Hi gang! Is there anyplace in SF where I can get mother of vinegar besides going out to the Richmond district to get it? If anyone has a piece of the gelatinous mass closer to the center of the city I will gladly pay them for some. I have become addicted to home vinegar making and although I have re-used my other mothers I am increasing production so I need more of them. Please advise, thanks and have a great day all!
