Can be used in conjunction with bung sleeves in order to maintain a proper seal with the barrel.
These bungs are made out of 100% Food Grade Silicone! And made right here in the USA, and in fact in California. Don’t be fooled by imitators selling cheaper bungs. These bungs tend to be from CHINA and are not composed entirely of food grade silicone. For your wine’s sake, we think you should go with a sure thing, especially a sure thing that is in constant contact with your wine.
