Know before you buy
The waterlock design features a channel around the rim that you fill with water before placing the lid. This creates an airtight seal that allows CO2 to escape during fermentation while preventing oxygen from entering the jar, which is essential for preventing spoilage.
This jar holds approximately 5.75 quarts, or 5.46 liters. It is designed for large-batch fermentation, making it well-suited for substantial quantities of sauerkraut or kimchi.
This jar is crafted from high-quality stoneware, which is non-porous and food-safe. It will not absorb odors or flavors from previous batches, ensuring your ferments remain pure.
Hand washing is recommended to maintain the integrity of the stoneware and the seal. Avoid using harsh abrasives or a dishwasher to ensure the jar remains in top condition for years of use.
While the jar creates the necessary environment for fermentation, you will still need to use fermentation weights to keep your vegetables fully submerged beneath the brine. This prevents surface mold and ensures even fermentation.
