A glass weight that sits inside a fermentation jar to keep vegetables submerged below the brine. This is critical for safe lacto-fermentation — exposure to air causes mould rather than the desired fermentation.
Check the product listing for jar compatibility — most glass fermentation weights are designed for standard wide-mouth mason or kilner-style jars.
Yes, glass is inert, non-reactive, easy to clean, and does not leach any flavours or chemicals into the ferment.
Sauerkraut, kimchi, pickled vegetables, pickles, and any other lacto-fermentation project that requires keeping solids submerged.
Using an airlock lid alongside the weight gives the best results — it allows CO2 to escape while preventing oxygen from entering. EcoWarehouse stocks silicone fermentation airlock lids separately.
