Step 1

In an airtight container, combine 1 cup of unpasteurized apple cider vinegar with 2 cups of unrefined sugar.

Step 2

Shake the mixture until the sugar has dissolved completely.

Step 3

Add 1/4 teaspoon of active dry yeast to the mixture, seal tightly again, and store it away from direct sunlight for 2-3 months or longer if desired.

Step 4

During this time, shake the container daily to ensure proper fermentation takes place and strain out any solids that form on top.

Step 5

Once the vinegar has reached your desired taste, strain out any solids that have formed on top.

Step 6

Store the black vinegar in a sealed bottle or container in a cool, dark place.

Step 7

Note: The longer you let the mixture ferment, the stronger and richer the flavor will become. Use your homemade black vinegar in your favorite recipes as a flavorful and healthy substitute for other vinegars.
