Know before you buy
The lid features a rim that sits in a water-filled channel on the jar's neck. This creates an airtight barrier that allows CO2 to escape during fermentation while preventing oxygen from entering the jar.
Yes, the set of weights is specifically designed to fit the 2-quart capacity of this jar. They provide enough pressure to keep your vegetables fully submerged beneath the brine, which is critical for preventing mold.
Absolutely. The waterlock design removes the guesswork of burping your jars manually, making it an excellent choice for those new to fermenting sauerkraut, kimchi, or other small-batch pickles.
Stoneware is opaque, which protects your ferments from light exposure that can degrade quality over time. Additionally, the weight and durability of the material provide a stable, temperature-consistent environment for your cultures.
Simply check the water channel every few days to ensure it hasn't evaporated. Keeping the channel filled with water is the only maintenance required to maintain the oxygen-free environment.
