 2 to 4 weeks. During this time, the vinegar mother will convert the alcohol in the wine into acetic acid, creating vinegar. You may notice a film forming on the surface; this is a good sign that fermentation is occurring.

Step 6: Taste and Complete the Fermentation

  1. Taste Test: After 2 weeks, start tasting the vinegar. When it reaches the desired acidity and flavor, it’s ready. If it’s not quite there yet, let it ferment for a bit longer.
  2. Remove the Mother: Once the vinegar is ready, carefully remove the vinegar mother and set it aside. You can use it to start a new batch of vinegar.
  3. Don’t wait too long: If you wait too long, the mother will eat all the wine, then start eating all the vinegar! Your batch will taste weak and watery. Put a date on the jar to remind you when you started. Don’t wait longer than 8 weeks after the last addition.

Step 7: Bottle and Store the Vinegar

  1. Strain the Vinegar: Strain the vinegar through a fine-mesh sieve or cheesecloth to remove any solid particles.
  2. Bottle the Vinegar: Pour the strained vinegar into clean bottles or jars. Seal them with lids or corks. Limiting oxygen will keep the mother from restarting and allow your bottle to age safely without getting weak. Half-empty bottles will sometimes have enough air for the mother to start growing again.
  3. Optional: Pasteurize your Vinegar: You can pasteurize your vinegar by gently warming it to 155 degrees and holding it there for at least 30 minutes. This low-temperature pasteurization is enough to kill off everything but not so hot that it changes the flavor. You can use a pot of water, or if you are fancy like us you can set up a temperature-controlled water bath with an immersion circulator like you would use for sous vide (like one from Anova or our antique from Boston Scientific).
  4. Store Properly: Store your homemade vinegar in a cool, dark place. It can be used immediately or aged further for more complex flavors.

Bonus Tips:

  • Experiment with Flavors: Add herbs, fruits, or spices to your vinegar during or after the fermentation process to create unique flavors.
  • Make Bottle Specific Vinegars: This is a great way to upcycle a special wine that might not be drinkable but still has great potential as vinegar. For example, I opened a bottle from my birth year that was a way over the hill – more over the hill than me! I started a batch of vinegar using only that bottle. It came out great and was a better tasting vinegar than it was a wine.

Enjoy your homemade vinegar! Whether you use it for cooking, salad dressings, or as a condiment, you’ll appreciate the rich flavors and the satisfaction of creating something delicious from leftover wine.
