As vegetables ferment, they release carbon dioxide. This pressure must be vented to prevent the jar from exploding, but opening your jar to "burp" it allows harmful oxygen in which can spoil your food with mold. Enter the Sauer System. Made of durable, BPA-free components, the Sauer System is everything you need to regulate the pressure pf your ferment safely, producing mold-free results every time.
