Step 1

Use 1/2 or 3/4 full bottle of red wine. Place the wine in a large mouth glass jar or bottle. Cover the top with cheesecloth and secure it with a rubber band. Leave it in a warm place for 2 weeks. That's it. The natural oxidation process will turn the wine into vinegar. Taste then store in a sealed or corked bottle.

Step 2

Add 1 cup of mother and an entire bottle (750ml) of red wine to a large glass container. Cover and place out of direct sunlight. Over a 2 to 3 week period, you'll see a "skin" form over the top of the mixture. The skin will eventually sink to the bottom (about 2 weeks) and you'll have vinegar. As you use the vinegar, you can add more wine to the supply you've been making. Taste then store in a sealed or corked bottle.
