Instructions:
- Prepare the Banana Mixture:
- Peel the bananas and mash them in a large bowl. You want to use very ripe or overripe bananas as they contain more natural sugars, which are essential for fermentation.
- Transfer the mashed bananas to a large glass jar. Add water and sugar if using. The sugar isn’t mandatory but can help speed up the fermentation process by providing additional food for the bacteria.
- Add the Mother:
- If using raw unfiltered vinegar, add it to the jar. This vinegar contains live acetic acid bacteria, which will start the fermentation process. If you have a vinegar mother from another batch, add it to the mixture.
- Cover and Store:
- Cover the jar with a piece of cheesecloth or a coffee filter. Secure it with a rubber band or string. This allows air to flow into the jar to facilitate fermentation while keeping out insects and debris.
- Store the jar in a warm, dark place for about 3 to 4 weeks. A pantry or a cabinet away from direct sunlight is ideal.
- Monitor the Fermentation:
- Check the jar every few days. You should start to see bubbles forming within a week, indicating that fermentation is occurring.
- After about 2 weeks, you might see a gelatinous layer forming on top of the liquid. This is the vinegar mother.
- Strain and Mature:
- After 3 to 4 weeks, strain the mixture through a fine mesh strainer into a clean bowl to remove all solids.
- Transfer the strained liquid back into the glass jar or into a clean bottle using a funnel.
- Cover it again with the cheesecloth and secure it. Let it sit in the same warm, dark place for another 4 to 6 weeks. During this time, the vinegar will clarify and mature.
- Bottle Your Vinegar:
- After the second fermentation period, taste your vinegar. If it has reached the desired acidity, it’s ready to be bottled.
- Transfer the vinegar into bottles using a funnel and store it in a cool, dark place. The vinegar will keep indefinitely and may continue to mellow and improve with age.
