Stable pressure: These weights maintain consistent pressure to keep ingredients submerged and fermenting properly, supporting successful fermentation. They function as canning weights for fermenting and as glass weights for jars. Glass construction: Made from glass, these weights are sturdy and longlasting, providing reliable performance for all your fermenting needs. They are suitable for wide mouth jars and serve as jar weights. Wide mouth compatibility: Specifically designed for wide mouth jars, the weights allow easy filling and placement, helping keep contents submerged and fermentation even.

They work as glass weights for wide mouth fermenting. Use scenarios: Kraut or kimchi in wide mouth jars: place these weights atop shredded cabbage or vegetables to keep them submerged and brine in contact for consistent fermentation. Quick pickles or vegetable medleys: use in wide mouth jars to ensure the brine stays fully covering the produce during primary fermentation. Smallbatch ferments or gifts: ideal for topping jars with weights to maintain submerged conditions and achieve clean, predictable results.
