This red wine mother of vinegar is perfect for making up to 1 quart (32 oz) of red wine vinegar.
Directions: Add 8 oz of mother of vinegar and 8 oz of water to 16 oz of red wine to make 32 oz (1 qt.) of vinegar.
Place in glass, wood, or food safe HDPE plastic w/a removable top or holes allowing for aeration. Cover holes or open top w/cheesecloth or gauze to prevent insect infestation.
Allow to sit 6-12 weeks. Best growth is in temperatures of 80-85 degrees Fahrenheit. You can reuse the new mother that grows on the top of your vinegar. The mother may sink, but will regrow over time until done.
