The Pop Cultures Food Fermentation Screen keeps fermenting vegetables submerged in brine to eliminate the mold that happens when they float to the top and become exposed to air. It was designed to fit in the neck of our 1-gallon glass glass jars. Fill the jar to the top with brine to keep the jar full and veggies submerged. Depending on the length of your fermentation you may top up with a little additional water or brine as required. This ingenious little device replaces glass weights that do not work as well in the 1 gallon jar.
It also works well in 24 oz mason jars as it can be folded and inserted through the neck of the jar.
